The Reynaud wines are the stuff of legend. Utter “Rayas” to a certain crowd and they will swoon. The singular style of this iconic Châteauneuf-du-Pape estate – pale, hauntingly aromatic, almost Burgundian in texture and incredibly long-lived – has a fervent following, a clan of Reynaud obsessives keen to seek out everything that Emmanuel Reynaud touched.  The property’s rustic charm – a far cry from the grandiose buildings of many famous estates – combined with the family’s inclination to shy away from their fame, happier quietly farming their vines, has only fanned the flames. Tucked away in the northern reaches of Châteauneuf-du-Pape, Ch. Rayas and its owners are elusive – only making them more sought-after.   There is no shortage of praise for these rare and special wines – whose appeal, given the Reynaud’s minimal-intervention approach, broaches the worlds of fine and natural wine. William Kelley is a loyalist, and is one of several to note how well the property performs in “off-vintages” – where the property’s distinctive profile shines through, above and beyond the vintage and region, revealing their “captivating perfume, sensual textures and eternal youthfulness”. Robert Parker described the 1990 Rayas as “one of the greatest young red wines I have ever tasted”. For Nicolas Grainacher (Vinous), “The substance, finesse and intensity packed into these wines make it hard not to fall in love with them.” Neal Martin (Vinous) perhaps put it most concisely: “God invented wine to drink wines like this.”    The history of the Reynaud empire  In 1880, Albert Reynaud, a notary from Avignon, lost his hearing aged just 45. No longer able to work as a lawyer, he bought an estate in Châteauneuf-du-Pape, in an area called Rayas, where he saw out his days farming vines, apricots and olives. In 1910, his son Louis Reynaud took over running the estate. Louis had studied agriculture in Angers and was particularly interested in viticulture. He uprooted trees to plant new vineyards and bottled the property’s first wine in 1920 – using the name “Rayas”, the name of the forest on their parcel of land. It was the beginning of Rayas as we know it today.  Louis famously added the wording “Premier Grand Cru” to the Rayas labels, a self-pronounced classification of the wine – and notoriously defying the appellation rules (introduced in 1936). Building the property’s reputation and sales, he started expanding the business. Between 1935 and 1938 he bought Ch. des Tours in Vacqueyras, entrusting his son Bertrand with the larger 58-hectare property northeast of Châteauneuf-du-Pape, not far from the town of Orange. Around the same time, he built a new cellar and winery at Rayas, bringing the buildings within the appellation’s boundaries. After the Second World War in 1945, Louis purchased Ch. de Fonsalette, an estate further north of Orange, in Lagarde-Paréol – and, with that, the full suite of Reynaud properties was in place.  By the time Louis passed away in 1978, the Reynaud wines were some of the Rhône’s most famous.  
After his death, his youngest son Jacques took over Rayas and Fonsalette, while Bertrand continued to run Ch. des Tours. With the shift in ownership at Rayas and Fonsalette, quality dipped a little – but soon Jacques was making wines that lived up to the Reynaud name.  The old vines at Rayas, planted on sandy soils, facing north/northeast, surrounded by pine forest, produce wines of exceptional elegance and aromatic finesse, wines with haunting perfume, pale colour and almost Pinot-like delicacy, yet phenomenal persistence and ageability.   Jacques was renowned for being eccentric. A recluse, happiest in the vines and never keen to welcome visitors, he was rumoured to, on occasion, lie in a ditch to avoid journalists or other members of the trade. His aversion to the limelight surely only added to the wines’ allure. He died rather suddenly in 1997, while shoe shopping in Courthézon. Having no children of his own, his nephew Emmanuel – Bertrand’s son, who had been running Ch. des Tours since 1989 – inherited both Rayas and Fonsalette, taking the reins across all three properties.  The transition between Jacques and Emmanuel wasn’t seamless, as Emmanuel renovated the estate and replanted parts of the site, but by the early 2000s quality was once more living up to the Reynaud name. The style has shifted between generations, and while Jacques’s wines were more structured and solid, Emmanuel favoured more sensual, perfumed expressions. Over the last two decades, little has changed across the Reynaud properties – the wines’ mythical status only confirmed with each release. The new generation – Emmanuel’s sons Louis Damien and Benoît – are now continuing the family’s legacy.    The Reynaud philosophy  The approach at Reynaud is old-school – here, tradition reigns. Modern monoculture is not the method – with various crops across the estates, and biodiversity nurtured with swathes of woodland. The vines – all bush vined, many with significant age – are farmed in exactly the way as they’ve always been, organically with minimal inputs, ploughed by horse.  The fruit is all hand-harvested, whole-bunch fermented with indigenous yeast in cement tanks. Since Emmanuel took over, parcels have all been vinified separately. Macerations are gentle, generally under two weeks with a single pump-over a day. Ageing is in large, old oak, with no new wood used anywhere across the properties – indeed the youngest demi-muid or foudre at the estate may well be 30 years in age. Sulphur additions are minimal, with only a small amount at fermentation and a final addition at bottling, with the wines bottled unfined and unfiltered. The method is simplicity at its finest, focused on expressing each site – and the results speak for themselves. The wineries are rustic farm buildings, offering only the basic requirements, with no modern technology employed – and, given the wines produced, not needed.  Grenache is the core of all the Reynaud wines – the grape that thrives in their terroir and is the magic behind Rayas. Beyond Rayas, Cinsault is used to bring elegance and suppleness, while Syrah was long avoided – used only at Ch. de Fonsalette. Louis Reynaud believed the variety belonged in the Northern Rhône, and other than the small portion that made it into the Côtes du Rhône, the rest of the Syrah was sold off in bulk under his reign (often to local restaurants, who used it in their sauces). The Côtes du Rhône Syrah cuvée only introduced under Jacques Reynaud’s tenure, at first sold to the restaurants who had seen its quality in their sauces. There is no Mourvèdre at any of the estates, as Emmanuel Reynaud believed that their soils are too dry for the grape.  The Reynaud wines and estates  The Reynaud family comprises three distinct estates – Rayas, Fonsalette and Ch. des Tours, although Fonsalette doesn’t have its own winery.   Ch. Rayas  Rayas is the original Reynaud estate, purchased in 1880, and takes its name from the climat. In the northern reaches of Châteauneuf-du-Pape lie the 12 hectares of vines, surrounded by 11 hectares of forest. Forget the region’s stereotypical galets roulés or pudding stones, known for their ability to hold heat, Rayas sits on red, iron-rich, sandy soils, over richer clay. The soils are poor and the bush vines planted at low density, with a mere 2,500 vines per hectare – yielding just 10 to 20hl/ha. Significant replanting took place in the 1980s, meaning the vines now average 40 years in age, although there are still some survivors from the 1940s.  The site’s northern exposition combines with the influence of the wooded areas, offering shade and humidity, making for an extended growing season and preserving freshness in the wines. The Reynauds are among the last to harvest, often only picking in October/November, as much as two months after their neighbours. The resulting wines, however, do not speak of intense ripeness – but are all about elegance and finesse.  While Châteauneuf permits 13 red varieties, at Rayas you’ll find only Grenache Noir, with two hectares dedicated to white grapes – Grenache Blanc and Clairette. The Grenache vineyards can be divided into three section: Le Levant, Le Coeur and Le Couchant, each taking its name from its exposure to the sun – respectively as it rises, at its peak and as it sets. Writing for The World of Fine Wine, William Kelley describes the three components of the vineyard thus: “Le Levant is the most floral and ethereal, contributing the wine’s spine; Le Coeur is the most complete, contributing Rayas’s skeleton; and Le Couchant, with its richer, more compote-like fruit tones, brings the fat.”  The fruit is all hand-picked. The Grenache is kept on its stems, the whole bunches crushed before a gentle maceration for maximum two weeks (one pumpover a day) and indigenous-yeast fermentation. The wine is pressed off and aged in old foudre for a little under two years.  The delicacy and finesse of the resulting wine is reminiscent of top Burgundy. Pale in colour, Rayas is deeply aromatic, with haunting floral notes and an ethereal, silken texture that balances the wine’s earthy, savoury intensity. Between 1,200 and 1,500 cases of the flagship Châteauneuf-du-Pape are produced each year. The wines age beautifully and Emmanuel himself recommended waiting 20-25 years before opening a bottle of Rayas to fully experience its evolution.  The white grapes are planted across three parcels in Le Levant, comprising two hectares. The Grenache Blanc was planted in the 1940s, ’50s and ’95, with the Clairette planted in 1986. Fermented in old (80 to 100 years old) foudre, purchased second-hand by Louis Reynaud (Emmanuel’s grandfather), Rayas Blanc is a 50:50 blend of Grenache Blanc and Clairette, aged in old oak for around 11 months. The wine is made in extremely limited volumes, with only 400 or so cases produced each vintage. Rich yet poised, this rare white is immensely fragrant with notes of almond and white flowers, intensely mineral and textured, and can age for at least a decade.  Pignan is sometimes considered a “second wine” at Rayas, but it in fact comes from it own, specific site on the estate, a single two-hectare block surrounded by pine trees on the northern edge of the property with less sandy soils. Also pure Grenache, made in exactly the same way at Rayas, it offers a more immediate and approachable expression of the Rayas style, yet similar perfume, purity and structure – and is still capable of extended ageing. It can, on occasion – and especially in cooler vintages, rival its older sibling, Rayas. Around 650 cases are produced each year.  The Rayas wines are all only released when entering their drinking window, with the reds often only emerging from the estate over a decade after the harvest.  Ch. de Fonsalette  The “latest” addition to the Reynaud galaxy, Ch. de Fonsalette was purchased by Louis Reynaud in 1945. The property is large, covering 120 hectares in total, but with 12 hectares of vines in amongst woodland, farmland and olive groves, north of Orange in Lagarde-Paréol. Today it sits largely within the Côtes du Rhône Villages Massif d’Uchaux appellation (established in 2005), however the wines are all labelled just as Côtes du Rhône. Further north, the microclimate is cooler than at Rayas, and stylistically the wines are more restrained than those of Ch. des Tours, for example, but not as ethereal as those of Rayas.  The soils here are very different to those at Rayas with gravel, sand and red pudding stones. The vineyards are planted to Grenache, Cinsault and Syrah for red grapes, and Grenache Blanc, Clairette and Marsanne for whites. The vines are generally old, with the oldest planted in 1929.  The philosophy in the vineyard and winery is exactly the same as at Rayas – and, as the property doesn’t have a winery of its own, the wines are even made at Rayas. The reds are whole-bunch fermented, with a maximum two-week maceration and one pump-over a day. The wines are aged in a combination of enamel-lined tanks and large, old oak, bottled around a year or so later.   There are three wines in the range at Ch. de Fonsalette. The Côtes du Rhône Rouge is a blend of 50% Grenache, 35% Cinsault and 15% Syrah, the notably high percentage of Cinsault giving the wine particular lift and aromatic finesse – a wine that whispers and draws you in. There is a second red, a Côtes du Rhône Syrah which is 100% Syrah – a structured, dark-fruited wine that offers restrained power and quiet depth. Under Louis Reynaud, this was sold off in bulk, only first bottled under Jacques Reynaud (from 1978) and sold locally, largely to restaurants, before being offered more widely under Emmanuel. The Côtes du Rhône Blanc is a blend of 80% Grenache Blanc, 10% Clairette and 10% Marsanne, producing a textural and complex white with notes of stone fruit and herbs, and a saline undertow.  La Pialade  This wine is a slight anomaly in the Reynaud line-up. Only made in certain vintages, La Pialade Côtes du Rhône is vinified and aged at Rayas, made with declassified parcels from either Rayas or Ch. de Fonsalette. The blend is typically 85% Grenache, 15% Cinsault and 5% Syrah. Produced in tiny volumes, and even rarer given it isn’t made every year, it is often described as an “everyday Rayas” – more open in style, but can match Rayas for its subtlety and delicacy, even if it does not have the same depth.  Ch. des Tours   Purchased by Louis Reynaud in the late 1930s, Ch. des Tours was Emmanuel Reynaud’s home estate – having taken over running the property from his father Bertrand in 1989. As it was entrusted to Bertrand from the beginning, and never managed by Jacques Reynaud, the estate has always stood apart from Ch. Rayas and Ch. de Fonsalette – however all three have fallen under Emmanuel since 1997. Benoît – Emmanuel’s son, who studied oenology in Switzerland – has recently taken the lead at Ch. des Tours, having worked closely alongside his father.  The property gets its name from the towers or tours that frame the château building. Located in Vacqueyras, not far from Orange and northeast of Châteauneuf, it covers 40 hectares, with grains and olives as well as grapes. As it was long run separately, the property has its own winery.  Although the Reynaud philosophy runs through all three estates, the wines at Ch. des Tours are stylistically distinctive, offering more structure, muscle and intensity versus the more subtle, high-toned, perfumed style of Rayas and Fonsalette. The winemaking is largely similar to at Rayas and Fonsalette, with fermentation is concrete and maturation in old oak. Although the red grapes are mostly whole-bunch fermented, this is the only property where small portions are destemmed. The range is more complex at Ch. des Tours with a selection of wines bottled under Ch. des Tours, some under Domaine des Tours and a rosé made under the Parisy label.  There are five wines under the Ch. des Tours label:  Vacqueyras: A blend of 80% Grenache and 20% Syrah, this is a structured and powerful wine made exclusively from the oldest vines on the estate.  Côtes du Rhône Rouge: A blend of 65% Grenache, 20% Syrah and 15% Cinsault, this is a supple, juicy red packed with fruit and spice.   Côtes du Rhône Rouge Grande Réserve: Only made in specific vintages, this is effectively the Vacqueyras declassified when there isn’t sufficient colour – made in 2002, 2014 and 2015.  Côtes du Rhône Blanc: Made in very limited volumes, this white is 100% Grenache Blanc – a floral, textural wine that is worth seeking out.  Côtes du Rhône Blanc Grande Réserve: Only made in certain vintages, this is not a declassified bottling (like its red sibling), but a special bottling of the property’s best Clairette and Grenache Blanc. The 50% Grenache Blanc, 50% Clairette wine was produced in 2003, 2014 and 2015.  The Domaine des Tours label is all sourced from Ch. des Tours however is a slightly separate project, generally offering more accessible wines, almost all labelled as IGP or Vin de Pays. There are four wines under the label:  Vin de Pays de Vaucluse Rouge: This is a deeply expressive field blend of Grenache, Counoise, Syrah, Cinsault, Merlot and a host of other varieties.  Vin de Pays de Vaucluse Merlot: This 100% Merlot comes from the richest, clay soils on the property, producing amore opulent and exuberant wine.  Vin de Pays de Vaucluse Merlot-Syrah: A blend of Merlot and Syrah, which shifts according to the vintage, is a concentrated wine that combines the generosity of Merlot with the spice of Syrah.  Vin de Pays de Vaucluse Clairette: This 100% Clairette is pure and fresh, driven by minerality.  Under its own label is Les Tours Grenache Blanc – a rich, ripe and generous 100% Grenache Blanc full of stone fruit, bottled under the Vaucluse appellation. The last wine from Ch. des Tours is the Parisy rosé, a dry, delicate Grenache/Cinsault Vin de Table designed for everyday drinking. The labels themselves don’t detail the vintage, with this information only visible on the cardboard case.  Which Reynaud wines are made where? Ch.

What is Krug?  Krug is one of the most famous Champagne Houses in the world. It is unusual for making only prestige cuvées and is prized by fine wine lovers, seen by many as the pinnacle of fine Champagne – competing with the likes of Cristal and Dom Pérignon.  When was Krug first made?  Joseph Krug established Krug & Compagnie in 1843 with a wine merchant friend, Hyppolyte de Vivès. Born in Mainz in 1800, Johann-Joseph Krug was the son of a butcher. He dropped the Johann, moved to Paris in 1834 and worked as a bookkeeper at Champagne Jacquesson before starting to blend his first wines with De Vivès, trials for what would eventually become the Krug project.  Is Krug still owned by the Krug family?  No – although the family is still very much involved.  When Joseph passed away in 1866, his son Paul took over the business. In 1868 he moved the business to 5 Rue Coquebert in Reims, the address still occupied by Krug today and home to its historic cellars. The company passed to Paul’s son Joseph II in 1910, but his wife Jeanne took the reins when Joseph II became a prisoner of war during the First World War. Joseph II’s nephew Jean Seydoux became a joint manager after the war, with the business passing to Paul Krug II (Joseph II’s son) in 1959 and then to Henri and Rémi Krug, who joined the company in the 1960s and took over in 1977.  Brothers Henri and Rémi were pivotal in developing the House – expanding the range, building its international reputation and overseeing its sale to luxury goods conglomerate LVMH in 1999. Although they continued to manage the House, the financial backing of LVMH only allowed Krug to thrive. In 2009, Olivier Krug – the sixth generation of his family – took over as Director of the House and remains at the helm today.  What is the Krug style?  Often quite deep golden in colour, Krug is renowned for its use of oak, choosing to ferment all its base wines in old 205-litre oak barrels, allowing micro-oxygenation. This, combined with long lees ageing (minimum six years for non-vintage and 10 for vintage wines), produces a powerful, broad and richly autolytic style of wine, layered with bread, biscuit and brioche notes. The huge number of blending components used for Grande Cuvée makes a particularly complex non-vintage – or as they prefer to call it, multi-vintage – wine. The House also favours picking on the earlier side to retain freshness in the wines. Dosage here is average with the wines labelled Brut, and dosage normally sitting around 5-6g/l in modern releases.  It's interesting to note that Krug feels Meunier is an important element in their blends (sometimes viewed as a lesser grape by Champagne Houses), valuing the mid-palate generosity it brings to wines. Meunier often represents 15-25% of the House’s vintage blends.   What are the different Krug wines?  Joseph Krug had clear ideas about how to make the best Champagne and famously outlined these in his burgundy-coloured leather notebook (which is on display at the Krug family headquarters today). He declared that the House would only make two cuvées, intended to be of equal quality. Cuvée No 1 was a non-vintage wine, conceived to be “the fullest expression of Champagne every year” (embodied today by Grande Cuvée), while Cuvée No 2 would express each vintage. He also firmly believed in the importance of site, writing, “We cannot obtain good wines without using good elements and good terroirs.”  For many years, the House continued to produce just two wines, but the range has since expanded. Although the non-vintage and vintage wines were intended to be equal in quality, the vintage wines command higher prices today.  The Krug range consists of six wines:  Krug Grande Cuvée: Grande Cuvée is Krug’s flagship non-vintage, or multi-vintage (MV), wine, and the modern Cuvée No 1, and previously known as Private Cuvée (until 1978, see below for more on this). There are up to 200 components in each bottling of the wine, combining over 10 vintages (the youngest six years old, the oldest over 20 years old). While it is the House’s “entry-level” offering today, the House holds back many of its best wines from top vintages for the wine. It spends minimum seven years’ ageing on lees prior to disgorgement, with an additional year on cork prior to release. Unlike many non-vintage wines, the goal is not for the wine to be entirely consistent between releases, but to make “the fullest expression of Champagne”. From 2011, this was acknowledged officially when Krug added the Krug ID to every bottle (see more below). In 2016, the House took this further and decided to add an Edition number to each release, starting with Edition 163 (for which the base year was 2007). Some collectors seek out particular editions of Grande Cuvée, with 164 (base 2008) or 168 (base 2012) unsurprisingly lauded. Half-bottles don’t have the edition number on the label, so you need to use the Krug ID to identify the specific bottling.  Krug Rosé: The House’s other non-vintage wine, Krug Rosé was created by Henri and Rémi Krug in the 1970s, with the first release based on the 1976 vintage, released in 1983. The wine is a blend of white wines, with around 11% still red Pinot Noir blended in, combining anything between 20 and 70 different components from five vintages, spending minimum six years on its lees. As for Grande Cuvée, in 2016 Krug added an Edition number to the Rosé label, starting with Edition 21 (base 2008).   Krug Clos du Mesnil: Clos du Mesnil is a single-vineyard vintage Blanc de Blancs Champagne, and one of Krug’s top wines. Champagne expert Richard Juhlin describes it as “the best wine in the world”. Henri and Rémi Krug purchased six hectares of Chardonnay in Le Mesnil-sur-Oger in 1971 and when they went to inspect the vineyards they discovered it included a walled 1.84-hectare plot in the heart of the village. On the wall is inscribed, “In the year 1698, this wall was built by Claude Jannin and Pierre Dehée Metoen and in the same year the vines were planted by Gaspard Jannin, son of Claude.” They replanted the site and at first the fruit was blended into the House’s other wines, however they found that the warmer microclimate – surrounded by buildings – produced a distinctive wine, and they decided to bottle it separately. The first vintage was 1979, released in 1986 – at a time when a single variety, single site wine was pioneering. Aged for minimum a decade on its lees, it is only made in certain vintages where the quality allows.  To date, the vintages of Clos du Mesnil produced are: 1979, 1980, 1981, 1982, 1983, 1985, 1986, 1988, 1989, 1990, 1992, 1995, 1996, 1998, 2000, 2002, 2003, 2004, 2006, 2008 and 2009.  Krug Clos d’Ambonnay: Pure Pinot Noir from a single 0.68-hectare plot, Clos d’Ambonnay is Krug’s other single-vineyard vintage wine. Henri and Rémi found this site on the edge of the village of Ambonnay, on the southeastern slope of the Montagne de Reims, in 1991, managing to purchase it in 1994. Like Clos du Mesnil, the site is a walled vineyard, with the walls dating back to 1766, although vines weren’t planted until the 20th century. The first vintage of the Blanc de Noirs was produced in 1995 and released in 2007. As with Clos du Mesnil, it sees long lees ageing (minimum a decade) and is only made where vintage conditions allow. Given the size of the vineyard, Clos d’Ambonnay is particularly rare.  To date, the vintages produced of Clos d’Ambonnay are: 1995, 1996, 1998, 2000, 2002, 2006 and 2008.  Krug Clos d’Ambonnay Rosé: The first vintage of Krug’s Clos d’Ambonnay Rosé is set to be released in autumn 2025, the 2008 vintage. The first new cuvée since the House launched Clos d’Ambonnay, the wine is a rosé from the same single vineyard, including 15% still red wine in the blend.  Krug Vintage: The other wine conceived by founder Joseph Krug, Cuvée No 2, was a vintage wine that the House still produces today. It is only made in vintages deemed worthy by the House and spends over 10 years on its lees prior to disgorgement.  Recent vintages produced of Krug vintage are: 1988, 1995, 1996, 1998, 2000, 2002, 2003, 2004, 2006, 2008 and 2011.  Krug Collection: In the 1980s, Krug introduced its Collection – a late-disgorged release of more mature wines, normally offered around 25 years after the vintage. These wines have been kept in the House’s cellars, ageing in perfect conditions. Releases to date include: 1981, 1982, 1985, 1988, 1989, 1990 and 1995.  What is Private Cuvée?  Private Cuvée was the previous name for Grande Cuvée, the House’s non-vintage wine, labelled as such from 1862 to 1978. Champagne expert Richard Juhlin notes that the style shifted with the name change, with Grande Cuvée a little lighter more Chardonnay-driven and more multi-faceted, however Private Cuvée was closer to a vintage wine in style with more weight. “The style from the 20’s to the 60’s is strikingly constant and if you find a bottle with a good level and with a price tag you can handle, it is a chance you must not miss,” he writes of Private Cuvée.  How much Krug Champagne is made?  Production for the House is kept firmly under wraps, however estimates suggest around 425,000 bottles are made each year.  What is Krug ID?  This six-digit code features on the back label of every bottle of Krug and allows the drinker to find out about their specific bottle of, with the first three digits indicating the quarter and year of disgorgement. You can look up the ID on the House’s website or app to find the blend, oldest and youngest wines, tasting notes, food and music pairing suggestions. The Krug ID was introduced in 2011, so only appears on bottles released after that date.  Does Krug own vineyards?  Krug’s expertise was historically winemaking and blending, and always operated as a négociant, as was the norm for the Grandes Marques in Champagne. Krug bought fruit from carefully selected sites to make their wines, but Henri and Rémi purchased the House’s first vineyards in 1971 – including the now famous Clos du Mesnil.  Today Krug owns 21 hectares of vines, representing around 20% of their production, supplementing this with purchased fruit. Krug sources its Chardonnay, Pinot Noir and Meunier from the villages of Ambonnay, Aÿ, Le Mesnil-sur-Oger and Trépail. All their contracts are for specific parcels, many based on generations-long relationships, with their oldest contract dating back to 1876.  Krug has been increasingly focused on sustainability, not using any herbicides or pesticides in its own vineyards and the estate vineyards are certified organic as of the 2024 vintage.  Who makes Krug?  As with any winery, there is a large team involved in producing Krug – including the growers supplying fruit and those in the winery at Krug. Eric Lebel was the longtime cellarmaster, from 1999 to 2019, handing over to Julie Cavil who worked alongside Lebel for 13 years before taking the reins at the start of 2020.  When it comes to deciding on the blends, there is a tasting committee, led by Cavil and usually with Olivier Krug. The committee meets every day between the end of harvest and March, tasting 15 samples each day (a strict maximum to ensure their judgement isn’t impacted by palate fatigue). Over the period, they aim to taste all 400 samples two or three times in total. Each taster has to describe each sample with just a single word, which cannot be duplicated by any other taster – something that Cavil feels helps give a better overall picture of the wines.  How is Krug made?  As already mentioned, all Krug’s base wines are fermented in old oak. They use 205-litre barrels, averaging 20 years in age, often retired at around 40 years. They do not block malolactic fermentation but do not encourage it, so some wines do go through malolactic fermentation. Post fermentation, the wines are transferred to stainless steel tank (they are not aged in wood, as at Henri Giraud, for example). The blends are decided by the House’s Tasting Committee (led by Cellar Master Julie Cavil) between the end of harvest and April, before being bottled and spending minimum seven years on their lees (10 years for the vintage wines).  Where is Krug made?  For almost two centuries, the wines were made at Krug’s historic premises in Reims, however as of 2024 the winemaking has moved to its new Joseph winery, just next to Clos d’Ambonnay.   What’s the deal with Krug and Burning Man?  Krug caused some controversy when it shot a marketing campaign at the Burning Man festival at Black Rock in Nevada in 2011. The shoot and brand were denounced by the Burning Man organisation for not complying with its principles, commercialising the festival and community.  Why is Krug’s bottle shaped differently?  Krug’s distinctive narrow-necked bottle was introduced in 1978, at the same time as it changed the name of Private Cuvée to Grande Cuvée. The House previously used standard Champagne bottles. Beyond making Krug’s bottles even more distinctive, the narrow neck is intended to reduce oxygen exchange over the ageing process.  How does Krug age?  Krug is renowned for its ageing potential – with all the House’s wines, including the non-vintage cuvées, designed to evolve in bottle. Champagne expert Essi Avellan MW notes: “All Krugs benefit from ageing. Five years after release, they tend to have opened up beautifully, showing more expression and a beautifully harmonious nature. Grand Cuvées are a real delight some 10 to 15 years after release, often at the peak of their expression. The vintages are all long-lived; thereafter it depends on the vintage (and the individual bottle, of course) as to how they age. When well kept, all should age for at least 15 years post-release, and the best for several decades.”  Explore all Krug listings, including the new releases of Grande Cuvée and Rosé, or read more about Champagne and sparkling wine

Earlier this month, I returned to Auxey Duresses to spend time at the Domaine and taste the 2026 Maison Leroy release in full. This was a significant visit.

We tasted more than 25 wines across vintages, appellations and styles, which allowed for a level of depth and comparative understanding that is rarely possible with Maison Leroy. It is a way of tasting that strips away hierarchy and focuses entirely on expression, timing and intent.

Having visited consistently for more than 12 years, and multiple times each year, I have seen many releases in different forms. I can say with confidence that this is the most complete and compelling Maison Leroy selection I have encountered. It is an exceptional release. The 2026 Maison Leroy collection tasted as a modern collection in the fullest sense. What gives it its shape every year are wines drawn from different years, now brought together at a point where Madame believes the wines have something extraordinary to say. However, this felt like the first Maison collection to begin to mirror, with real conviction, the superlative character of Domaine Leroy.

There is range here, certainly, across appellation, level and vintage. Each feels released at precisely the point where evolution had hardened rather than softened its definition.

That is what gives the release its outright drinkability — an unflattering expression to many, and perhaps one not preferred at the Maison, but these were wines of serious joy and poise.

What makes the 2026 release especially significant is that it presents Maison Leroy in a form that feels entirely of the present, while carrying the same gravitas, refinement and inner control that have come to define the Domaine at its highest level. The result is a Maison collection of unusual stature: one that stands on its own terms, yet also comes closer than any previous release to reflecting the authority and brilliance associated with the Domaine’s dominant era. Process and Élevage To understand Maison Leroy, one must first understand the process. Every wine is tasted blind by Madame Lalou Bize Leroy before any decision is made. Hundreds of wines are assessed each year, with producer, appellation and reputation set aside. Rarely do new wines make the cut. Only when a wine meets her standard does it carry the Leroy name. That responsibility remains directly hers. It is only the beginning. Once secured, the wines are transferred to the cellars, where they enter a long and closely controlled élevage. For the reds, with Bourgogne Rouge the sole exception, every wine completes its élevage in used Domaine Leroy barrels, regardless of appellation. Village or premier cru, classification gives way to quality. Each wine is handled according to its potential, allowing a level of refinement and integration that rises above hierarchy. The same philosophy applies to the whites. With Bourgogne Blanc the exception, the wines complete their élevage in used Domaine d’Auvenay oak barrels. The foundation of Maison Leroy Maison Leroy is the original cornerstone of one of Burgundy's most influential and enduring families. Founded in 1868 by François Leroy in Auxey-Duresses, the business began as a négociant operation with access to vineyards across the Côte d'Or, including Auxey-Duresses, Meursault, Pommard, Chambertin, Musigny, Clos Vougeot and Richebourg. At the time, the wines were not bottled under the Leroy name, instead being sold through the Comptoir des Propriétaires de la Côte d'Or. Under Joseph Leroy, the Maison expanded commercially, before Henri Leroy fundamentally reshaped its trajectory. In 1942, during a period of uncertainty in Burgundy, Henri acquired a 50% stake in Domaine de la Romanée-Conti. His stewardship was instrumental in restoring and elevating the estate to its modern standing at the very pinnacle of fine wine. While the négociant arm continued, it was under Lalou Bize-Leroy that Maison Leroy assumed its modern identity. Joining the family business in 1955 and taking control in 1971, Lalou transformed the Maison into something far more exacting: a house defined by independence, absolute selection and long-term vision. Maison Leroy sits at the centre of a wider Leroy ecosystem, alongside Domaine Leroy and Domaine d'Auvenay – each representing distinct, yet complementary, expressions of the same uncompromising philosophy — wines that consistently transcend AOC convention. The forthcoming Domaine Leroy release will offer a contrasting perspective – rooted in vineyard ownership and production, yet entirely equivalent in rarity, prestige and ultimate quality.  The 2026 Maison Leroy collection will be released soon. Read more about Maison Leroy and browse all current listings

Inspired by a Russian, first made by a Hungarian, who was succeeded by a Frenchman and then a German, the winemaking lineage at Masseto has been decidedly international – until now, that is. Since January 2024, the leading Super Tuscan and Ornellaia’s sibling estate has had its first native at the helm: Marco Balsimelli – born in Arezzo, not far from Siena, took the reins from longtime Production Director Axel Heinz.  Balsimelli comes with his own illustrious pedigree, having long been based in Bordeaux, working at Gruaud Larose and, since 2010, alongside the famous Eric Boissenot as a consultant winemaker to many of the region’s leading estates, but the chance to work at Ornellaia and Masseto – iconic names from his Tuscan homeland – was an opportunity he couldn’t turn down.  It was André Tchelistcheff (the Russian-born Napa winemaker) who first suggested to Lodovico Antinori that a particular hill on the Ornellaia estate would be perfect for Merlot. Tchelistcheff was consulting for Antinori, and recognised the potential of the parcel of blue clay – the same soil that is synonymous with Pétrus. Back then, in the 1980s, Merlot was barely planted in Tuscany and remained an unknown quantity in the region, with only Castello di Ama – based further inland in Chianti Classico – having some vines (today used for its flagship L’Apparita). Nevertheless, the Ornellaia team took a chance and planted most of the seven-hectare swathe of clay in 1984 (additional planting took place in 1995).  The first vintage of Merlot from the site was made in 1987: Masseto was born. The name comes from “masso”, Italian for rock, after the large boulder-like clumps of clay that dot the vineyard’s surface. It didn’t take long for the wine to earn international acclaim, with Wine Spectator giving the 2001 vintage 100 points, and its place was cemented in vinous history.  Although Tchelistcheff consulted until 1989, replaced by Michel Rolland from 1991, Hungarian Tibor Gál was the property’s first winemaker. Gál was succeeded by Thomas Duroux (now of Ch. Palmer), who in 2005 passed the baton to Axel Heinz, the German-born winemaker who preceded Balsimelli. The property has changed hands over the years too, with the Mondavi family taking a share in 1999 before buying it outright from Lodovico Antinori, and selling it onto the Frescobaldi family, who took full ownership of Ornellaia and Masseto from 2005.  Much might have changed, but the terroir hasn’t. “It’s a very special site,” Balsimelli tells me. The all-important clay dominates the topsoil, which is only about a metre deep. When it rains, the clay swells, making it near impossible for the vines’ roots to develop. High sodium levels in the soils only accentuate the problem. “For the roots, it’s a battle every day,” he says. It’s that struggle, he feels, that you can taste in the concentrated, high-acid fruit from the site.  The climate is key too, lying just 10 kilometres from the Tyrrhenian Sea. Fresh marine breezes mean the temperature is around 5°C lower than that in central Tuscany, with a drop of circa 15°C from day to night. Combine this with the light reflected off the sea, and you get a long growing season, preserving aromatics and acidity, yet encouraging phenolic ripeness – wines that combine perfume and power. Surrounded by forest, there is a reason that Masseto is run as an entirely separate project to Ornellaia, with its own unique identity – even if it has always shared a winemaker (and, until 2019, a winery) with its sibling estate.  For Balsimelli, the project has provided a fresh challenge. The shift away from a consultant role – no longer offering advice before moving on to the next project, but sitting with each and every decision – adds a new weight of responsibility. “I spend a lot of time thinking about the technical questions and the consequences,” he tells me. Since most of his work with Boissenot had been based on Bordeaux’s Left Bank, focused on Cabernet-driven blends from larger estates, working with a small property, focused on just one variety and various sub-plots is a different sort of jigsaw puzzle. The approach, for him, is much more Burgundian – all about expressing the purity of the site and its blue clay. “You have to be perfect with only one type of soil and one grape variety,” he explains.  The quest for perfection was started long ago at Masseto and today the vines average between 20 and 30 years in age. They’ve also been moving from cordon-trained to bush vines – first trialled in 2008 and something which they have found helps temper the effects of global warming (coping better in dry conditions and shading the fruit from the heat of the sun). Farmed organically since 2012, there has also been a significant focus on encouraging biodiversity across the site, including using cover crops to reduce soil compaction, increase organic matter and retain humidity in the soils.  Balsimelli’s first vintage was 2024, which won’t be released until 2027. But he’s clearly excited by the site, as well as how he can tweak and improve a wine that is already lauded by critics and consumers. “When you taste old vintages of Masseto, you can feel the legacy, taste the terroir,” he says – and that’s exactly what he wants to do moving forward, channelling the Boissenot philosophy: understanding a piece of land and finding the best solution to express it in the glass. For him, that solution will be all about accentuating the wine’s elegance.  He notes how there was – across the world of wine – a trend towards low yield and high levels of maturity in the early 2000s, but his preferred vintages are those that saw more balance. The 2006, for example, is his favourite at the moment – a year with more rainfall, more vigour, and – he feels – more energy as a result. It’s a vintage that he believes is “the key for the future”.  The site is one that can ripen quickly, and he plans to focus on freshness, maybe picking a little earlier, reducing extraction and lowering temperatures for maceration. The 2022 is the vintage set to be released this September – a wine that Balsimelli notes shows just how good the site is – performing even in tricky conditions such as 2022’s hot growing season. It is, he says, “the magic of Massseto”. Magic it may be, but Balsimelli is set on elevating this special estate even further.   Explore all current listings of Masseto or read more Editorial
