Tasting notes
From the 3ha Volcanic Hill single vineyard. 100% Cabernet Sauvignon. Fermentation in small, open-top fermenters, followed by a cold soak and gentle extraction of up to 21 days on skins. Aged 20 months in nearly 75% new French Oak and aged one year in bottle before release. Perhaps the darkest and most showy of the wines in 2021 in terms of its aromatics, boasting black plum and blue fruit notes and slatestone, with full-bodied richness, plush, seductive dark-berry fruits, and darker earth mineral character nuanced by grilled herbs. Crisp, ripe tannins are super compact, layering in a solid foundation to support all the ripe, dark fruit character. There's plenty of tension here, too. During my visit in June of 2024, Nicole Carter (president) and winemaker Graham Wehmeier took me on a tour of the property to get an upfront and close look at Diamond Creek's single vineyards (Volcanic Hill, Gravelly Meadow, and Red Rock Terrace). There is a good amount of replanting going on, and as the young vine fruit comes online shortly, much of it will likely get blended into their Three Vineyard Blend as the winery's entry-level bottling. Graham, who joined in 2020, has dialled down the toast levels on the oak and is exploring new cooperages. Suffice it to say, the wines are more expressive of the site than ever, with a freshness factor dialled way up.

The 2021 Cabernet Sauvignon Volcanic Hill is a 313-case blend of 93% Cabernet Sauvignon and 7% Petit Verdot. Scents of crushed stone accent plummy, black cherry fruit on the nose, while the medium to full-bodied palate includes some cooling overtones to the dark fruit. Ripe, silky and long on the finish, it expresses Napa fruit while remaining supremely elegant.
Dark and winey, with steeped red and black currant fruit flavors that rumble through, laced with a prominent iron minerality and a streak of ash, plus wild herb and savory notes. The finish is grippy and long, with lingering hints of singed mesquite and alder. Distinctive and in need of cellaring. Best from 2026 through 2045. 313 cases made.
The 2021 Cabernet Sauvignon Volcanic Hill is one of the very finest wines I have ever tasted at Diamond Creek Vertical and explosive, with tremendous depth, the 2021 screams out of the glass with a complex mélange of dark fruit, violet, lavender, mocha and dried herbs. All of the Volcanic Hill signatures are present, but without any of the excesses of some previous years
