The marine influence is key to the success of the Masseto site, with cool sea breezes and a magnified intensity of light, especially towards the end of day. The vineyard’s blue clay soils – having similar properties to the (different) blue clay of Pomerol – provide the perfect balance of heat intensity by day and cooling influences at night to produce a wine with both power and elegance. The clay soils have good water-holding capacity, reducing vigour in wetter conditions, and providing a slow supply of water in drier weather. They also have a high salt content which restricts vigour. The fluctuation between hot days and cool nights preserves acidity, while giving the wines great concentration and ripeness.
The seven-hectare vineyard is made up of three parcels: Masseto Centrale (the original site located on blue clay) provides power, density and concentration of tannins; Masseto Alto produces more structure, rigidity and linearity; while the most recently planted site lower down the slope has a simpler, lighter profile that can soften the potentially angular wines from the main site. The three parcels complement each other to produce wines of balance and consistency. Since 2012, the vineyards have been farmed organically.
