The nature of Collazzi’s soils is sandy and clayey, rich in limestone, consisting of stone, and not excessively fertile. These conditions have led the choice of planting mainly Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot grapes and, only partly, the traditional Sangiovese. This varietal choice, together with the temperate microclimate of the area, allow to obtain charming, fruity and complex wines.
The vineyards, planted at a density of more than 6,000 plants per hectare, use training systems such as the guyot and cordons, with a very reduced load of buds, in order to guarantee grapes of great quality and concentration.
