Starting from the 1990’s, Collazzi’s vineyards and cellar have been radically upgraded, with the objective of producing excellent wines, of unique personality, and with a different style from the one typical of this area.
The restructuring of the production facilities has been conducted by Lamberto Frescobaldi, who is also responsible for the wine making.
The nature of Collazzi’s soils is not particularly fertile: sandy and clay, rich in limestone, with an abundantly rocky texture, it has led to the choice of planting grapes of Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot, and only small amounts of the more traditional Sangiovese. This varietal mix, together with the area’s temperate microclimate, allows the production of supple, fruity and complex wines.
The vineyards, planted with a density of over 6,150 plants per hectare, are grown either with the spurred pruned cordon or the Guyot trellising system, leaving only a very low number of buds to each cane, to produce grapes of great quality and concentration.
