Giancarlo?s uncle, Sergio Tommasi, manages the viticulture at the estate. The five valleys of San Ambrogio, San Pietro in Cariano, Fumane, Marano and Negrar dominate the western, best and Classico-designated part of the region, and are often said to resemble the fingers of a hand. Tommasi?s vineyards are located in two of these valleys: Sant? Ambrogio and San Pietro in Cariano. While they have a very traditional approach in the cellar, Tommasi is considered an innovator in the way they manage their vineyards. Tommasi was one of the first wineries to introduce the guyot method over the more traditional pergola system of vine-training, and their vineyards are planted at very high density, with resulting lower yields and fruit of increased complexity and concentration.
