The highest part, on the south-eastern side of the Canalotto valley, at an altitude between 532 and 585 meters, has been reserved for Cabernet Sauvignon. The soil is made up of sands and sandstones with variable grain, the texture is partly clayey and calcareous, with a slightly alkaline pH (8.3). It is a moderately deep soil, where the development of the root system of the vine is abundant in the first 60 centimeters and more moderate up to a depth of one meter. It has a normal content of organic matter and is rich in mineral salts such as magnesium and potassium, while it is poor in phosphorus. The vines were planted at a sixth of 2.60 by 1.1 meters (3,490 plants per hectare). The training system is the espalier, with short spurred cordon pruning. Cabernet Sauvignon is a late variety with a very long vegetative period. The grape harvest, carried out by hand by expert winemakers able to select the bunches already in the vineyard, takes place on average between mid-September and the first ten days of October.
