Ancient vine, can be identified with the Biturica strain. Plinio and Columella mention Biturica referring to the great wines elaborated by the Bituriges Vibisci, Gironde tribe. And the Gironde district has to be considered the homeland of this noble variety that represents the universality of viticulture. It is well adapted to Australia, South Africa, Chile, California and Lebanon. In Italy it has found diffusion in the North: it is assumed that Count Manfredo of Samuy in 1820 introduced the vine directly from France cultivating it in the vineyard of Valmagra at Alexandria, driven by the resemblance between its lands and those of Médoc And the Gironde. Certainly, instead, an extensive Cabernet vineyard rises around 1870 on the Euganean Hills in the province of Padova.
Recently introduced in Oltrepò, Cabernet Sauvignon is a vine of medium vigor, with constant production. It requires climates temperate or, however, tendentially dry or ventilated. It gives excellent results if grown on well-exposed terrains, stony or clayey and well drained in the plain. It does not accept soils that are fertile and humid, which will induce the plant to weak lignification. It adapts to different forms of growth and pruning.
