Black grape variety cultivated in Apulia
Wine grape variety, of important national and international diffusion, present also in Apulia, where it is among the suitable varieties in the whole region.
The wine variety Cabernet Sauvignon n. comes from Bordeaux, region of the South-West of France. It was described in detail in 1785 by Secondat, son of Montesquieu, as a “perfect vine”.
In Italy it reached Piedmont at the beginning of the nineteenth century. In 1870, on the Euganean Hills, there was an extensive vineyard of Cabernets (Cabernet Franc and Cabernet Sauvignon).
Research carried out with the study of DNA (Bowers J.E. and Meredith C.P., 1997) using 30 microsatellite loci, demonstrated the relationship of direct kinship between Cabernet franc and Cabernet sauvignon, with the latter which is the result of the crossing between Cabernet franc and Sauvignon blanc.

The Cabernet Sauvignon n. vine is used exclusively for vinification. Vinified as a single variety, the wine may lack complexity, while it gives its best in blends with other varieties, with excellent results even with indigenous varieties from Apulia. It produces great wines for ageing, showing elegance and aroma. In Apulia it is used for the production of the QWpsr Castel del Monte wine.
The wine is deep ruby red in colour, full-bodied and alcoholic, sometimes tannic and hard, but improving after ageing. Following this, the wine’s aroma, the characteristic herbaceous flavour of green pepper, less intense than in Cabernet franc, changes towards more pleasant and complex aromas, with notes of violet.
The Cabernet Sauvignon vine is one of the most widespread in the world. It is practically present throughout Italy and therefore also in Apulia, where it is registered among the varieties suitable for cultivation throughout its territory.
