Cabernet Sauvignon is the most widely planted and significant among the five dominant varieties in the Medoc district of France's Bordeaux region, as well as the most successful red wine produced in California.

Cabernet sauvignon berries are small, spherical with black, thick and very tough skin. This toughness makes the grapes fairly resistant to disease and spoilage and able to withstand some autumn rains with little damage.

It makes the most dependable candidate for aging, more often improving into a truly great wine than any other single varietal. With age, its distinctive black currant aroma can develop bouquet nuances of cedar, violets, leather, or cigar box and its typically tannic edge may soften and smooth considerably.
