Cabernet Sauvignon

A flagship variety of Bordeaux (F), Cabernet Sauvignon is one of the most commonly grown grapes in the world. The unexpected discovery of its heritage in 1997 was big news: it's a natural cross between Cabernet Franc and Sauvignon Blanc, which probably took place in Gironde before the 18th century. This makes it a half-sibling of Merlot and Carmenère. In Switzerland, this variety prone to fungal disease is grown essentially for making Bordeaux blends (with Cabernet Franc and Merlot), adding notes of blackcurrants and blackberries.
