Caymus-Suisun's 2021 Grand Durif is a Petite Sirah from Suisun Valley, in the interior hills east of San Francisco Bay. Petite Sirah (also called Durif) is a dark, thick-skinned varietal that tends toward deep color, firm tannins, and ripe dark fruit flavors. This wine represents a serious expression of the varietal in a region known for growing it with real intensity.
