Which grape is crossed by Carignan and Cabernet Sauvignon?

Ruby Cabernet is a hybrid grape that results from the crossing of Carignan and Cabernet Sauvignon. This grape was specifically developed to combine desirable traits from both parent varieties. Carignan contributes to the grape’s ability to withstand heat and drought, while Cabernet Sauvignon offers structure, depth of flavor, and aging potential.

Ruby Cabernet is primarily used in California and is valued for its moderate tannins and fruit-forward character, making it approachable early in its life. This hybridization was part of a broader effort to create grapes that adapt well to various growing conditions while also delivering consumer-friendly wines.

The other options listed do not accurately represent the cross of Carignan and Cabernet Sauvignon. Petit Sirah, Malbec, and Sangiovese are separate grape varieties with distinct lineage and characteristics, making them irrelevant in the context of this specific question about Ruby Cabernet.
