What is the predominant grape variety in Bordeaux's left bank?

The predominant grape variety in Bordeaux's left bank is Cabernet Sauvignon. This region is characterized by its gravelly soils, which are well-suited for growing Cabernet Sauvignon, allowing the grapes to produce wines that are rich in tannins and acidity. These characteristics are essential for creating complex, age-worthy wines that are often blended with other varieties such as Merlot and Cabernet Franc, but Cabernet Sauvignon remains the backbone of many prestigious Bordeaux wines, including those from the Médoc and Haut-Médoc.

Additionally, Cabernet Sauvignon contributes to the distinctive flavor profile of left bank Bordeaux wines, which often exhibit dark fruit flavors, herbal notes, and a certain minerality attributable to the region's terroir. Its ability to thrive in the climate of this area, coupled with its capacity for aging, solidifies its status as the dominant variety on the left bank of Bordeaux.
