What is the key red grape variety in Touraine?

Cabernet Franc is recognized as the key red grape variety in Touraine, which is a significant wine region located in the Loire Valley of France. This region is known for its diverse range of wine styles, with Cabernet Franc thriving in the area's climate and soil conditions. The grape is known for producing aromatic red wines that typically offer flavors of red fruits, herbs, and spices, often with a characteristic light to medium body and moderate tannins.

While Gamay, Cabernet Sauvignon, and Merlot are notable grape varieties globally, they play a lesser role in the Touraine area. Gamay is more closely associated with the Beaujolais region, while Cabernet Sauvignon is primarily linked to warmer regions like Bordeaux. Merlot, although grown in various regions, does not dominate the Touraine landscape in the same way. This specificity of Cabernet Franc to Touraine highlights its significance and regional importance, making it the correct choice for identifying the key red grape of the area.
