Which region is known for producing quality wines from the Cabernet Sauvignon grape?

The region recognized for producing quality wines from the Cabernet Sauvignon grape is indeed associated with a few renowned areas, but none are directly connected to the options provided. However, among those listed, Rioja in Spain is noteworthy for its production of red wines, which often include some Cabernet Sauvignon in blends, particularly in more modern styles.

Though traditionally known for Tempranillo, some wineries in Rioja have blended Cabernet Sauvignon to enhance complexity and aging potential, which may explain its selection in this question.

Sancerre is primarily famous for white wines made from Sauvignon Blanc, while Bourgogne (Burgundy) is celebrated for its Pinot Noir and Chardonnay, and Chianti is famous for Sangiovese, making those regions less known for Cabernet Sauvignon. Thus, the association with Rioja suggests a broader understanding of wine practices and varietal use, as it is not purely a Cabernet Sauvignon region but does feature it in its diverse offerings.
