Which grape variety is known for yielding low production but producing highly sought-after wines in Bordeaux?

The grape variety known for yielding low production but producing highly sought-after wines in Bordeaux is Cabernet Sauvignon. This varietal is revered for its ability to create complex and age-worthy wines with intense flavors and rich structures. The low yields of Cabernet Sauvignon contribute to the concentration of flavors and characteristics in the wine, making it extremely desirable among collectors and connoisseurs.

In Bordeaux, second to none in terms of its prominence, Cabernet Sauvignon thrives in the region’s well-drained soils, particularly in the Left Bank appellations like Pauillac and Margaux. Winemakers often utilize careful vineyard management practices, including selecting the best clones and employing techniques that restrict yield, further enhancing the quality of the final product. This grape variety is not only integral to Bordeaux's identity but also commands high prices, especially from prestigious vineyards and vintages.

While other varieties like Merlot and Cabernet Franc play important roles in Bordeaux blends or produce quality wines, they typically do not match the prestigious status and market demand associated with Cabernet Sauvignon. Pinot Noir, while celebrated in regions like Burgundy, doesn't hold the same prominence in Bordeaux.
