Cabernet sauvignon is indeed a red grape variety that is often used in red blends. It is considered by many wine lovers to be the king of hearty reds, and for good reason. The grape itself is known for producing wines that are full-bodied, rich in flavor, and have a great aging potential.
Originally from the Bordeaux region of France, cabernet sauvignon is most commonly blended with other grape varieties such as merlot, cabernet franc, and petit verdot. These blends are often referred to as Bordeaux blends or, more specifically, Left Bank blends, as they are typically made on the left bank of the Gironde River in Bordeaux.
One of the reasons why cabernet sauvignon is often blended with other grapes is because it has high tannins and can be quite intense on its own. By blending it with other varieties, winemakers can round out the wine, soften the tannins, and add complexity and depth.
In Bordeaux, cabernet sauvignon is typically the dominant grape in the blend, with merlot playing a supporting role. Merlot brings a softer, fruitier character to the wine, balancing out the tannins and adding a touch of elegance. Cabernet franc and petit verdot are often used in smaller proportions to add additional layers of complexity and structure.
Outside of Bordeaux, cabernet sauvignon is also widely grown and used in red blends in other regions around the world. In California, for example, it is a key component of the famous Bordeaux-style blends from Napa Valley. These wines often showcase the bold and ripe fruit flavors that are characteristic of the region.
I have had the pleasure of tasting many cabernet sauvignon blends throughout my career as a sommelier. One of my most memorable experiences was a blend from the Napa Valley, where cabernet sauvignon was blended with a small amount of petit verdot and cabernet franc. The wine had intense aromas of blackberries, cassis, and vanilla, with a velvety texture and a long, lingering finish. It was a perfect example of how the blending of different grape varieties can create a harmonious and complex wine.
While cabernet sauvignon can certainly be enjoyed on its own, it is often used in red blends to add structure, complexity, and balance. Whether it's a Bordeaux blend or a New World creation, cabernet sauvignon can play a starring role or be part of a supporting cast, showcasing its bold flavors and aging potential.
