Which red wine varietal is nicknamed the "King of Grapes"?

Cabernet Sauvignon is the red wine varietal nicknamed the “King of Grapes.” The title reflects its worldwide reputation, historical importance, ability to produce age-worthy wines, and success in many different wine regions.

The variety originated in Bordeaux, France, where it remains a foundational grape in classic red blends. It is usually combined with Merlot, Cabernet Franc, Petit Verdot, and other grapes to create Bordeaux-style wines. Cabernet Sauvignon is also central to the wines of Napa Valley, California, and is widely planted in Australia, Chile, South Africa, Italy, and Washington State.

Cabernet Sauvignon typically produces deeply colored wines with firm tannins, noticeable acidity, and flavors that can include blackcurrant, blackberry, cedar, tobacco, and mint. Oak aging often adds vanilla, spice, or toast. The nickname is sometimes phrased as “king of red wines” or “the wine of kings,” but it points to the same grape. Merlot is softer and more immediately approachable, while Pinot Noir is often called the “queen” of grapes.
