What are the 5 blending grapes of Bordeaux?

Bordeaux, renowned for its red blends, incorporates five key grape varieties: Cabernet Sauvignon, which gives the structure and longevity; Merlot, which provides roundness and fruitiness; Cabernet Franc, adding aromatic complexity; Petit Verdot, improving color and tannin; and Malbec, giving depth and richness, though it is less utilized now. All these grapes, distinct in taste, are ingeniously blended to produce the wines that this region is famous for.
