If a customer wants to pair a red wine with a fish dish, which wine would be the best recommendation?

When considering the best red wine to pair with a fish dish, the most suitable recommendation is Beaujolais. Beaujolais, particularly those made from the Gamay grape, is known for its light-bodied, fruity profile and lower tannin levels. This characteristic makes it more harmonious with the delicate flavors and textures often found in seafood. The wine's acidity can also complement the dish, enhancing the overall dining experience without overpowering the fish.

While Cabernet Sauvignon is typically rich and full-bodied, it may clash with the lighter flavors of fish. Pinot Noir, although more versatile than Cabernets, can sometimes be too heavy for certain fish dishes, depending on their preparation. Merlot tends to have a softer profile but still carries a level of richness that might not match as well with lighter fish types. Beaujolais stands out as the most balanced choice, making it ideal for pairing with a variety of fish dishes.
