What are the main red grape varieties?
Quick answer
The world's leading red grape varieties are Cabernet Sauvignon (most widely planted), Merlot, Tempranillo, Grenache (Garnacha), Syrah (Shiraz), Pinot Noir, Sangiovese, Malbec, Nebbiolo and Cabernet Franc. Each has a distinct flavour profile and structure.
Detailed answer
Red grape varieties form the backbone of the world's great wines. While over 1,300 red varieties exist, a handful dominate global production.
Cabernet Sauvignon is the world's most planted red grape (roughly 340,000 hectares). Born in Bordeaux, it thrives in warm and temperate climates, producing tannic, structured wines with blackcurrant, cedar and green pepper aromas and outstanding ageing potential.
Merlot, the second most planted (about 266,000 ha), is Cabernet's blending partner in Bordeaux. Softer and fruitier (plum, cherry, chocolate), it also shines as a single variety on Bordeaux's Right Bank and in Chile.
Tempranillo dominates Spain (Rioja, Ribera del Duero). Grenache/Garnacha is the quintessential Mediterranean grape (Châteauneuf-du-Pape, Priorat). Syrah/Shiraz excels in the northern Rhône and Australia. Pinot Noir — the most demanding variety to grow — produces the most elegant reds (Burgundy, Champagne, Oregon).
Sangiovese is the soul of Tuscany (Chianti, Brunello). Malbec, originally from southwest France (Cahors), found its most famous expression in Argentina. Nebbiolo produces the majestic Barolo and Barbaresco of Piedmont.
