Cabernet Sauvignon is probably the most famous red wine grape variety on Earth. It is rivaled in this regard only by its Bordeaux stablemate Merlot, and its opposite number in Burgundy, Pinot Noir. From its origins in Bordeaux, Cabernet has successfully spread to almost every winegrowing country in the world. It is now the key grape variety in many first-rate New World wine regions, most notably Napa Valley, Coonawarra and Maipo Valley. Wherever they come from, Cabernet Sauvignon wines always seem to demonstrate a handful of common character traits: deep color, good tannin structure, moderate acidity and aromas of blackcurrant, tomato leaf, dark spices and cedarwood.
