Cabernet Sauvignon is often called the "king of red grapes" and is the most widely planted red wine variety in the world. A natural cross between Cabernet Franc and Sauvignon Blanc, it emerged in 17th-century Bordeaux and has since conquered every major wine region.
The grape produces deeply colored, full-bodied wines with firm tannins and excellent aging potential. Its thick skin contributes intense colour, tannin structure, and resistance to rot. In cool climates, it shows herbaceous, green bell pepper notes; in warmer regions, it develops riper blackcurrant and plum characters.
Cabernet Sauvignon is the backbone of Bordeaux's Left Bank blends and has found exceptional expressions in Napa Valley, Coonawarra, and Chile's Maipo Valley. It responds beautifully to oak aging, gaining complexity with notes of cedar, tobacco, and vanilla.
Typical colour: Deep ruby to purple core with garnet rim
Young wines show intense purple-black hues. With age, the colour evolves from ruby to garnet and eventually brick-brown at the rim.
Bordeaux typically 12.5-14%, Napa Valley often 14-15.5%, cooler regions like Coonawarra 13-14%
On the nose, Cabernet Sauvignon is immediately recognisable by its intense cassis (blackcurrant) character, often joined by blackberry, black cherry, and plum. Cedar, tobacco leaf, and graphite emerge with age, while younger wines may show green bell pepper (pyrazines) if from cooler climates. Oak ageing contributes vanilla, sweet spice, and sometimes coconut. In top examples, you may detect violet, eucalyptus, or mint, particularly in warmer New World expressions.
The palate is defined by Cabernet Sauvignon's powerful structure—firm, gripping tannins that frame concentrated dark fruit flavours. The hallmark cassis carries through from the nose, joined by dark chocolate, espresso, and savoury notes of herbs and tobacco. Acidity is typically moderate to high, providing freshness and ageing potential. The finish is long and often slightly austere in youth, with persistent tannins and a mineral, graphite quality. Well-made examples reward decades of cellaring, developing extraordinary complexity and silky texture.

Understanding regional style differences helps identify origin in blind tasting.
Look for green/herbal notes and firm tannins for Old World; obvious ripeness, sweetness on the nose, and soft tannins suggest New World. Alcohol heat is often a giveaway for warm-climate New World.

These grapes are commonly confused with Cabernet Sauvignon in blind tasting. Here's how to tell them apart:
Why confused: Both Bordeaux varieties with dark fruit character and often blended together. Both Bordeaux varieties with similar colour depth.
Why confused: Both have green bell pepper notes and dark colour. Both can show green pepper and dark colour.
Why confused: Parent grape with similar name and herbaceous character. Parent grape with similar name and structure.
Colour: Deep, opaque ruby-purple in youth; garnet rim with age.
Key markers: Look for the signature blackcurrant/cassis note – this is almost diagnostic. Cedar and graphite are classic Bordeaux tells. Green bell pepper indicates cooler climate or underripe fruit.
Structure: High tannins that are often grippy in youth. Medium-high acidity. Full body with intense concentration.
Common confusions: Merlot (softer tannins, plum vs cassis), Carménère (more herbaceous, green pepper dominant).
