Cabernet Sauvignon is one of the world’s most renowned red grape varieties, originating in Bordeaux and now grown in nearly all major wine regions. It is a hardy, late-ripening vine that produces small, thick-skinned berries in compact clusters, giving naturally high tannins and deep color. The variety performs best in warm, well-drained sites where it can achieve full phenolic ripeness, though it is adaptable to a range of climates. Cabernet Sauvignon wines are typically deep ruby to nearly opaque, with firm tannins, moderate acidity, and classic notes of dark fruit, cedar, and spice. Styles span from structured, age-worthy bottlings to more approachable, fruit-forward expressions depending on climate and winemaking choices.
