Petit Verdot is a variety of red wine grapes, principally used in classic Bordeaux blends. It ripens much later than the other varieties in Bordeaux, often too late, so it fell out of favor in its home region. When it does ripen, it is added in small amounts to add tannin, color, and flavor to the blend. It has attracted attention among winemakers in the New World, where it ripens more reliably and has been made into single varietal wine. It is also useful in ‘stiffening’ the mid palate of Cabernet Sauvignon blends.

When young its aromas have been likened to banana and pencil shavings. Strong tones of violet and leather develop as it matures.
