The Petit Verdot is a red wine grape varietal - believed to have its origins in Bordeaux in France. It is one of the six approved grapes for making red wines in the Bordeaux region. Petit Verdot is thought to have been in the Medoc area well before Cabernet Sauvignon and probably more widely grown. Today - Petit Verdot is the least grown of the Bordeaux red grape varietals.
Typically used as you would a spice in cooking, because a little goes a long way. Petit Verdot will often be blended as little as 1% - 5% of the total wine in order to take advantage of some of its most dominant characteristics. Petit Verdot has a deep purple colour and a strong tannin structure - so used to impart these features to the final wine into which it is blended.

 

Because Petit Verdot tends to ripen late in the growing season and is often lost to rains during harvest time, it is following another red varietal Carménère, into near extinction in the Bordeaux wine region. The name Petit Verdot means 'little green', a reference to the difficulties of growing and ripening this varietal.
When it does ripen, when added in small amounts, it does add excellent, complimentary tannin, colour and flavour to the other red varietals in 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. Planted in suitable climes and properly cultivated, the fruit develops in relatively small winged clusters, loosely filled with round, dark red-to-black, relatively thick-skinned berries.
Petit Verdot's reluctant cooperation in the vineyard is likely why it is not more prevalent. The aroma of Petit Verdot includes cigar box, smoke, leather and earthy tones. In addition to violet and leather, Petit Verdot flavours can include peppers, spices, smoke and herbs.
Petit Verdot is not recommended for those who enjoy a fruit driven wine: plus long aging in oak barrels can also fade its fruit flavours. Petit Verdot is also grown in Italy, Spain, California, Australia, Chile and Argentina with good success, and also selected sites on Waiheke Island in New Zealand.
