Petit Verdot is a variety of red wine grape, principally used in classic Bordeaux blends. It ripens much later than the other varieties in Bordeaux, often too late, so it fell out of favour in its home region. When it does ripen it adds tannin, colour and flavour, in small amounts, to the blend. Petit verdot 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.
Petit Verdot probably predates Cabernet Sauvignon in Bordeaux, but its origins are unclear. There are records of it in the eighteenth century, but its characteristics suggest an origin in much hotter climes than the Gironde.
It is one parent of Tressot, the other parent being Duras, a grape from the upper Tarn valley near Toulouse. It's possible that both were brought to the region by the Romans as they moved inland from the Mediterranean.
Distribution and Wines
Verdot was included in James Busby's collection of 1832, and it was trialled by Sir William Macarthur in the 1840s. In 2000 there were 1600 hectares in Australia with Kingston Estate in South Australia having the largest planting, four times more than in France. It is increasingly being used to make massive, brooding, single varietal wines that will age for several years - Pirramimma has championed this approach and Warrumbungle Wines releases only aged / cellar vintages to highlight the aging potential.
Almost all the Petit Verdot in France is planted in Bordeaux, mostly in the Médoc where it is used in small amounts to give structure to the classic Bordeaux blend. However the late ripening means that in some years the entire crop is lost and it only properly ripens once every four years, so it has fallen out of favour, particularly with the trend towards earlier-maturing wine. Château Palmer is unusual in having up to 6% Petit Verdot in its blend, which helps stiffen the high proportion of Merlot in their wines. 1-3% is more usual.
In Peru, Petit Verdot vines are grown in the southern Ica Region. The desert weather from Ica allows producers to make 100% varietal Petit Verdot wines. "Tacama" winery produces one its high end wines, "Don Manuel" with 100% Petit Verdot grapes. 
The profusion of Meritage Bordeaux blends has seen considerable interest in the variety in California, where there was 360 ha in 2003. The more consistent, warmer climate is a big help in reliably ripening the grape, and producers are starting to experiment with single varietals. It is also planted in a small way in Arizona, Colorado, Texas, Virginia, Missouri, North Carolina, Long Island, New York and Washington.
Vine and Viticulture
The leaves have 3-5 lobes with a distinctively elongated central lobe. The small, cylindrical bunches are winged, with small black berries.
The name Petit Verdot ('small green') refers to one of the main problems with the grape, that often the berries fail to develop properly without the right weather during flowering. It also refers to the late ripening which usually comes too late for the Bordeaux climate. Petit Verdot also has a peculiar characteristic in that it produces more than two clusters per shoot.
