Sauvignon Blanc is a white-wine grape from western France, now successfully grown in emerging and established wine regions all over the world. While the grape may be more readily associated with the Loire Valley (for its pivotal role in Sancerre and Pouilly-Fume), it is more likely to have originated from Bordeaux, where it is typically blended with Semillon. In the late 20th Century, a new region began to gain a reputation as one of the great Sauvignon Blanc regions of the world: Marlborough, at the northern tip of New Zealand's South Island. Outside France and New Zealand, the variety has been relatively successful in New World regions such as California, Chile (particularly theCasablanca and San Antonio valleys) and South Africa. Classic Sauvignon Blanc aromas range from grass, nettles, blackcurrant leaf and asparagus to green apples and gooseberries, and to more esoteric notes such as cats' pee and gunflint.
