Sauvignon Blanc - Climate and Geography

Climate and Geography

The Sauvignon Blanc vine often buds late but ripens early, which allows it to perform well in sunny climates when not exposed to overwhelming heat. In warm regions such as South Africa, Australia and California, the grape flourishes in cooler climate appellations such as the Alexander Valley area. In areas where the vine is subjected to high heat, the grape will quickly become over-ripe and produce wines with dull flavors and flat acidity. Global warming has had an effect on the Sauvignon Blanc grape, with the rising global temperatures causing farmers to harvest the grapes earlier than they have in the past.

The grape originated in France, in the regions of Bordeaux and the Loire Valley. Plantings in California, Australia, Chile and South Africa are also extensive, and Sauvignon Blanc is steadily increasing in popularity as white wine drinkers seek alternatives to Chardonnay. The grape can also be found in Italy and Central Europe.
