To better learn how climate affects the acidity, alcohol, aroma, sweetness, and body of Sauvignon Blanc, start first with a Pouilly-Fumé as your benchmark. Then try a Sauvignon Blanc from Marlborough, New Zealand which is similar in coolness to the Loire Valley. Now return to a more temperate climate in France to try a Graves, a dry white Bordeaux, made from 100% Sauvignon. Last but not least, sample a Fumé Blanc from California.
By the way, did you know that Fumé Blanc is a totally made-up name for Sauvignon Blanc? Robert Mondavi coined the name to increase the acceptance and popularity of Sauvignon Blanc in the US in the late 60’s.
