For a long time I thought that Fumé Blanc was a grape. After all, it appears every now and then on a bottle of California white wine in the same section as bottles with Chardonnay and Sauvignon Blanc on the label. I figured it was some obscure grape that only a few vineyards grew which is why I did not see it very often. Well, there is no such grape. Fumé Blanc is actually Sauvignon Blanc under another name.
