Q-Tip: Sancerre

I took a wine class last night and learned that Sancerre is 100% Sauvignon Blanc. Sancerre is a village in France and their forte, the only grape they really grow for white wines, is Sauvignon Blanc. French wines don't list the grape varietal on the bottle, they just expect you to know who uses what grape since they've been in the business for 400 years.
