($24, Pasternak Wine Imports):  Anyone who wants a lesson in the French concept of terroir–the notion that where the grapes grow determines the nature of the wine–should taste this Sancerre and Saget’s 2008 La Petite Perrière (also reviewed this week) side by side.   Both are made entirely from Sauvignon Blanc, but this Sancerre has an alluring chalky minerality, especially in the finish, that is characteristic of the appellation, balances the pungency of the varietal and adds complexity. 90 Michael Apstein Dec 28, 2010
