My WOTY was a Drapier Champagne, NV, consumed with lunch in Paris. 100% Pinot Noir. Said to be the favorite of Charles DeGaulle, or at least that is what the waiter said.
Also, a 1995 Charles Heidsieck, courtesy of Purple Haze was really terrific. A Gosset Grand Millesime Brut from 2006 was wonderful.
