A very respectable sparkler of 100% Chardonnay. That's why it's called Blanc de Blancs, "a white wine from white grapes." And since it's not from the Champagne region, it has to be labeled Vin Mousseux ("sparkling wine") as well as Brut ("dry"). It's made by Caves de Wissembourg, a very respectable producer of prize-winning sparklers that are distributed throughout Europe. So treat yourself to "Champagne" on a beer budget...and let the bubbles flow.
