The two words that best describe Cave Mont Blanc: pristine fragility. Prié Blanc is an uncommon grape and there is very little to compare it to. This wine is from the highest vineyards in Europe. Prié Blanc is the only variety that will grow at altitudes up to 4200 feet (1300 m). Even the pest Phylloxera will not survive this high up, so vines grow on their own rootstock. Grape growing is difficult here and most growers only own a tiny piece of land. 80 growers contribute to the wine, and the co-op is responsible for keeping the wine-making tradition alive. Their devotion to winemaking shows in Cave Mont Blanc, a superior example of dry, sparkling white wine.
