Winemakers elsewhere tried to cash in on the champagne boom… In Burgundy, there was a sparkling Nuits St George, a sparkling Montrachet, and a sparkling Romanée Conti. In Bordeaux, there was a sparkling Sauternes. In the Southern Rhone, one winemaker produced a sparkling Chateauneuf du Pape. Aside from their fizziness, however, they bore no resemblance to genuine champagne. “They are miserable parodies,” one critic said.
Champagne had become unique.
