(WashingtonExaminer) - Have you ever wondered how all of those bubbles actually get into a glass of Champagne? I can assure you it is by very precise design. Champagne is the one of the most highly controlled wine growing regions in the world. Every step from grape to glass is regulated in order to ensure that consumers are getting the best product the region has to offer. There are only three grape varietals that are allowed in Champagne; Chardonnay, Pinot Noir and Pinot Muenier. They must be grown in one of the official 319 Crus. Even the winemaking process, using the M?thode Champenoise, and the labeling are tightly controlled.
