Prosecco

This sparkling awesomeness is named after a white grape from the Veneto region of northeast Italy. Prosecco gets its carbonation by fermenting in batches in large, sealed containers—slightly different from Champagne, but pretty close. It is often sweetened to a higher level than Brut Champagne in the finishing stage, and does not age the way Champagne does. On average it's less expensive than Champagne, and should be drank fairly soon after its creation. A cheaper wine is just that, so it does take a knee when you start comparing it to vintage Champagnes on scales of depth and complexity.
