Sparkling wine

The visual evidence for sparkling wine is the effervescence of bubbles when opened and poured, and the mousseux on the palate. We differentiate between various production methods, such as the fermentation in the bottle (classic method), the transvasement method (filtering off the lees) and tank fermentation (Méthode Charmat). Slightly sparkling wine is usually produced by impregnating carbon dioxide. In Austria, the production of Sekt as a quality sparkling wine is very important, and the term Hauersekt (vintner's Sekt) is protected for Austrian use.
