Sparkling wine contains significant levels of carbon dioxide making them fizzy. The bubbles are created using one of the following general methods:
1. “Traditional Method” here 2nd fermentation takes place in bottle where sugars and yeasts are added forming smaller bubbles (as in Champagne & Cava) or,
2. “Tank Method” where 2nd fermentation takes place in steel tank producing larger bubbles, the process accelerated by CO2 injection for cheaper wines (as in Prosecco). Either way, not just for celebrating and toasting, enjoy anytime!
