Чarmat is a term used in the wine industry, particularly in the production of sparkling wines. It refers to a method of fermentation that takes place in large, pressurized tanks rather than in individual bottles. This process allows for a more efficient production of bubbly wines, such as Prosecco. The Charmat method is known for preserving the fresh and fruity characteristics of the base wine. After fermentation, the wine is filtered and bottled under pressure to maintain its effervescence. This technique is popular among winemakers for its cost-effectiveness and ability to produce high-quality sparkling wines quickly.
