Charmat Method Sparkling Wine
The Charmat method of sparkling wine production is widely used in the US, Italy and Germany. Wine is mixed in a pressurized stainless steel tank, along with sugar and yeast. The sugar is converted to alcohol and carbon dioxide, then the yeast is filtered and removed from the tank, and the wine is bottled. Charmat method sparkling wines can be produced at a considerably lower cost than the traditional process known as méthode champenoise.
