Fermentation 
The process that turns grapes into wine. It is the metabolization of the sugars by the yeast, into alcohol, carbon dioxide and heat.

Fined 
A winemaking process to remove small particles from the wine in order to clarify it. Some vintners believe that this removes some flavor and body from the wine, and therefore do not use the technique. Their bottles may be labeled as “unfined” or “unfiltered.”
