This is one of the steps in the winemaking process.

The process can be completed in different types of vats, namely stainless steel, concrete or wood.

There are two different types of fermentation:

  • Alcoholic: alcoholic fermentation allows the yeast to transform sugar into alcohol.
  • Malolactic: the aim of this is to reduce a wine’s acidity, transforming malic acid into lactic acid. In Bordeaux malolactic fermentation is only used for red wines, but in Burgundy it is also used for fine whites.
