How do you prevent malolactic fermentation in wine?

How do you prevent malolactic fermentation in wine?

Malolactic fermentation can only occur at temperatures higher than 68 degrees Fahrenheit, so keeping wine cold is one way of preventing malolactic fermentation. Another method is early racking; malolactic fermentation requires a specific pH and won't work with wines that have a very low pH (below 3.1).

What does malic acid do to wine?

Malic Acid is one of the main acids found in the acidity of grapes. Its concentration decreases the more a grape ripens. Malic Acid provides a strong link to wines tasting 'flat' if there is not enough. If there is too much the wine will taste 'sour'.
