What is the ideal temperature range for malolactic fermentation?

Explanation:
Malolactic fermentation relies on lactic acid bacteria that work best at a middle-range temperature. When the wine is within this moderate warmth, the bacteria are active enough to convert malic acid into lactic acid smoothly, softening the wine and increasing stability. If the temperature is too cool, the bacteria become sluggish and MLF can stall or take a long time to complete. If it’s too warm, they can work too quickly and may produce unwanted flavors such as buttery notes, plus a higher risk of volatile acidity or spoilage. So, a moderate, steady temperature creates ideal conditions for a controlled, complete MLF.
