A: Temperature control is crucial in wine fermentation because it affects yeast health, fermentation speed, and the expression of flavors and aromas. The proper fermentation temperature is dependent on many factors, the most important of which is the style of wine to be produced. Yeast consumes the sugars in the grape juice and converts them into ethanol, carbon dioxide, and other byproducts. It is common to warm the fermenting juice artificially to help this happen. If the fermentation temperature is too cold then the yeast goes dormant and won’t complete the fermentation. Ultimately, this means that to create good wine with the flavors you intend, it is extremely important to control must temperature. Red wine is typically fermented at higher temperatures 20–30 °C (68–86 °F). Fermentation temperature is also crucial.

Temperature plays an extremely vital role in the fermentation process. It is recommended to ferment your EC-1118 between 18°C and 24°C (64°F to 75°F). However, some wines, particularly those with high sugar content, require longer fermentation periods. For example, fermenting at lower temperatures can help preserve the delicate aromas and flavors of white wines, while fermenting at higher temperatures can extract more intense flavors from red grapes. Wild swings of temperature should be avoided. The yeast Saccharomyces cerevisiae synthesises a variety of volatile aroma compounds during wine fermentation. A yeast cell will turn approximately 55% of the sugar it eats into ethyl alcohol, and the remaining 45% into carbon dioxide gas and other byproducts. Once spontaneous malolactic fermentation is initiated, MLF can take several weeks to complete and is essential for developing complex flavors and aromas in In conclusion, yeast is a tiny but mighty player in the wine fermentation process.
