Primary Fermentation
Primary fermentation creates wine’s alcohol.
Primary fermentation takes roughly ten to thirty days, depending on how alcoholic the wine should become.
Longer fermentation leads to drier wines because the vast majority of sugars were converted into alcohol, while shorter fermentation usually leads to naturally sweeter wines.
Leftover sugar is referred to as residual sugar. Microscopic yeast, seeming like powder on the grape’s skin, performs fermentation anaerobically (without oxygen) and converts grapes’ sugars and natural acids into alcohol and carbon dioxide.
Yeast fall to the bottom of the fermentation vessels as sediments when finished converting the glucose.
Most winemakers, nonetheless, may add yeast because the natural yeast found can vary. For every one gram of sugar, half a gram of alcohol is created; therefore, if the sugar content is low but the intended alcohol content is high, winemakers add more sugar, a practice referred to as chaptalization.
The must weight (showing the must’s sugar content)—needed to confirm the amount of sugars in the wine—is vital in guiding the winemaker on how much more time fermenting the wine needs.
Organic Acids in Grapes
Three essential organic acids are found in grapes: citric acid, malic acid, and tartaric acid. Citric acid disappears quickly in the fermentation process, malic acids are converted to lactic acids, a ... read more

Malolactic Fermentation
Malolactic fermentation takes place in select red and white wines when certain strains of bacteria are added in addition to the few that are already present. This process turns harsher malic acid ... read more
