Q:

What is the chemical equation for wine fermentation?

A:

Quick Answer

The chemical equation for wine fermentation when starting from glucose is C6H12O6 = 2CO2 + 2CH3CH2OH, and when starting from maltose or sucrose, it is C12H22O11 = 4CO2 + 4CH3CH2OH. In both processes, the products are carbon dioxide and ethyl alcohol. Yeast cells are used in the fermentation process to extract energy from the sugar.
