If Yeast has access to oxygen (aerobic respiration), it produces: Carbon Dioxide + Water

How does Yeast work?

When Yeast has no oxygen (anaerobic respiration), it produces: Carbon Dioxide + Ethanol

For Alcoholic Beverages (Wine, Beer, Spirits) Yeast is left in bottles or kegs with no oxygen so it produces ethanol (alcohol)

How is Yeast Used?
