Two paths for fermentation ingredients to secure sugar
Ingredients that already contain sugar, such as fruit, honey, and milk, are fermented directly by yeast, while grains like rice or barley undergo a saccharification stage that converts starch into sugar before fermentation.
Fermentation raw materials

Yeast added directly
No additional steps
Saccharification step required
Amylase/Aspergillus
Starch → sugar conversion
Alcohol fermentation
Ethanol + carbon dioxide production
