Brewing

Brewing is a multi-stage process during which the brewer encourages a grain such as barley to germinate briefly, steeps the grain in water to release its sugars, and adds yeast to the mixture, which ferments the sugar, turning it into alcohol and carbon dioxide. Around the world, people have brewed grains and starchy vegetables for thousands of years from ingredients as varied as rice, corn, cassava, pumpkins, sorghum, and millet, and brewed beverages are staples in the diets of many cultures.
