The Brewing Process and Carbohydrate Chemistry

Basics of Malting, Mashing, and Fermentation

The process of brewing involves malting, kilning, mashing, and fermentation to convert barley starches into reducing sugars and eventually ethanol and carbon dioxide.

  • kilning

  • amylase enzymes
  • alpha amylase
  • beta amylase
  • amylopectin
  • glycosidic linkages
  • fermentation
  • glucose
  • carbon dioxide
  • spectrophotometer
