What Is a carbohydrate used in beverage brewing?

In beverage brewing, particularly in beer production, malted grains are a primary source of carbohydrates. These grains, such as barley, are processed to convert their starches into fermentable sugars during mashing. The resulting sugars serve as the primary food source for yeast during fermentation, leading to the production of alcohol and carbonation in the final beverage. Additionally, other carbohydrates like corn or rice can be used to adjust flavor and body in certain beer styles.
