What defines a cereal mash in brewing?

In brewing, a cereal mash is defined by the practice of mashing adjuncts—typically grains other than barley—before they are combined with the main mash of barley. This process allows for the necessary enzymatic activity to convert the starches present in these adjuncts into fermentable sugars. By conducting a cereal mash, brewers can effectively incorporate adjuncts like corn, rice, or wheat, which may require specific temperature and time conditions to properly convert their starches.

This method enhances the overall flavor profile and character of the beer, as each adjunct can contribute distinct flavors and attributes. The successful conversion of adjunct starches is crucial for achieving the desired gravity and flavor in the final product. Thus, the focus on integrating adjuncts at the beginning of the mash process is central to defining a cereal mash.
