Rice and corn malt are classified as what type of ingredient?

Rice and corn malt are classified as adjuncts in the brewing process. Adjuncts are ingredients that are added to the main grain bill primarily to enhance certain characteristics of the beer, such as body, mouthfeel, and alcohol content, without serving as the primary source of fermentable sugars.

In brewing, the main ingredients typically include malted barley, which provides the essential sugars needed for fermentation and contributes to the overall flavor and color of the beer. On the other hand, adjuncts like rice and corn are often used to lighten the body and flavor profile, making them popular in the production of lighter beers such as lagers.

These adjuncts do not contribute significant flavor on their own but can affect the final product by influencing the fermentation process or enhancing the beer's crispness. Additionally, they can help lower production costs due to their often cheaper price compared to traditional malted barley.
