A beer or brewing adjunct is any unmalted grain or other fermentable ingredient used in the brewing process.

 

Brewing adjuncts are often used with the intention of lowering overall brewing production costs or modifying aspects of the beer such as creating better head retention or enhancing the flavor of the beer.

 

Some common brewing adjuncts include rice, corn, sorghum, rye, oats, honey, fruits, and candi sugars.
