The following is about the brewing term; adjunct is also a term used in linguistics.

---

In beer making and homebrewing, an adjunct is an ingredient other than water, barley, hops, and yeast. Typically, adjuncts are used by beer companies to reduce production costs and meet a taste profile exemplified by most North American lagers. Corn and rice are common adjuncts; Anheuser-Busch is the largest North American buyer of U.S. rice.

Less typically, fruit, spices, honey, and wheat are used as flavoring adjuncts.
