Maize (corn) is a cereal grain that can be used as an adjunct in beer. High additions contribute or corn or "popcorn" character.[1]

Corn starch gelatinizes at (73-79°C vs 60-75°C ?). However, corn flakes and corn meal are typically gelatinized during production and can be added to a mash without further pre-treatment.[2][3] The extract content from corn is about the same as for barley malt.

Corn contains a lot of oil that is typically removed during processing to produce flakes or grits.[3][4]

Raw/ungelatinized corn requires a cereal mash. Since the typical gelatinization temp is 70-75°C, 10% malt at 78°C is sufficient to liquefy maize starch. Higher temperatures result in lower extraction since retrogradation takes place if there starch is not liquefied by enzymes (alpha-amylase).[4]

Corn gives beer a full clean flavor.[5]
