Flavoring Beer: Get the most from additions

Content: Of the various forms of corn that are the most practical for you to use in a brew, cornmeal/grits, flaked maize, and corn sugar (powder or syrup) are the most practical forms for homebrewers to use. Each of these three forms of corn require different treatment and each will result in a somewhat different flavor, body and clarity in the finished beer. In order for yeast to be able to ferment what ends up in wort, those ingredients must be in the form of sugars. To make corn fermentable, the starch it contains must first be gelatinized by being cooked in water between 158–167 °F (62–75 °C) or higher for about 30 minutes. Since we want to be certain that gelatinization is complete, the simplest way to do this is to cook the corn addition in boiling water. After gelatinization is complete, the starch can then be converted to sugar by amylase enzymes in the mash. As you can see, some forms of corn require extra preparation for brewing and some can go right into the kettle as is. In the case of corn sugar, starch gelatinization and conversion of starch to sugar has already been taken care of and the sugar can simply be added as corn sugar in powdered form or as syrup directly into the wort. Flaked maize is made by steaming and pressing (thus gelatinizing and drying) corn through hot rollers, and thus can be added to the barley malt mash where the enzymes that convert the starch in the barley malt will also convert the starch in the flaked maize. Corn grits or cornmeal must first be cooked in water until the starch is gelatinized before they can be added to the barley malt mash for conversion to sugar.
