Content: 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. Your brewing setup, the time and effort you wish to invest in the process, and the flavor profile desired in your beer will determine which form of corn you may wish to use in your recipe. For most beer recipes you will typically want to limit the amount of corn to 30% of the total fermentables. Too much corn can result in some cider or solvent-like flavors in the finished beer, risk incomplete conversion in the mash, and dilute FAN (free amino nitrogen) too low for adequate yeast nutrition. Using more than a pound (0.45 kg) of powdered corn sugar or more than 1.25 cups (296 mL) of corn syrup in a 5-gallon (19-L) batch of beer can lend cidery or solvent-like flavors to the finished beer. More than 3 pounds (1.4 kg) of flaked maize or cornmeal in the mash of a typical 5-gallon (19-L) batch of beer may stretch the enzymatic capacity of the barley malt and result in incomplete conversion of starch to sugar.
