Abstract
The present invention relates to methods for producing high levels of alcohol during fermentation of plant material, and to the high alcohol beer produced. The method can include fractionating the plant material. The present invention also relates to methods for producing high protein distiller's dried grain from fermentation of plant material, and to the high protein distiller's dried grain produced. The method can include drying a co-product by ring drying, flash drying, or fluid bed drying. The present invention further relates to reduced stack emissions from drying distillation products from the production of ethanol.
