SYSTEMS AND METHODS FOR MAKING SPENT GRAIN DOUGH-BASED PRODUCTS

A method for processing spent grain generated as a by-product in an alcoholic beverage making process, the method comprising: a. producing in a mashing process, a mash grain product comprising a mixture of at least one type of grain and a liquid; b. rinsing the mash grain product with a heated liquid to extract sugars from the grain, resulting in a wort mixture for use in the production of alcoholic beverages, and spent grain; c. separating the wort mixture from the spent grain; d. rinsing the spent grain with a cool liquid to cool the spent grain during the separating process by bringing the spent grain into thermal conductive contact with a liquid, the liquid being at a temperature substantially below the spent grain temperature and e. storing the spent grain for use in further processing to make a spent grain food product.
