These all-grain recipes are made exclusively from grain without the use of malt extracts. All Grain Beer Recipe Kits differ from malt extract kits or mini mash kits in that the home brewer employs the practice of mashing. Mashing is the process where malted grains are soaked in hot water. The heat activates naturally present enzymes that then convert starch to sugars. You then rinse the sugar out to create your sweet wort.
