This is a short how-to on how I process spent beer grains from home-brewing beer into a healthful, tasty, and inexpensive ingredient I can use in bread, cornbread, stews, and even cakes and cookies. I buy and use grains for making beer, so this product is essentially free, as well as full of delicious sugars, calories, and digestible fiber. You will need a food processor and a food dehydrator to do this properly, although your oven might substitute for the dehydrator in a pinch.
Step 1: Getting your Grains
The spent grains will initially look like this, wet from the beer-brewing process. I have had good success freezing them immediately after brewing for future reference, but this adds another step to the process since you must first warm the grains to room temperature before processing them further. For a few pounds of grain frozen into a block the warming step involves leaving them on a cookie sheet at room temperature for a day or so.
