Gluten is a protein found in wheat, barley, rye, oats and various other sources I can't remember at the moment. My wife has a gluten intolerance and therefore cannot drink beer anymore. Its been close to 5 years since she has had a brew. Has anyone ever made any beer with anything besides barley. Is this possible? Neither of us are really cider fans so I am not really looking for something like that. My wife suggested I try buckwheat which does not contain the gluten protein. Has anyone ever tried this? I don't know if there is enough sugars in buckwheat for it to work like regular barley does. Any thoughts would help, as I am determined to make her a tasty beer or beer like beverage she can drink.
