<<Disclaimer: Verify this information before applying it to your situation.>> I had one response regarding my question on brewers yeast. (D. Buckmann) [There is no such thing as gluten free brewer's yeast. However, we can use nutritional yeast which many nutritional and health food stores (HFS) seem to like to label as "brewer's yeast." This of course is a misnomer. The kind you want is made by Red Star, and they guarantee their yeast products to be gluten free! I believe that Red Star makes both the powdered and a flaked form of nutritional yeast. I found out that my HFS follows the horrible practice of repackaging and mislabeling, but they were kind enough to show me the bag it came from and it was Red Star Nutritional on the bag label. BTW, I have contacted Red Star for the gf status.]
