<<Disclaimer: Verify this information before applying it to your situation.>> To my knowledge, quinoa is not a gluten-containing grain. See the attached web-site. You'll see that CSA has it on it's safe list: http://www.celiac.com/forbiden.html They used to note that you need to be cautious of cross-contamination. I buy my bread mix from Sylvan Border Farm. It has quinoa and amaranth. They sell it as a gluten-free product. A couple of people that work there have celiac.
