<<Disclaimer: Verify this information before applying it to your situation.>> Check out this website: www.sazsbbq.com I live in Milwaukee, WI, where Saz's Restaurant is located. Their BBQ sauce is not only gluten free, but their label says so!!!!! The vinegar is indicated as GF on the label, and the modified food starch is from corn. They will be changing their bottling and labels this summer to indicate this. This is GREAT BBQ SAUCE!!!!! You can order it online at the above website. I have no financial interest in this company. We've just been using their sauce forever, long before we knew what gluten was. It's the beast. We need to applaud their efforts to help us by changing their labels. One way to do this is to try their sauce. I know you'll like it. -Mary, Milwaukee, Wisconsin
