<<Disclaimer: Verify this information before applying it to your situation.>> After my post stating these were 100% GF I received an e-mail from someone stating they had checked them out earlier this year and they were told they were not GF anymore. I e-mailed the company back and this is what I got in response: Amy, I just spoke with our plant manager and he reassured me that we are gluten free. The determining ingredient is the vinegar. We use an 'apple' vinegar and not one derived from a grain. I don't know who your friend talked to but we are gluten free. Thanks again for your inquiry Denny Leland Cookies Food Products Just wanted to let people know! Amy in Iowa
