<<Disclaimer: Verify this information before applying it to your situation.>> According to McCormick (1-800-632-5847) all their PURE spices and extracts are GF. To add to that, I learned today that the "Food Service" size is not always the same mixture as as the regular supermarket size. The food service phone # is 1-800-322-7742. The people at both numbers are very helpful, but I would suggest calling on all things you buy in any size. Judy, San Jose,Ca
