<<Disclaimer: Verify this information before applying it to your situation.>> Hi, Yesterday I talked to a representative at Penzeys spices (414) 679-7207. She informed me that out of the over 250 herbs, spices and spice blends that they carry (catalogue available on request), only one (the Taco seasoning) contains gluten. They grind all their own spices except Sumac (which is ground by another company with added salt) and make all their own blends. They never use any agent to facilitate easier grinding, never dust the conveyor belts with starch of any kind, and add no anti caking, or free flow agents to any herb spice or blend. This is great news for Celiacs! I have no affiliation with this company, but I have ordered many spices from them and am a very satisfied customer. As an added bonus their prices are very reasonable, lower than most supermarket brands, and the products are very high quality. I particularly recommend the Adobo seasoning!
