Hey auggy! My son is celiac, too. I don't give him any of the flavored teas, as they use the same machine to mix all the teas and, even though they clean it between batches, they can't guarantee there's no cross contamination. For instance, are the new chocolate chips in the chocolate chip tea gluten free? Who knows .... So, I stick to giving him only the plain teas: english breakfast, dragonwell, silver needle, etc. You get the drift. I'm no expert, for sure, but that's my take on it after some correspondence with Adagio. Good luck!
