I am a celiac. Drank red wine, have rash. Can it be from sulfites?

Yes. Many people with or without celiac are sensitive to sulfites.
Histamine? Many patients with celiac with have bacterial overgrowth in the gut as well. Fermented foods, such as vinegar and wine may contribute to excess histamine production from the bacteria and the intake of the fermented food. It is also possible to be sensitive to sulfites but more likely it is related to histmine production in the gut.
