No, traditional Manner wafers are not gluten-free because their primary structural ingredient is wheat flour, which naturally contains gluten proteins essential for providing the elasticity, structure, and crisp texture of the baked wafer sheets. Individuals with celiac disease, non-celiac gluten sensitivity, or wheat allergies must avoid consuming classic Manner wafers. While some specialty food manufacturers produce alternative gluten-free wafer versions using rice or potato starch, the authentic historical Manner recipe relies strictly on wheat flour.
