The Full Answer

The risks are in the add-ons: some flavored powders, syrups, and non-dairy "creamers" can contain wheat or malt, certain toppings (like some pudding or cookie-crumb toppings) contain gluten, and busy shops may have cross-contamination. Pearls are usually GF but a few specialty varieties are not.
To order safely, choose a plain tea base with classic tapioca pearls, skip cookie/pudding toppings and powders you can't verify, and ask the shop which ingredients are gluten-free.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces — such as shared cutting boards, toasters, fryers, or utensils — rendering otherwise safe food dangerous for people with celiac disease.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
