The Full Answer
Black, green, white and oolong tea are leaves of the tea plant and contain no gluten. Bigelow says tea is a naturally gluten-free beverage and that all current Bigelow teas use no grains or gluten-containing ingredients.
The exceptions are herbal and "coffee-style" blends that add grain. Celestial Seasonings says some of its teas contain roasted barley, an ingredient that contains a form of gluten — its Roastaroma lists roasted barley first. Celestial uses third-party certification from the Gluten Free Certification Organization (GFCO) on every box it labels gluten free, so look for that seal.
Bubble tea and chai lattes are different drinks with their own risks; see those pages.

Celiac Safety Glossary
- 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.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
- 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.
