The Full Answer
Coffee beans are naturally gluten-free. Plain brewed coffee, espresso, cold brew, and black coffee contain zero gluten regardless of the brand or roast level.
However, some coffee products and preparations can introduce gluten risks. Flavored coffee beans may use malt-based or wheat-derived flavorings. Specialty coffee drinks at cafes may use syrups, sauces, or toppings that contain gluten. Instant coffee and coffee mixes occasionally contain wheat-based fillers.
Barley-based coffee substitutes (like Pero or Postum) are NOT gluten-free. Starbucks and most major chains have GF options — plain coffee, espresso, and most flavored syrups are safe, but always verify.

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.
- 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.
