The Full Answer
The US ingredient list for Coca-Cola Original is carbonated water, high fructose corn syrup, caramel color, phosphoric acid, natural flavors and caffeine — none of them wheat, barley or rye. Coca-Cola's allergen FAQ says that if a product contains any of the major allergens (wheat is one), it is named in the ingredient list on the label. The Celiac Disease Foundation lists sodas among beverages that are gluten-free.
One honest caveat: Coca-Cola's own gluten FAQ only calls its 100% juice products gluten free; for other drinks it asks people to contact the company. So "gluten-free" here is based on the ingredients and the allergen policy, not a gluten-free claim on the can.
Coca-Cola's page lists Caffeine Free Coke with the same ingredients minus caffeine, and Mexican Coke made with cane sugar. The rare gluten concern with sodas is barley malt in some craft or specialty drinks — not in Coca-Cola.

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.
- 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.
