Is 100% Concord Grape Juice Gluten Free?

The Ingredient Breakdown

When evaluating any beverage for gluten safety, we look strictly at the source ingredients and any additives used for preservation or processing. For 100% Concord Grape Juice, the ingredient list is remarkably simple and naturally free of gluten.

The primary ingredient is, of course, Grape Juice. Whether derived from fresh grapes or from concentrate (which involves adding water back to Grape Juice Concentrate), the source is fruit. Unlike barley, rye, or wheat, grapes do not contain gluten proteins. The processing of grapes into juice does not introduce gluten unless cross-contamination occurs, which is rare in dedicated fruit facilities.

A common additive you will see is Potassium Metabisulfite. This is a preservative used to maintain color and prevent oxidation (browning) in the juice. It is a sulfur-based compound and is entirely gluten-free. It is also important to note that this ingredient is generally safe for those with celiac disease, though individuals with severe sulfite sensitivities should be aware of its presence.

Nutritional Value

While 100% Concord Grape Juice is gluten-free, it is important to view it through a nutritional lens. This juice is rich in antioxidants, specifically polyphenols like resveratrol, which are found in the skin of the grapes. These compounds are linked to heart health and reduced inflammation.

However, because it is 100% juice, it is a concentrated source of sugar. A standard serving contains a significant amount of natural sugar and calories, similar to soda, but without the added high-fructose corn syrup. It fits into a healthy diet in moderation, but for those strictly monitoring blood sugar or caloric intake for weight loss, portion control is essential.
