Yes, the Blue Milk (and the Green Milk) served at Star Wars: Galaxy's Edge in both Disneyland and Hollywood Studios is gluten-free and plant-based. The drink is a frozen blend of coconut and rice milks, which makes it safe for guests with gluten sensitivities as well as those who are lactose intolerant or vegan. The fruity, tropical flavors are derived from natural and artificial sources that do not contain wheat or barley derivatives. However, Disney always includes a disclaimer that while the recipe is gluten-free, the items are prepared in a "shared kitchen environment" where cross-contact is possible. In 2026, guests with severe allergies are still encouraged to ask for the "Allergy Binder" at the Milk Stand or speak with a lead Cast Member to verify the current ingredient list, as suppliers and recipes can occasionally change. For most gluten-free travelers, the Blue Milk is a reliable and "Instagrammable" treat that is perfectly safe to enjoy.
