First time trying Dutch Bros and was super impressed! They have an extensive allergy menu that shows any items with wheat. The only other four sources of gluten are from four flavors of the Torani syrups they use (caramel, sugar free caramel, toasted marshmallow and sugar free s’mores) so as long as you avoid those + any toppings with wheat, you should be good. Their oat milk is not gluten free but they have almond milk, coconut milk and regular. The steam wand, scoop, mix tins and blenders are also rinsed with hot water after every drink.
