Starbucks lists allergens only for its own food items; beverages and most third-party packaged snacks have no allergen list in its menu data, so only part of the menu has allergen information. Because cafés share equipment to store, prepare and serve unpackaged products, Starbucks says it cannot guarantee any of them are allergen-free; for beverages it refers customers to the ingredient statement or the package label.
