Starbucks uses Oatly Barista Edition oat milk as its oat milk of choice. This oat milk is specifically formulated for use in coffee beverages and has a creamy texture that froths well, making it ideal for lattes and cappuccinos. It is unsweetened and has a neutral flavor that does not overpower the taste of other ingredients. Starbucks began offering oat milk in its stores in the United States in 2021, and it is now available year-round as part of the core menu.
