What happened
Class-action lawsuit filed against Starbucks over sugar-free protein drink labeling
A federal class-action lawsuit was filed in U.S. District Court for the Western District of Washington alleging that Starbucks misleadingly markets eight protein beverages as "Sugar-Free" despite containing naturally occurring sugar from milk. The lawsuit was filed by three individual consumers from California, New York, and Washington, represented by law firm Hagens Berman. The plaintiffs contend that the product names violate federal regulations governing sugar-free labeling claims and seek damages, restitution, and an order barring Starbucks from marketing beverages as "Sugar-Free" unless they meet applicable requirements.
Starbucks sugar-free protein drinks contain 13-21 grams of sugar per serving
According to the lawsuit complaint, Starbucks' eight sugar-free protein beverages contain between 13 and 21 grams of sugar per venti serving. Specific examples cited include a Sugar-Free Caramel Protein Matcha containing 21 grams of sugar and a Sugar-Free Vanilla Protein Matcha containing 20 grams. The sugar comes from lactose naturally present in the milk used to make the beverages. By comparison, a single Reese's peanut butter cup contains 11 grams of sugar.
FDA regulations require sugar-free claims to contain less than 0.5 grams of sugar
According to the lawsuit complaint, Food and Drug Administration regulations permit a "sugar free" claim only when a food or beverage contains less than 0.5 grams of sugar per reference amount customarily consumed and per labeled serving. The plaintiffs argue that Starbucks' protein drinks exceed this threshold due to lactose in the milk. Additionally, the plaintiffs contend that Starbucks fails to provide a required calorie disclaimer for products making a sugar-free claim that are not labeled as low or reduced calorie.
Starbucks launched protein beverage line in September 2025
Starbucks introduced its protein drink lineup in September 2025 to meet consumer demand for functional beverages and to compete with rivals like Dutch Bros, which had launched protein-enhanced coffee drinks in 2024. The beverage line includes hot and iced versions of Sugar-Free Vanilla and Caramel Protein Lattes and Protein Matchas.
Starbucks disputes mislabeling allegations and defends product labeling practices
Starbucks responded to the lawsuit allegations by stating the company believes the claims have no merit. The company argues it has consistently and clearly provided information about its protein beverages across product announcements, menus, marketing materials, its website, and mobile app. Starbucks distinguishes between total sugar and added sugar, noting that it does not add sugar to the drinks and uses sugar-free syrup for flavoring. The company stated it intends to vigorously defend itself in the matter.
