The short version
Company: Starbucks
Product: Sugar-Free Protein Lattes and Protein Matchas, hot and iced

Where it was filed: U.S. District Court, Western District of Washington
Status: Proposed class action, nothing proven
What the lawsuit claims
According to Fox Business, the lawsuit says Starbucks markets eight protein beverages as "Sugar-Free" even though they contain naturally occurring sugar from milk. ClassAction.org, which reviewed the 46-page complaint, lists the drinks as the Sugar-Free Vanilla and Caramel Protein Lattes and the Sugar-Free Vanilla and Caramel Protein Matchas, in hot and iced versions. The complaint says they launched in September 2025. It says milk is the first or second ingredient in each drink.
The complaint says the drinks contain 13 to 21 grams of sugar per venti serving, Fox Business reported. It says federal law allows "sugar free" only at 0.5 grams of sugar or less per serving. It says 21 grams in a venti Sugar-Free Caramel Protein Matcha is roughly five teaspoons, "almost as much total sugar as is contained in a standard Kit Kat bar." The suit also alleges Starbucks left off required calorie disclaimers. It says each drink has about 270 to 340 calories per venti, according to ClassAction.org.
Starbucks' side
A Starbucks spokesperson told Fox Business: "We believe these claims have no merit." The statement says Starbucks has consistently and clearly provided information about its protein beverages, sugar-free options, customization choices and nutritional content, and that it intends to defend itself vigorously. Fox Business reports that Starbucks disputes the allegations. The dispute is framed as total sugar versus added sugar. None of the claims in the lawsuit has been proven in court.
