Starbucks Faces Federal Suit Over 'Sugar-Free' Protein Drinks Containing Up to 21 Grams of Sugar
A federal lawsuit filed in Seattle alleges that eight Starbucks protein beverages marketed as 'sugar-free' contain significant amounts of sugar, with some versions holding more than a Reese's peanut butter cup. The suit, brought by Hagens Berman on behalf of three consumers, claims the labeling is deceptive and violates federal regulations. Starbucks defends its position by stating the sugar comes from protein-boosted milk, not added sweeteners, and asserts it clearly disclosed nutritional facts. The company, which launched these drinks in September 2025 to compete with rivals like Dutch Bros, intends to vigorously defend against the claims of false advertising.
