Starbucks is facing a federal lawsuit over its 'sugar-free' protein drinks, which allegedly contain more sugar than a Reese's peanut butter cup. The suit, filed in Seattle on Friday by law firm Hagens Berman, claims that eight of the chain's protein beverages contain between 13 and 21 grams of sugar per serving despite being labeled as sugar-free.

The lawsuit names four warm and four iced protein drinks, including Sugar-Free Caramel Protein Matcha, which is listed as containing 16 grams of sugar in a grande (16-ounce) serving and 21 grams in a venti (20-ounce) serving. For comparison, a single Reese's peanut butter cup contains 11 grams of sugar.

Starbucks has responded by stating that the sugar in its protein drinks comes from the protein-boosted milk used, not added sugars. A spokesman emphasized that the company clearly provides nutritional information across various platforms and intends to vigorously defend itself against these claims.

The plaintiffs allege that Starbucks' labeling is 'false, deceptive, and unlawful,' violating federal regulations which stipulate that a product can only be labeled as 'sugar-free' if it contains no more than 0.5 grams of sugar per reference amount. The lawsuit seeks unspecified damages for U.S. consumers who purchased these drinks and aims to prevent Starbucks from using the 'sugar-free' label on products containing sugar.
