Starbucks' own menu lists up to 21 grams of sugar in a protein drink it calls sugar-free
Starbucks faces a federal lawsuit over eight 'sugar-free' protein drinks, one of which its own US menu lists at 16 to 21 grams of sugar. The same page says no sugar is added, so the case tests whether a printed gram count can answer a name that promises none.

What happened
- Class-action firm Hagens Berman filed the suit on behalf of three consumers who bought the drinks in California, New York and Washington.
- The plaintiffs call Starbucks' naming and marketing of the drinks "false, deceptive and unlawful" and say it violated federal labeling regulations.
- Starbucks says the sugar comes from the protein-boosted milk it uses, and that it adds no sugar and flavors the drinks with sugar-free syrup.
- The suit seeks damages for US buyers and a court order barring Starbucks from calling products that contain sugar "sugar-free".
- Starbucks launched the protein line in September 2025 to catch up with Dutch Bros, which began selling protein coffee drinks in 2024.
Compiled by The Board RoomSomething wrong?How this is made
Why it matters
- exposure Starbucks printed both the gram counts and the no-added-sugar note and was sued anyway, so a complete nutrition panel beside a contradicting product name leaves any operator open to the same complaint.
- decision Chains naming milk- or protein-based drinks now choose between finished-cup claims like 'sugar-free' and recipe claims like 'Zero Sugar Added', and this suit attaches litigation risk to the first.
- precedent An order against Starbucks would bind only Starbucks, but it would set a reading of 'sugar-free' for drinks whose sugar comes from the base ingredient that later suits could cite.
Starbucks' own website shows the plaintiffs' central point. On Monday the company's US menu listed the 20-ounce Sugar-Free Caramel Protein Matcha at 21 grams of sugar and the 16-ounce size at 16 grams [2]. A Reese's peanut butter cup has 11 grams [3]. The larger drink holds 10 grams more than the candy, close to two cups' worth [14].
Starbucks' answer is on the same site. According to ABC News, the page marketed the drinks as "sugar-free" and also stated the sugar in each beverage and that they were made without added sugar [8]. "We believe these claims have no merit," a Starbucks spokesperson said. The spokesperson said the company "has consistently and clearly provided information about its protein beverages, sugar-free options, customization choices and nutritional content" across its menus, website and app, and added, "we intend to vigorously defend ourselves in this matter" [9].
Steve Berman, a co-founder and managing partner of Hagens Berman, made the case for the buyers. "Consumers avoid sugar for various reasons, whether that be general health, diabetes and blood glucose levels or other factors, and for many, a staunch mislabeling like this is significant," he said [5]. The ABC report does not say which federal labeling rule the complaint relies on, or what sugar level that rule allows under a "sugar-free" name.
A skeptic of the suit would make Starbucks' argument: a buyer who read the page had the gram count. A rival's menu shows another way to name a similar drink. Dutch Bros sells its lower-sugar caramel protein latte as the Hopscotch Zero Sugar Added Protein Latte, a name that describes the recipe [11]. Starbucks' name makes a claim about the finished cup. The 16-ounce iced Dutch Bros drink has 7 grams of sugar and 11 grams of protein [11]. Starbucks' iced Sugar-Free Caramel Protein Latte at the same 16-ounce size carries 29 grams of protein and 9 grams of sugar [12]. That is 2 grams more sugar and about 2.6 times the protein [15]. Per gram of protein, the Dutch Bros drink carries roughly twice the sugar [16].
The two drinks are close on composition, so Starbucks' exposure sits in the wording. That is also where its decision for this quarter sits. If Starbucks renames the line while the suit is pending, the plaintiffs get the order they asked for before a judge has ruled on it [13]. If it keeps the name, every further sale goes to the kind of buyer the suit says it represents. The spokesperson's statement points to the second course [9]. We do not know yet whether a court will treat a printed gram count as an answer to a product name. The complaint was filed late Friday [1].
What to watch
- Whether Starbucks changes the drink names or menu wording while the Seattle case is pending.
- Starbucks' first formal response in court, and whether a judge treats the printed gram counts as an answer to the 'sugar-free' name.
- Whether the court lets the three buyers sue on behalf of all US purchasers of the eight drinks.
