Overview
- Available starting Sept. 29, the new beverages offer up to 36 grams of protein per grande and will stay on menus year-round.
- Protein Cold Foam adds about 15 grams of protein for roughly $2, while Protein-boosted milk—2% milk blended with whey—adds 12–16 grams for about $1.
- Featured items include Iced Banana Cream Protein Matcha, Iced Vanilla Cream Protein Latte, Chocolate Cream Protein Cold Brew, and four Protein Lattes, with rotating seasonal foam flavors like pumpkin and pecan.
- Starbucks confirms the protein source is whey, meaning the drinks contain dairy and are not vegan or suitable for many dairy-free customers.
- Early social media feedback is mixed, with some customers and baristas citing chalky or off flavors, as the company ties the launch to its turnaround efforts and plans a ready-to-drink protein milk for retail in 2026.
