Starbucks has declared itself all in on protein. Beginning this month, customers can order Protein Lattes and Protein Matchas, or add Protein Cold Foam to their cold brews and Frappuccinos, turning a daily caffeine ritual into something resembling a workout supplement. This isn't simply about menu items. It signals how deeply the protein craze has embedded itself into American culture. Across the grocery aisle, protein has become the nutrient of the moment, highlighted with the same zeal once reserved for fat-free labels.
it has also debuted protein-enriched milk and cold foams for specialty drinks like the Iced Banana Cream Protein Matcha (24 grams of protein) and the Chocolate Cream Protein Cold Brew (19 grams). The banana number was mostly inoffensive (and flavorless) but the juiced-up matcha smacked of a musky, powdery flavor that was unpleasant. The chocolate cold foamed coffee had an actual cocoa flavor that worked well with the robust cold brew, and the double whammy protein-spiked vanilla latte and cold foam was sweet, but tasty.
