What’s happening

Starbucks is launching Starbucks Coffee & Protein — a bottled ready-to-drink lineup hitting grocery and convenience stores March 23, 2026.

What’s in the bottle

Each 12oz bottle is positioned as a “macro coffee” option with:

  • 22g complete protein

  • 5g prebiotic fiber

  • Five vitamins and minerals

  • 2g sugar

  • Two flavors: Classic Caffè and Caffè Mocha

Why this matters

This is Starbucks trying to own a daily habit beyond café visits. RTD protein coffee is the perfect cross-category bridge: it’s coffee, it’s function, and it makes your morning routine feel “productive.”

What to watch next

  • Retail placement (front cooler wins)

  • Whether it expands into more flavors or formats

  • How it competes vs. existing RTD protein coffees already fighting for space
