A New Kind of Coffee Habit

On September 29, 2025, Starbucks will do more than celebrate National Coffee Day. The company is launching Protein Cold Foam and Protein Lattes across U.S. and Canadian stores.

It’s a bold move. Starbucks knows that customers want more than caffeine. They want drinks that satisfy hunger, fuel workouts, and fit into wellness routines. Protein has become the nutrient of choice, and coffee is now the carrier.

Protein Matters

Protein is no longer a gym-only obsession. It has gone mainstream. People value its ability to keep them full, repair muscles, and stabilize energy. Unlike carbs or fats, it has avoided controversy.

By weaving protein into drinks that customers already buy, Starbucks eliminates the need for a separate shake or snack. Coffee time becomes fueling time.

Cold Foam

Cold Foam has been one of Starbucks’ most successful innovations. Now it gets a functional twist. Each topping adds around 15 grams of protein to any iced drink.

The flavor list is wide: vanilla, sugar-free vanilla, chocolate, matcha, brown sugar, banana, salted caramel, pumpkin, and pecan. There’s also an unsweetened option. Customers can go decadent or minimal, seasonal or everyday.

Lattes

The Protein Latte takes things further. A grande comes packed with 27–36 grams of protein. That’s comparable to a protein shake.

These lattes use fortified 2% milk blended with unflavored protein powder. The result is creamy, familiar, and functional. Flavors include vanilla, caramel, chocolate, and brown sugar.

Commuters

Morning customers often skip breakfast. A Protein Latte solves that by offering caffeine and nutrients in one.

Fitness Fans

“Proffee” (protein coffee) has been a DIY hack online for years. Starbucks now makes it mainstream and consistent.

Seasonal Flavor Lovers

Pumpkin and apple crisp foams allow Starbucks to link wellness with comfort. Customers can indulge while still hitting their macro goals.

Taste and Texture First

The challenge with protein is chalkiness. Starbucks claims its foams are silky, its lattes smooth. If the mouthfeel holds up, the drinks will satisfy both wellness seekers and texture lovers.

Rolling this out nationwide from day one makes Starbucks the most accessible source for protein coffee.

The Wellness Narrative

This launch builds on Starbucks’ history of adapting to trends: alternative milks, sugar-free options, plant-based foods. Protein is the logical next step.

By offering it in mainstream formats, Starbucks signals that wellness is no longer niche. It’s built into the everyday coffee experience.

Questions of Sustainability

Critics note that dairy production carries a heavy climate cost. Starbucks has pledged to cut emissions by 50% by 2030. Future versions may include plant-based protein foams, satisfying both wellness and sustainability.

Seasonal and Future Innovations

Starbucks thrives on seasonal rotations. Expect:

• Peppermint Protein Foam in winter

• Strawberry or honey almond protein flavors in spring

• Coconut or mocha mint protein drinks in summer

Protein will likely become a permanent menu pillar, not just a one-off.

How to Try It

For a light lift: Iced Americano with unsweetened Protein Cold Foam (~15g protein).

For comfort: Caramel Protein Latte (~30g protein).

For festive flavor: Pumpkin Cold Foam Cold Brew (15g protein).

For recovery: Chocolate Protein Latte (~35g protein).

Impression

With Protein Cold Foam and Protein Lattes, Starbucks changes the story of coffee. No longer just about energy or comfort, coffee now delivers function.

For customers, it’s a convenient way to add protein to daily routines. For Starbucks, it’s a chance to dominate the “proffee” space before competitors react. For the industry, it signals a cultural shift—coffee as fuel, not just ritual.

On September 29, 2025, Starbucks isn’t just celebrating coffee. It’s redefining it.
