Starbucks is taking the ready-to-drink (RTD) coffee scene to the next level. From protein-packed beverages to zero sugar indulgences and light iced espresso, there's now a Starbucks drink for every lifestyle. All beverages launched nationwide on March 23, 2026, available in grocery stores, convenience stores and online.
With RTD drinks, Starbucks brings coffeehouse-quality flavors, functional ingredients and convenient on-the-go options straight to your fridge.
1. Protein Drinks: Fuel Your Day with Coffee & Nutrition
For those looking to combine morning coffee with a nutritional boost, Starbucks introduces Coffee & Protein RTD beverages. Each 12 fl. oz. bottle provides:
- 22 grams of complete protein – supports muscle repair and satiety
- 5 grams of prebiotic fiber – aids digestive health
- Five essential vitamins and minerals – supports daily nutrition goals
- Only 2 grams of sugar – minimal impact on blood sugar levels
Available Flavors
- Classic Caffè: Bold coffee taste blended with protein for a smooth, satisfying boost that keeps you energized through the morning.
- Caffè Mocha: A decadent blend of rich cocoa and Starbucks coffee with protein, perfect for chocolate lovers who want flavor without excess sugar.
Price: $3.99 per 12 fl. oz. bottle
Why It Stands Out
These drinks make it easy to level up your morning routine without adding extra steps. Starbucks developed this line through the North American Coffee Partnership (NACP), combining premium coffee with functional ingredients that modern consumers seek.
Starbucks previously tested protein-forward beverages in their coffeehouses with Protein Lattes and Protein Cold Foams, and now RTD options bring the same innovation to grocery shelves.
2. Zero Sugar: Indulgent Flavors Without Added Sugar
For health-conscious coffee lovers or those tracking calories, Starbucks has zero sugar RTD beverages that do not compromise on taste.
Starbucks Doubleshot Energy Zero Sugar
- Flavors: French Vanilla & Dark Chocolate
- Calories: Under 100 per 15 fl. oz. can
- Benefit: Same bold coffee flavor and energizing effect as the original Doubleshot®, but with zero added sugar for guilt-free energy.
- Price: $3.59
3. Starbucks Frappuccino Lite: Chocolate Hazelnut Gelato
Indulge in the creamy, chocolatey goodness of Starbucks Frappuccino® Lite – Chocolate Hazelnut Gelato. This drink delivers the flavor of a classic Frappuccino® while keeping calories and sugar low, ideal for a lighter treat.
- Calories: 100 per 9.5 fl. oz. bottle
- Other flavors in the Lite line-up: Sea Salt Caramel, Creamy Vanilla, Double Chocolate
- Highlights: Velvety chocolate combined with rich hazelnut, smooth and creamy texture, no added sugar
- Price: $2.99
Why Zero Sugar Options Matter
Zero sugar drinks are a strong fit for anyone wanting Starbucks indulgence while keeping wellness goals on track, from lower sugar intake to calorie management.
4. Iced Espresso: Lighter Morning Indulgence
For fans of iced espresso seeking a low-calorie, low-sugar option, Starbucks offers Iced Espresso Lite Chilled Multiserve:
- Flavors: Vanilla Latte, Caramel Macchiato
- Calories: 90 per serving
- Sugar: Zero added sugar
- Size & price: 40 fl. oz., $7.49
- Benefit: Perfect for multiple servings or sharing, Starbucks' signature rich coffee taste without compromising wellness priorities.
Why It Stands Out
The Lite Iced Espresso line offers a lighter coffee experience for mornings or afternoon boosts, meeting demand for indulgent but lower-calorie bottled options.
Why Starbucks RTD Drinks Are a Game Changer
Starbucks RTD beverages line up with trends many shoppers care about:
- Protein for functional energy – busy mornings or workouts
- Fiber & vitamins for overall wellness – digestive health and daily nutrition
- Zero sugar options – flavor without excess calories
- Convenience – premium coffee and functional nutrition whenever you need it
With these options, Starbucks is expanding the coffeehouse experience into grocery aisles, more choice and control over morning routines, wellness goals and flavor preferences.
Suggested Serving Ideas
- Coffee & Protein: Drink chilled as post-workout recovery or on the way to work.
- Doubleshot Energy Zero Sugar: Mid-morning or mid-afternoon for a sugar-free energy boost.
- Frappuccino Lite: With breakfast or as an afternoon treat.
- Iced Espresso Lite: Over ice with a splash of milk, or straight from the bottle.
The Bigger Picture
This launch says a lot about where Starbucks is heading. It's not just about coffee anymore, it's about functional drinks (energy, hydration), lower-calorie alternatives and grab-and-go convenience. And this is likely just the beginning.

Coffee & Protein at 22 g protein + 2 g sugar is the highest protein-per-calorie ratio in Starbucks' entire RTD line. Comparable to a protein shake but with real coffee flavor.
Who Each Drink Is Best For
- Post-workout / meal replacement: Coffee & Protein (22 g protein is meaningful)
- Afternoon energy without sugar: Doubleshot Energy Zero Sugar
- Dessert-style low-cal treat: Frappuccino Lite

How RTD Stacks Up vs In-Store
A Grande Starbucks Protein Cold Brew (where available) delivers ~25 g protein for about $5.25. The RTD Coffee & Protein gives you 22 g for $3.99 and can be bought in advance, better economics if you're a regular protein-coffee drinker.
