Q: Does it contain artificial sweeteners?

The Sugar-Free Vanilla syrup is sweetened with sucralose . If you prefer to avoid artificial sweeteners completely, you can simply order the drink "No Syrup" and enjoy the pure, natural, earthy flavor of the unsweetened matcha combined with the rich Protein-boosted Milk.

Question 1

What makes the milk "Protein-boosted"?

Accepted Answer

Starbucks baristas prepare the Protein-boosted Milk fresh every day by blending standard 2% dairy milk with premium, unflavored whey protein isolate. This process adds approximately 12–16 grams of protein per serving compared to a regular latte, creating a noticeably richer and more satisfying drink without altering the classic milk flavor.

Question 2

Is the matcha itself sugar-free?

Accepted Answer

Yes. In 2026, Starbucks switched to a 100% unsweetened matcha powder across all locations. In the standard Iced Protein Matcha, any sweetness comes entirely from added syrups. This version uses Sugar-Free Vanilla syrup instead, keeping the overall carb and sugar content very low.

Question 3

Can I get this with oat milk or almond milk?

Accepted Answer

The pre-mixed Protein-boosted Milk is made exclusively with 2% dairy milk. Plant-based milks (oat, almond, soy, etc.) do not come with the pre-blended protein boost. However, you can order the drink with your preferred non-dairy milk and request Protein Cold Foam on top to add a similar protein enhancement.

Question 4

How much caffeine is in this drink?

Accepted Answer

Matcha delivers a moderate, clean caffeine source. A Grande Iced Sugar-Free Vanilla Protein Matcha contains about 80 mg of caffeine — slightly less than a typical brewed coffee. Thanks to the natural L-theanine in matcha, the energy feels smoother, calmer, and more sustained compared to coffee.

Question 5

Is there any "chalky" texture?

Accepted Answer

No. The 2026whey protein isolate formula is highly soluble and specifically engineered to avoid any chalky or powdery aftertaste. When the drink is shaken with ice, it produces a smooth, velvety, and actually creamier texture than a standard matcha latte.

Question 6

Does it contain artificial sweeteners?

Accepted Answer

The Sugar-Free Vanilla syrup is sweetened with sucralose. If you prefer to avoid artificial sweeteners completely, you can simply order the drink "No Syrup" and enjoy the pure, natural, earthy flavor of the unsweetened matcha combined with the rich Protein-boosted Milk.
