About the Iced Vanilla Protein Matcha Latte
The Starbucks Iced Vanilla Protein Matcha Latte starts at £6.75 and carries 160 calories in a Grande with 21.1g of protein. Matcha and cold milk go over ice with sugar free vanilla syrup, and a vanilla protein cold foam sits on top.
Iced is the better format for this drink than hot. Protein foam holds its structure while it stays cold, so the layer that thins within fifteen minutes on the hot version is still sitting there long after, and there is no risk of the acidity in green tea curdling the protein against heat. The foam also shows better on matcha than on coffee: white over jade rather than white over brown.
21.1g of protein for 160 calories is a better ratio than the hot version manages at 25.2g for 215, and the sugar is lower too at 9g against 14.3g. Fat is 2.9g with 1.6g saturated. Caffeine runs 59.2mg in a Tall, 70.7mg in a Grande and 87.6mg in a Venti, all from the matcha. Calories are 145 in a Tall and 168 in a Venti.
The size steps are unusually flat, and that is worth knowing before paying up. A Venti carries only 23 more calories than a Tall and 17mg more caffeine, because the extra volume is largely ice. The protein moves proportionally less than the price does. A Tall is the efficient order here and a Grande the sensible middle; the Venti buys mostly cup.
It is the most expensive cold drink on the Starbucks UK menu at £7.70 for a Tall. Drink it without stirring for the first third and the foam gives a thick vanilla opening before the tea arrives. The Iced Matcha Latte is the plain version at 117 calories, and the Iced Caramel Protein Latte is the coffee based protein drink with 24.2g.

How to Make a Iced Vanilla Protein Matcha Latte at Home
Everything cold from start to finish, which removes the one thing that can go wrong with protein and green tea.
Ingredients
Matcha base
Vanilla protein cold foam
Method
0 of 4 stepsTips
- Whey isolate rather than casein. Green tea is acidic enough to curdle a casein blend on contact.
- Let the matcha cool before it meets the protein foam. That is the only heat anywhere in this drink and it is the only risk.
- Sift the powder. Lumps are very visible against a pale drink.
Variations
- Unflavoured protein and a real vanilla pod steeped in the milk overnight.
- Oat milk, though the foam comes out looser than with dairy.
- Half the matcha for a milder drink at around 35mg of caffeine in a Grande.
Tall clear glass, unstirred. White over jade is the best looking layer on the cold menu and it holds twenty minutes.
