Yes—the current Starbucks matcha powder is unsweetened, and one barista scoop adds about 3–10 calories depending on scoop size.

Hearty Sip
Here’s the short version that guides your order: the powder used today is pure ground green tea with no added sugar. That means calories from the powder itself stay tiny. The drink’s total reflects your milk pick and whether any syrup gets stirred in.
Calories In Starbucks Matcha Powder Today
Starbucks menus and regional nutrition booklets list unsweetened matcha powder as the base. You’ll see that phrasing on current product pages and in official region PDFs. When the powder is just green tea, a gram contributes roughly 3–4 calories. Barista scoops vary by store and drink size, but the common 1–2 gram scoop range lands you at about 3–10 calories from the powder itself. Regional nutrition sheets also publish caffeine figures for matcha lattes (around 80–85 mg per grande iced), which lines up with a small amount of tea powder rather than a sugary premix.
Why Your Cup’s Total Can Vary
Milk choice changes the picture the most. Dairy has natural lactose and fat; non-dairy options bring their own mix. Syrups shift totals further. The powder isn’t where the calories are—milk and flavor add-ons are.
Quick Math: Powder-Only Calories
The table below shows a practical range using typical scoop sizes. It uses widely referenced matcha nutrition (about 377 kcal per 100 g of pure powder), which translates to roughly 3.8 kcal per gram.
| Scoop Size (g) | Calories From Powder | Notes |
|---|---|---|
| 1 g | ~4 kcal | Typical “light” scoop |
| 1.5 g | ~6 kcal | Common for grande builds |
| 2 g | ~8 kcal | Heavier scoop or extra matcha |
Dial in your drink around your daily calorie needs and you’ll know where a latte can fit on active days and rest days.
What Starbucks Publishes Right Now
Recent Starbucks pages and region booklets describe the matcha base as “unsweetened matcha.” That phrasing is important because earlier third-party write-ups often quoted a sweetened blend. Current builds can still be sweet—just from syrup, not from the powder itself. Regional PDFs also show caffeine figures for iced and hot versions by size, with grande iced often sitting near ~85 mg.
Examples From Official Materials
Regional nutrition PDFs list “unsweetened matcha powder [Powdered Green Tea]” in the ingredient line for hot and iced matcha lattes and publish calories that mostly come from milk. Grande iced with semi-skim milk appears near ~117 kcal, while the same drink with whole milk rises higher. These are strong clues that the powder is not carrying the load; milk and syrup do. Starbucks’ US pages also present a Protein Matcha line with clear nutrition per grande, which shows how a different milk base shifts totals.
How Scoop Count Affects A Latte
More scoops mean slightly more calories from tea and a mild bump in caffeine. The change is small compared with swapping milk or tweaking syrup pumps. If you like a stronger tea flavor with minimal calorie change, ask for an extra scoop but hold syrup.
Your Order, Your Levers
- Milk: Skim/low-fat and most plant milks keep calories lower than whole-milk builds.
- Syrup: Fewer pumps = fewer calories. You can also ask for a half pump.
- Size: Tall beats grande when you want a lighter total without changing flavor.
- Scoops: Adjust for taste; the calorie impact stays small compared with milk or syrup.
Calorie Snapshots By Size
These ranges show what you can expect from official, recent materials. The iced values below reflect semi-skim style dairy; plant milks and added syrup nudge numbers up. Protein versions use a different milk base and come out higher.
| Size | Iced Matcha Latte* | Protein Matcha (Hot) |
|---|---|---|
| Tall | ~82–108 kcal | — |
| Grande | ~117–154 kcal | ~300 kcal |
| Venti | ~135–177 kcal | — |
*Iced latte figures and caffeine are published in a current regional Starbucks beverage nutrition booklet that lists “unsweetened matcha powder” in the ingredients. US protein listings show per-grande nutrition for the Protein Matcha line.
Health Angle: Powder Calories Are Tiny, But That Doesn’t Mean “Free”
Pure matcha brings antioxidants and a gentle lift, yet the drink still lives inside your daily energy budget. If you skip syrup and keep to a smaller size, powder calories hardly move the needle. If you like sweetness, trimming a pump or two is the fastest way to drop totals without losing the green tea flavor.
Reliable References You Can Check
Starbucks’ regional PDF spells out ingredients and nutrition for matcha lattes, including caffeine per size and the use of unsweetened powder. The US Protein Matcha page prints a clear per-grande panel. For a powder-only view, nutrition databases for plain matcha show the same low-single-digit calorie math per gram. You can cross-check what you order with those figures any time.
Ordering Tips To Hit Your Number
Keep It Light Without Losing Flavor
- Ask for no classic syrup or fewer pumps.
- Pick a milk that suits your target. Skim and many plant milks run lighter than whole milk.
- Choose tall for a smaller, tidy total on days you’re already near your target.
When You Want More Protein
The Protein Matcha line bumps protein and calories because the milk base changes. That’s handy on training days. It’s also why two matcha drinks can feel different even when the powder stays the same.
FAQ-Free Clarifications (Straight Answers)
Does The Powder Add Sugar?
No. Current materials show an unsweetened tea powder. Sweetness comes from syrup or a sweet milk base.
Why Do Some Websites Quote 25 Calories Per Scoop?
Many posts reference an older, sweetened blend. Today’s powder is unsweetened, so the scoop math uses pure matcha numbers. That’s why your drink’s calories mostly track milk and syrup—not the green tea powder.
Bottom Line For Your Order
If you want the green tea taste with the least calories, go milk-only with the unsweetened powder and skip syrup. If you enjoy sweeter, ask for fewer pumps. If you need more protein, the Protein Matcha option delivers, with a higher energy total.
