Not all matcha is created equal. Here's how to tell the good stuff from the green dust.
Matcha is whole green tea leaves, shade-grown and stone-ground into powder. With steeped tea you drink what comes out of the leaf. With matcha you drink the leaf itself.
That's why quality matters more with matcha than with almost any other tea. Whatever is in the powder, good or stale, ends up in you.
First, a Word on Grades
You'll see "ceremonial", "premium", "culinary" and "latte grade" on packs. None of these are regulated. A brand can put any of them on anything.
So don't buy the label. Buy what the label is supposed to mean: young, shade-grown leaves, carefully processed and fresh. Here's how to check.
What Makes Good Matcha
| Factor | Good matcha | Budget matcha |
|---|---|---|
| Shading | Shaded for several weeks before harvest, which raises chlorophyll and L-theanine | Little or no shading: duller colour, more bitterness |
| Leaf | Young, tender first-harvest leaves, stems and veins removed | Older, later-harvest leaves, sometimes with stems |
| Grinding | Slow stone milling for an ultra-fine, silky powder | Fast machine grinding: coarser, and heat can dull the flavour |
| Origin | Named region and producer (e.g. Uji, Nishio, Kagoshima, Shizuoka) | Vague ("product of Asia") or not stated |
Where it comes from: Uji, near Kyoto, is matcha's historic home. Nishio, Kagoshima and Shizuoka are also known for it. A named region isn't a guarantee, but a producer who tells you where and when it was grown has nothing to hide.
The Five-Second Check
- Colour: vivid, bright green. Olive, yellowish or brownish means older leaves or old powder.
- Texture: fine as talc. Rub a pinch between your fingers; it shouldn't feel gritty.
- Aroma: fresh, grassy and a little sweet. Flat or hay-like means it's stale.
- Taste: smooth with natural sweetness and umami. Some bitterness is normal; harsh and astringent isn't.
- Freshness: check the harvest or packing date. Matcha oxidises fast once opened.
Price is a clue, not proof. Good matcha takes weeks of shading, hand care and slow milling, so it's never cheap. But a high price doesn't guarantee any of that. Look for the detail behind the price.
What Matcha Actually Gives You
Because you drink the whole leaf, matcha delivers more of green tea's compounds per serve than a steeped cup. Here's what that means, honestly.
- Calm energy and a cognitive edge: about 30–70 mg caffeine per serve (1–2 g of powder), plus L-theanine. In trials, that pairing sharpened focus more than caffeine alone. It feels smoother than coffee mainly because there's less caffeine.
- A steady nudge to your metabolism: green tea's catechins and caffeine shift your body a little toward burning fat for fuel. A modest effect, best when it's daily and alongside movement, not a fat burner.
- Calmer inflammation, starting in the gut: most EGCG stays in your gut, which is where the strongest human evidence is.
Matcha also contains small amounts of vitamins and minerals, but at 1–2 g a serve it isn't a meaningful source of them. Drink it for the tea.
Did You Know?
Powdered tea came to Japan with Zen Buddhist monks in the 12th century, who drank it to stay alert and calm through long hours of meditation. Calm focus has been matcha's job for about 800 years.
How to Enjoy It
Straight up: sift 1–2 g (about ½–1 teaspoon) into a bowl, add 60–80 ml water at about 75–80°C, and whisk in a quick zig-zag until frothy. Top up with more water if you like it lighter.
As a latte: whisk the matcha with a splash of water first, then add warm milk. What you add changes the drink more than the matcha does:
| Per ~200 ml serve (approx.) | Calories | Worth knowing |
|---|---|---|
| Matcha with water | ~5 | Nothing added. The purest way to taste quality. |
| With skim milk | ~70 | About 7 g protein; about 10 g natural milk sugar (lactose). |
| With unsweetened oat milk | ~80–100 | Low protein. Many "unsweetened" oat milks still have a few grams of sugar from processing. Check the label. |
| With a splash of coconut cream (our favourite) | ~50–100 | Rich and creamy with almost no sugar; mostly saturated fat, so keep it to a splash. |
Watch the café version: many matcha lattes come with syrups and 15 g+ of sugar. That's dessert, not tea.
Quick FAQs
How much caffeine is in matcha? About 30–70 mg per serve, depending on how much powder you use. A filter coffee is around 95 mg.
Is matcha OK every day? Yes. One to two serves a day keeps caffeine moderate. The safety concerns in the research relate to high-dose green tea extract capsules, not to drinking tea.
How should I store it? Airtight, dark and cool. Once opened, keep it in the fridge and use it within 1–2 months.
Does colour really tell you quality? Mostly, yes. A vivid green points to shaded, young leaves and fresh powder. Dull or yellow powder is usually older leaf or old stock.
