What does single-cultivar matcha mean?
Each tin holds matcha from just one cultivar, a single variety of the tea plant. Nothing is blended, so every cultivar keeps its own taste. Most matcha on the market is a blend of several cultivars, combined for a balanced, consistent flavour.
What is the difference between ceremonial grade and high-grade matcha?
The term "ceremonial grade" has become a marketing label. We prefer to call matcha what it actually is: high-grade matcha. Not because it sounds premium, but because it reflects the quality in the cup: brighter green colour, smoother texture, natural sweetness and a cleaner, more balanced taste.
What's the difference between matcha and green tea?
With regular green tea, you steep the leaves in hot water and then remove them, so you drink an infusion. Matcha is the whole shade-grown leaf, stone-milled into a fine powder and whisked into water, so you drink the leaf itself.
Which matcha should I choose for lattes or for drinking straight?
- Lattes and everyday: Daily Matcha Okumidori works for everything from straight matcha and lattes to smoothies and baking. Okumidori is one of the most vivid cultivars, and its colour holds in milk.
- Straight, to start with: Yabukita, the most common cultivar in Japan: consistent, reliable and clean in the cup. It works with milk too.
- Straight, smooth and floral: Saemidori: exceptionally smooth, floral and sweet.
- Straight or as thick tea (koicha): Gokou (dark chocolate, sweet cream, long finish) and Asahi (the cultivar of choice for formal tea ceremony).
- Two cultivars to compare: the MATCHA DUO Umami Bomb (Gokou + Okumidori).
- Not matcha: Hojicha, roasted green tea for lattes, desserts and baking.
All cultivars side by side: Compare our matchas.
How do I prepare matcha (usucha)?
One cup, as on every Green Room Matcha tin:
- Sift 3 g of matcha through a fine sieve.
- Add 60 ml of water at 75–80 °C.
- Whisk for 15–20 seconds.
How do I make a matcha latte?
Prepare one cup of matcha as above, then combine it with 150 ml of milk of your choice.
Can I make iced matcha?
Yes. Whisk your matcha with water as usual, pour it over ice and top it up with cold water or cold milk.
Why should I sift matcha?
Sifting removes clumps, so the matcha whisks up smooth.
Why shouldn't I use boiling water for matcha?
Boiling water is too hot for matcha and can make it taste bitter. Heat fresh water and let it cool to 75–80 °C.
Why is my matcha bitter or clumpy?
- Bitter: the water is too hot, or there's too much powder for the amount of water. Stick to the values on the tin (see "How do I prepare matcha (usucha)?").
- Clumpy: the matcha wasn't sifted, or it wasn't whisked long enough.
What do I need to prepare matcha?
A fine sieve, a bowl and a whisk. Traditionally that's a matcha bowl (chawan) and a bamboo whisk (chasen); a handheld milk frother works too. A small kitchen scale helps with measuring.
How do I prepare hojicha and a hojicha latte?
- Take 3–4 g of hojicha.
- Add 60 ml of water at 90 °C.
- Whisk for 15–20 seconds.
For a hojicha latte, combine it with 150 ml of milk of your choice. Flavour profile: toasted caramel, roasted nuts, soft umami, cocoa finish.
How should I store matcha?
Airtight, cool and dry, away from light and strong smells. Reseal the tin tightly after every use, and keep opened matcha in the fridge. Hojicha: keep it in a cool, dry place away from light, as it says on the tin.

How much caffeine is in matcha?
About 100 mg per 3 g serving, typically 60–130 mg depending on the matcha. That's roughly as much as an espresso or a cup of filter coffee, and about twice as much as a cup of black tea.
This figure comes from Japan's official food composition tables (MEXT), not from a lab test of our matcha.
Does hojicha have less caffeine than matcha?
Yes. Hojicha is roasted green tea and usually contains noticeably less caffeine than matcha. We don't have a measured figure for our hojicha.
How much matcha per day is OK?
According to the European Food Safety Authority (EFSA), up to 400 mg of caffeine a day from all sources, and up to 200 mg at once, raise no safety concerns for healthy adults. That's about 4 servings of matcha a day, or 2 at once. For pregnancy and breastfeeding, EFSA's figure is 200 mg a day. If you're sensitive to caffeine, pregnant or unsure, check with your doctor.
What's in matcha?
Shade-growing raises the chlorophyll and amino acids in the leaf, which gives matcha its deep green colour and umami taste.
Matcha naturally contains caffeine, the amino acid L-theanine and tea catechins. Vitamin K is also notable: about 87 µg per 3 g serving (MEXT). If you take blood thinners, talk to your doctor.
Is matcha healthy?
We don't make health claims. In the EU, food may only be advertised with officially approved health claims, and none is approved for matcha or green tea. What's in matcha and how much caffeine it has is covered above.
