Matcha 101: How to Prepare Matcha at Home – Hot & Iced
Matcha has made the leap from Japanese tea ceremony to everyday ritual – and with it comes the question: do you need special equipment and years of practice to make a good one at home?
No. With a fine sieve, water at 70–80 °C and thirty seconds of whisking, you can make a smooth, naturally sweet matcha in any kitchen. The two classic problems – lumps and bitterness – are both easy to avoid once you know what causes them.
Here is the complete guide: hot, iced, and to go.

What Is Matcha, Exactly?
Matcha is green tea, ground into a very fine powder. The tea plants are shaded for a few weeks before harvest, which makes the leaves darker green and naturally sweeter; the leaves are then steamed, dried and traditionally stone-ground.
The crucial difference from regular green tea: you don't steep the leaves and throw them away – you whisk the whole leaf into water and drink it. That is why matcha tastes more intense, looks that vivid green and carries more of the leaf's caffeine into your cup than a brewed tea.
What You Need
You do not need a tea ceremony set. Three things do the job:
- A fine sieve. Non-negotiable – sifting is the single step that prevents lumps.
- Something to whisk with. The traditional bamboo whisk (chasen) is lovely to use, but an electric milk frother works just as well – arguably better for beginners.
- A small bowl or wide cup to whisk in, plus a teaspoon or small scale for dosing 1–2 g.
If you already own a milk frother for your cappuccino, you are fully equipped.
Step by Step: Classic Hot Matcha
- Sift 1–2 g of matcha (about half to one level teaspoon) through a fine sieve into your bowl. Don't skip this – matcha clumps naturally because the powder is so fine.
- Heat water to 70–80 °C – not boiling. Easiest trick without a thermometer: boil the kettle, then let it sit for two to three minutes or add a splash of cold water.
- Pour about 60–80 ml of the water over the powder.
- Whisk in a W shape – not in circles – until a fine layer of foam forms. With a chasen that takes roughly 20–30 seconds; an electric frother does it in a few.
- Top up with more hot water for a classic matcha, or with warm frothed milk for a matcha latte – done.
Iced Matcha Latte
The iced version is even more forgiving, because cool water makes bitterness almost impossible:
- Sift 2 g of matcha into a bowl and add about 60 ml of cool water.
- Whisk until smooth and slightly frothy.
- Fill a cup with ice cubes and about 200 ml of cold milk of your choice.
- Pour the matcha over the top – and enjoy the green swirl before you stir.

Common Mistakes & Fixes
Almost every disappointing matcha comes down to one of three causes – all of them quick to fix:
| Problem | Likely cause | Fix |
|---|---|---|
| Lumpy | Powder wasn't sifted | Always sift first, then whisk vigorously in a W shape |
| Bitter | Water too hot or too much powder | Stay at 70–80 °C and stick to 1–2 g per serving |
| Thin and watery | Too little powder or over-diluted | Dose properly and add water or milk gradually, tasting as you go |
And if your matcha tastes flat despite perfect technique, the powder itself may be old – matcha loses aroma quickly once opened, so keep it sealed, cool and away from light.
Matcha To Go
Matcha and an insulated cup are a natural match. Whisk your matcha or matcha latte at home, pour it into the 350 ml HEY SAHNI cup – double-wall vacuum insulated, it keeps drinks hot for up to 8 hours and cold for up to 12 – and your iced matcha survives the commute with the ice still intact.
The spill-proof sliding lid keeps everything where it belongs while you walk. One honest note: as with any milk drink, enjoy a matcha latte within a few hours – insulation extends freshness, it does not replace a fridge.
And if you want to pour a little leaf on top before you close the lid, here is our guide: How to Make Latte Art – everything in it works for matcha lattes too.
FAQ
How much caffeine does matcha have compared to coffee?
Per serving, roughly comparable to an espresso – depending on how much powder you use. Many people describe the effect as gentler and more even than coffee, which is commonly attributed to the amino acid L-theanine in green tea. As always, individual experience varies.
Why does my matcha taste bitter?
Almost always one of two reasons: the water was too hot or you used too much powder. Stay at 70–80 °C – never boiling – and stick to 1–2 g per serving. Quality matters too: good matcha tastes naturally sweet and grassy, not harsh.
Which matcha grade should I use for lattes?
Ceremonial grade is made for drinking pure with water. For lattes, a good culinary or latte grade is ideal – its stronger, more robust flavour stands up to milk, and it typically costs noticeably less.
Can I make a matcha latte with plant milk?
Absolutely – oat milk is especially popular because its natural sweetness pairs beautifully with matcha. Barista versions froth best. Soy and almond work too; just whisk the matcha in water first and add the milk afterwards.
