How to Make Matcha at Home: Usucha, Koicha, and the Two Fixes That Solve Most Problems

The bitter bowl of matcha you remember almost certainly came from two mistakes, and they are the same two mistakes nearly everyone makes. The water was too hot. The powder was never sifted. Fix those and the drink that tasted like boiled grass turns creamy and sweet. Everything else in this guide is refinement on top of those two corrections.

What you actually need (and what you can skip)

Three things do the real work:

• A chawan, a wide bowl with room to whisk.
• A chasen, the bamboo whisk; 80 to 100 prongs is right for everyday thin tea.
• A fine-mesh strainer for sifting.

Nice to have, not essential: a chashaku, the bamboo scoop, holding roughly 1 gram. A regular teaspoon works fine. If you plan to make thick tea, you'll want your widest bowl, because koicha needs room for a kneading motion that a narrow cup won't allow (Senbird Tea).

The ten-second step almost everyone skips

Matcha clumps in the tin. Static and humidity pack it into tiny lumps that no amount of furious whisking will dissolve, and you end up chasing them around the bowl. Push the powder through a fine-mesh strainer first. It takes ten seconds and it is the single highest-return habit in matcha preparation.

Water temperature, and why it rules everything

Boiling water is the enemy. At 100°C it strips out the sweetness, and what's left is harsh and tannic. Heat above roughly 80°C is widely reported to flatten matcha's natural sweetness, though sources disagree on the precise threshold.

Aim for 75 to 80°C for thin tea and a touch lower, 70 to 75°C, for thick. No thermometer? Boil the water, then let it sit five to seven minutes, or add a small splash of cold water before you pour.

Usucha: the everyday bowl

This is the bowl you'll make most days.

1. Sift 2 grams of matcha (about one level teaspoon) into the bowl.
2. Add 70 to 80 ml of water at 80°C.
3. Whisk briskly in a W or M zigzag, not a circle, for 15 to 20 seconds.
4. Stop when a fine, even froth covers the surface and no clumps remain. The colour should read vibrant green (Senbird Tea, Best Matcha).

The zigzag matters. A circular stir aerates unevenly and leaves you with big bubbles instead of fine foam.

Koicha: the ceremony bowl

Thick tea is a different drink, and a different motion. This is the form served at the heart of a tea ceremony.

1. Sift 3 to 4 grams of matcha (about two teaspoons).
2. Add only 30 to 40 ml of water, slightly cooler at 70 to 75°C.
3. Knead slowly, circular and figure-eight, for 20 to 30 seconds. You are not whisking up froth. You are folding the powder into a smooth paste.
4. The target is a thick, paint-like or warm-honey consistency: glossy, no bubbles, no foam.

One warning. Koicha demands your best matcha. At this concentration any bitterness or astringency in a lower grade gets amplified, not hidden (Senbird Tea). Save the cheap tin for lattes.

Usucha vs koicha at a glance

	Usucha (thin)	Koicha (thick)
Matcha	2 g	3–4 g
Water	70–80 ml	30–40 ml
Temperature	80°C (176°F)	70–75°C (160–170°F)
Motion	Brisk W-whisk	Slow circular knead
Froth	Yes, fine foam	No, smooth and thick
Grade	Ceremonial or premium	Highest ceremonial only
Occasion	Daily	Ceremony, special

The mistakes, ranked

1. Water too hot. Bitter. Let the boil settle five minutes.
2. No sifting. Lumpy. Ten-second sift.
3. Stirring in circles. Uneven aeration. Switch to the W motion for usucha.
4. A bowl that's too narrow. No room to whisk. Use the widest one you own.

No chasen? Make a latte

For milk drinks, don't waste your finest ceremonial powder. Culinary or premium grade is the right call, since the nuance disappears the moment you add milk. Make a paste first: dissolve 1 to 2 grams of matcha in about 2 tablespoons of hot water, whisk smooth, then pour in your steamed milk. Roughly 1.5 to 2 grams per 180 to 240 ml of milk gives a clean, green-forward latte.

Which grade for which job is the whole subject of the buying guide. And if you're curious why the cheap latte powder still works while the expensive bowl rewards care, that's grades, explained.

Key facts

• Usucha: 2 g matcha, 70–80 ml water at 80°C, brisk W-motion whisk to a fine froth (Senbird Tea, Best Matcha).
• Koicha: 3–4 g matcha, 30–40 ml water at 70–75°C, slow knead to a smooth paste with no froth (Senbird Tea).
• Always sift the powder; clumps come from static and humidity and won't whisk out.
• Never use boiling water; heat above ~80°C is widely reported to reduce matcha's sweetness.
• For lattes use culinary or premium grade and make a paste before adding milk.
