How do you make matcha at home without it being bitter or lumpy?
Quick answer
Sift 2 g of matcha into a bowl, add a little 80 °C water (never boiling), and whisk briskly in a "W" or "M" motion — not circles — until a fine foam forms. Then top up to taste. Boiling water and unsifted powder are what cause bitterness and lumps; cooler water and a quick sift fix both.
Step by step
- Sift the powder. Push 1–2 g of matcha through a small strainer into a wide bowl. This breaks up clumps — the single best anti-lump step.
- Cool the water. Boil, then let it sit ~2 minutes to reach roughly 80 °C. Boiling water scorches matcha and turns it bitter.
- Add a splash first. Pour in just 15–20 ml and whisk that into a smooth paste — easier to break up than a full bowl.
- Whisk to foam. Add the rest (about 60–70 ml total), then whisk fast in a W or M shape from the wrist for 15–20 seconds until a fine layer of foam sits on top.
- Top up or add milk. Drink as is (usucha), or pour over cold milk for a latte.
Usual mistake vs the fix
| Common mistake | The fix | |
|---|---|---|
| Water | Boiling, straight off the kettle | Cooled to ~80 °C |
| Powder | Spooned in dry, unsifted | Sifted to remove clumps |
| Motion | Slow circles | Brisk W/M from the wrist |
| Ratio | Guessed by eye | ~2 g to 60–70 ml |
| Grade | Culinary, drunk straight | Ceremonial for drinking |
How much matcha per cup?
A drinkable baseline is 2 g (about one heaping ½-teaspoon) to 60–70 ml of water for a small, strong bowl, or top up to ~120 ml for a lighter cup. For a latte, keep the matcha and hot water the same and add 120–180 ml of milk. Scale it precisely with the grams calculator.
Common questions
Why is my matcha bitter? Almost always water that's too hot. Let the kettle cool for a couple of minutes — aim for about 80 °C, not a rolling boil.
Why is it lumpy or gritty? The powder wasn't sifted, or it was whisked too gently. Sift first, make a paste with a little water, then whisk hard.
Can I use culinary matcha to drink? You can, but it's made to stand up to milk and sugar and tastes sharper straight. For a plain bowl, ceremonial grade is smoother — see ceremonial vs culinary matcha.
