Pick your bowl or mug size, choose usucha, koicha, a latte, or iced matcha, and set a strength. The recipe below updates instantly with exact matcha, water, and milk amounts, the right temperature, and a whisking timer sized to that preparation. No conversions, no guessing at "a splash" of water.
With loose-leaf teas you steep, then discard the leaves. Most of the leaf never ends up in your cup, and steep time gives you room to correct. Matcha is different because you are drinking the entire leaf: shade-grown tea, de-stemmed and stone-ground into a fine powder that is suspended in the water, not strained out. Every gram of powder you add is fully present in your cup. There is nowhere for a bad ratio to hide.
This is why the grade of leaf and the ratio of powder to water matter so directly. A fresh, high-quality matcha is naturally sweet and full of umami, so it stays pleasant across a wide range of strengths. Lower-grade or stale matcha is more bitter and astringent, which makes the ratio far less forgiving. Higher strengths genuinely require higher quality leaf.
Water temperature is equally unforgiving. Boiling water scalds the powder and flattens the L-theanine sweetness while extracting tannins aggressively, turning the cup bitter and harsh. The traditional range of 70–80 °C isn't aesthetic. It's chemistry.
Matcha's roots go back to powdered tea traditions in Song-dynasty China, refined over centuries in Japan into the whisked preparation and tea-ceremony culture it's known for today. That history is also why there's real technique behind something that looks simple: sifting to break up static-clumped powder, warming the bowl so it doesn't cool the water, and a brisk whisking motion that builds fine microfoam instead of big, uneven bubbles. None of it is fussy for its own sake. Each step solves a specific, repeatable problem, which is why it's worth getting the ratio and technique right instead of eyeballing it.

The everyday expression of matcha: light, frothy, and bright. Around 2 g of powder whisked briskly into 60–80 ml of 75–80 °C water until a fine layer of froth covers the surface. A simple chawan in a warm bowl is all you need.
Full usucha guide →The ceremonial extreme. Roughly double the powder and half the water of usucha (about 4 g kneaded slowly into 30–40 ml of slightly cooler water), producing a dense, glossy, almost paint-like tea. Quality here is non-negotiable: anything bitter becomes overwhelming at this concentration.
Full koicha guide →A small whisked concentrate of matcha and water, topped with steamed or cold milk. The milk softens the bitterness and mutes the tea, so lattes want more matcha per cup than straight usucha. They're also the most forgiving style for culinary-grade powder.
Full matcha latte guide →Whisk a strong concentrate in a little warm water, then pour it over a glass full of ice. Add milk for creaminess or keep it pure. The concentrate should taste slightly too strong on its own, because the melting ice will dilute it into balance.
Full iced matcha guide →For usucha, a good baseline is about 2 g of matcha (roughly one heaping teaspoon or two bamboo scoops) to 60–80 ml of water, around a 1:35 ratio. Koicha flips this dense: about 4 g to just 30–40 ml of water. For lattes, use 3–4 g whisked into a small water concentrate before adding milk. The calculator above adjusts these baselines for your cup size and strength preference.
Ceremonial-grade matcha is made from the youngest, first-harvest leaves, carefully shaded and stone-ground, giving a smooth, naturally sweet taste with plenty of umami. It's meant to be whisked with water and drunk straight. Culinary-grade uses later harvests and is bolder and more astringent, which actually helps it cut through milk, sugar, and batter. Drink ceremonial as usucha or koicha; save culinary for lattes, smoothies, and baking.
Aim for roughly 70–80 °C, hot but well below boiling. Boiling water scalds the fine powder, over-extracts bitter catechins, and flattens the sweet, savory amino acids (like L-theanine) that make good matcha taste good. If you don't have a variable kettle, just boil water and let it sit for two to three minutes, or pour it between two vessels a couple of times.
Clumping happens because matcha is so finely ground that static and humidity make the particles stick together. Sifting the powder into the bowl before adding water fixes most of it. Bitterness usually comes from water that's too hot, too much powder for the amount of water, or simply stale or low-grade matcha. Cooler water, a sifter, and fresher tea solve the vast majority of bitter, clumpy bowls.
A chasen is the traditional tool and still the best one: its ~80–100 fine tines break up clumps against the bowl and build a delicate, even microfoam. That said, a handheld milk frother or small blender does a perfectly respectable job, especially for lattes and iced matcha. Whichever you use, sift the powder first. No whisk fully rescues unsifted matcha.
Use more for a latte. Straight usucha only needs about 2 g because there's nothing competing with the tea. In a latte, milk proteins and fat mute matcha's flavor, so 3–4 g per cup keeps the tea from disappearing. Whisk it into 30–60 ml of water first so it disperses fully before the milk goes in.
Matcha's enemies are oxygen, light, heat, and moisture. As a ground powder it stales far faster than whole-leaf tea. Keep it in an airtight, opaque container in a cool, dark place, and try to finish an opened tin within four to eight weeks. Unopened tins keep well in the fridge or freezer; just let a chilled tin come fully to room temperature before opening so condensation doesn't ruin the powder.
