How much matcha powder should I use per cup?

By FUJI ASAHIEN · 6 min read

The Short Answer

Use 1.5–2 g of matcha powder (about one chashaku scoop) per 60–80 ml of hot water for a standard cup. For a matcha latte, use the same amount with 40–50 ml of water, then top with 100–150 ml of milk.

The chashaku (bamboo tea scoop) is the traditional measuring tool for matcha — one rounded scoop equals approximately 1.5–2 g.

The two classic ratios: usucha and koicha

Traditional Japanese tea ceremony uses two distinct preparations, each with its own powder-to-water ratio. Both are worth knowing, even if you only ever make usucha at home — understanding the spectrum helps you dial in the right amount for your taste.

Usucha — Thin Tea

1.5–2g

per cup

+ 60–80 ml water (70–80 °C)

The everyday standard. Light, frothy, smooth — ideal for beginners and daily drinking. One chashaku scoop.

★ Recommended
2g
per cup
+ 70 ml water (75 °C)
The sweet spot for most people. Balanced umami, sweetness, and light bitterness. Full flavour without being too intense.

Koicha — Thick Tea

3–4g

per cup

+ 30–40 ml water (80 °C)

Dense, syrupy, intensely flavoured. Traditional ceremony preparation. Requires ceremonial-grade matcha and experienced technique.

First time making matcha?

Start with 1.5 g and 80 ml of water at 75 °C. This is on the lighter end of the usucha range and produces a smooth, approachable cup. Once you find it too mild, gradually increase the powder to 2 g and reduce the water to 60–70 ml for a fuller flavour.

How much matcha for each drink style

The right amount of matcha depends not just on your taste preference, but on how you are preparing the drink. Milk, ice, and other liquids all dilute the flavour, so the recipe changes accordingly.

Drink Style	Matcha	Liquid	Notes
Usucha (thin tea) Traditional	1.5–2 g	60–80 ml hot water 70–80 °C	Whisk vigorously in a W-shape until a fine foam forms. No added milk or sweetener.
Koicha (thick tea) Traditional	3–4 g	30–40 ml hot water 80 °C	Stir in slow circular motions — no foam intended. Requires ceremonial grade. Served with wagashi (Japanese sweets).
Matcha latte Hot	2 g	40–50 ml hot water + 120–150 ml warm milk	Whisk matcha with hot water first, then add steamed milk. Oat milk pairs especially well. Optionally sweeten with honey or syrup.
Iced matcha latte	2 g	50 ml hot water + 120–150 ml cold milk + ice	Dissolve matcha in hot water first, pour over ice, then add cold milk. Using hot water to dissolve prevents clumping even in a cold drink.
Iced matcha water	1.5–2 g	200–250 ml cold or iced water	Dissolve matcha in a small amount of hot water first, then add cold water and ice. Refreshing and low-calorie.
Matcha smoothie	1–2 g	Blended with fruit, milk, yoghurt	Other ingredients carry the flavour, so 1 g is often enough. Use culinary grade for cost-effectiveness in smoothies.
Baking / cooking	5–10 g per recipe	Incorporated into batter or dough	Sugar and fat mask bitterness, so culinary grade is ideal. Adjust to taste — a stronger flavour needs more powder.

For a matcha latte, always dissolve the powder in a small amount of hot water at 75 °C first — this prevents clumping and ensures a smooth, even flavour.

How to measure matcha accurately

Measuring matcha precisely makes a bigger difference than most people expect. Too little and the cup tastes weak and watery; too much and bitterness dominates. These are the two main tools:

🧁

Chashaku (bamboo tea scoop)

The traditional Japanese measuring tool. A single rounded scoop holds approximately 1.5–2 g of matcha. It is designed specifically for matcha's density, making it surprisingly accurate once you get a feel for a “rounded” vs “heaped” scoop. Available inexpensively online and in Japanese kitchenware shops. Ideal for daily use — quick, no clean-up, and part of the ritual.

Digital kitchen scale (0.1 g precision)

The most accurate method. A scale that reads to 0.1 g lets you dial in the exact amount for your preferred ratio. Especially useful when you are experimenting to find your sweet spot, or when making koicha where precision matters more. Once you know how a “perfect” scoop looks and feels, you can largely switch back to the chashaku for convenience without losing much accuracy.

A digital scale reading to 0.1 g is the most precise way to find your ideal matcha amount — especially useful when you are just starting out.

How the amount affects taste

Matcha's flavour is not simply “more powder = stronger taste.” The relationship between powder amount, water volume, and temperature determines which compounds dominate your cup. Here is what changes as you adjust the amount:

1 g

Too little — watery, pale, lacking depth

At 1 g per 80 ml, the cup is very light and lacks the umami character that makes matcha distinctive. The colour will be a pale, washed-out green. Fine for a very gentle introduction, but most people find it unsatisfying.

1.5 g

Light usucha — smooth and approachable

A pleasant, balanced cup with visible green colour and gentle sweetness. Good for beginners or for an afternoon cup when you want less caffeine. Best with 70–80 ml of water at 75 °C.

2 g

Standard usucha — the sweet spot

The most widely recommended ratio. Rich green colour, full umami, noticeable sweetness from L-theanine, and a pleasant light bitterness at the finish. Works equally well as a straight drink or as the base for a latte.

3–4 g

Koicha territory — intense and concentrated

Rich, almost syrupy consistency with a powerful umami and noticeable bitterness. Best made with a premium ceremonial grade. If you try this amount with a culinary grade, the bitterness will be overwhelming. Not for beginners.

5+ g

Too much — bitter and harsh

Beyond 4–5 g in a standard cup, bitterness overwhelms all other flavours regardless of water temperature. More powder also means more caffeine per cup — which at high amounts can cause jitteriness.

Common measuring mistakes to avoid

Using a teaspoon instead of a chashaku

A standard teaspoon holds approximately 2.5–3 g of matcha — significantly more than one chashaku scoop. If you have been using a teaspoon and finding matcha too bitter, switching to the correct amount may immediately solve the problem. A level half-teaspoon is roughly equivalent to one chashaku scoop.

Not sifting before measuring

Unsifted matcha can contain micro-clumps that make the measured weight inaccurate and create bitter pockets in the cup. Always sift matcha through a fine-mesh sieve before measuring and whisking, especially if the pouch has been open for more than a week.

Using too little water for the amount of powder

Adding 2 g of matcha to only 30–40 ml of water (instead of 60–80 ml) concentrates all the bitter compounds and makes whisking very difficult. If you want a stronger flavour, use more powder — do not simply reduce the water beyond the koicha range.

Assuming “more is better” for health benefits

Doubling the powder does not double the health benefits proportionally. At higher doses, EGCG intake becomes excessive and caffeine spikes. The optimal health-to-taste ratio sits right at 1.5–2 g per cup, not at higher amounts.

Quick reference card

Straight matcha (usucha): 2 g + 70 ml water at 75 °C • Matcha latte: 2 g + 50 ml water + 130 ml milk • Iced matcha: 2 g + 50 ml hot water + 150 ml cold milk or water + ice • Koicha: 3–4 g + 35 ml water at 80 °C

Start with the perfect ratio
