Finding Your Perfect Matcha-to-Water Ratio
The question of how much water to use for 1 tsp of matcha has no single answer, as the ideal ratio depends on the type of tea you want to make. The same amount of powder can produce a delicate, traditional bowl of thin tea, a rich, concentrated thick tea, or a base for a creamy latte. To perfect your preparation, it's essential to understand the different styles and their specific water requirements.
The Standard: Usucha (Thin Tea)
Usucha, or 'thin tea,' is the most common form of prepared matcha and is the perfect starting point for beginners. This style produces a vibrant green, frothy beverage with a balanced flavor that allows the natural umami and subtle sweetness of the tea to shine. The standard ratio for a traditional Usucha provides a cup that is neither too strong nor too weak, offering a smooth and refreshing taste.
For a standard 1 tsp (approximately 2 grams) of matcha, you will typically use between 2.5 and 3 ounces (70-80 ml) of hot water. The water temperature is also critical; aim for a temperature between 160°F and 175°F (70°C to 80°C) to prevent scorching the delicate powder and producing a bitter taste.
How to prepare Usucha:
- Sift the matcha: Using a fine-mesh strainer, sift 1 tsp of ceremonial grade matcha into your bowl (chawan) to remove any clumps.
- Add hot water: Pour in 2.5 to 3 ounces of water that has been heated to the ideal temperature.
- Whisk vigorously: Use a bamboo whisk (chasen) to whisk the mixture in a rapid 'W' or 'M' motion until a fine layer of froth forms on the surface.
- Enjoy immediately: Drink the tea while it is fresh to savor its rich flavor and foamy texture.
The Concentrated: Koicha (Thick Tea)
Koicha, or 'thick tea,' offers a much more intense, syrupy experience. This preparation is often reserved for formal tea ceremonies and requires a higher grade of ceremonial matcha to avoid overwhelming bitterness. The result is a smooth, velvety texture with a deep umami flavor and a lingering sweetness.
To make Koicha, you will use significantly less water for the same amount of powder. For 1 tsp (approximately 2 grams) of high-quality ceremonial matcha, use only 1 to 1.5 ounces (30-40 ml) of hot water. The water temperature should remain in the 160-175°F range, as higher heat would make the already concentrated tea undrinkably bitter.
How to prepare Koicha:
- Sift the matcha: Sift 1 tsp of premium, ceremonial-grade matcha into your bowl.
- Add hot water: Add 1 to 1.5 ounces of water at the correct temperature.
- Knead the mixture: Instead of whisking for foam, use the chasen to slowly and gently knead the matcha into the water, creating a thick, uniform paste-like liquid without bubbles.
The Modern Twist: Matcha Lattes
For those who prefer a creamy, milk-based beverage, the initial preparation for a matcha latte requires a concentrated base. This ensures the matcha flavor is strong enough to stand up to the addition of milk and sweeteners. For a latte, you start by making a concentrated shot of matcha, similar to the Koicha method but often with a slightly different ratio.
For 1 tsp of matcha, whisk it with just 2 ounces of hot water to create a smooth, clump-free paste. This base can then be combined with your favorite milk, whether hot or iced, to create a delicious, balanced drink.
How to prepare a Matcha Latte:
- Sift the matcha: Place 1 tsp of matcha into a cup.
- Make the concentrate: Add 2 oz of hot water (160-175°F) and whisk or mix vigorously to dissolve the powder completely.
- Add milk: Pour 6-8 ounces of steamed or cold milk over the matcha concentrate and stir to combine. Add a sweetener if desired.
Comparison of Water-to-Matcha Ratios
| Preparation Style | Matcha (per 1 tsp) | Water Amount | Resulting Flavor/Texture | Ideal Water Temp | Quick Prep Tools |
|---|---|---|---|---|---|
| Usucha (Thin Tea) | ~2 grams | 2.5 - 3 oz (70-80 ml) | Light, frothy, balanced, and fresh | 160-175°F (70-80°C) | Chasen, Chawan |
| Koicha (Thick Tea) | ~2 grams | 1 - 1.5 oz (30-40 ml) | Thick, smooth, velvety, intense umami | 160-175°F (70-80°C) | High-Grade Matcha, Chasen |
| Matcha Latte Base | ~2 grams | 2 oz (60 ml) | Concentrated shot, strong matcha flavor | 160-175°F (70-80°C) | Frother or Whisk |
Beyond the Basics: Temperature, Grade, and Technique
Your matcha experience is not solely defined by the ratio. Several other factors play a crucial role in the final flavor and texture. For example, using water that is too hot will destroy the delicate amino acids that give ceremonial matcha its nuanced sweetness, leading to a bitter, unpleasant brew. This is why precision in temperature is so important.
The grade of matcha you use also dictates the outcome. Ceremonial grade matcha is made from younger, more tender leaves and is meant to be consumed on its own, either as Usucha or Koicha. Culinary grade matcha, made from more mature leaves, has a bolder flavor profile that works well when mixed into lattes, smoothies, or baked goods. It’s important to match the grade to the intended use for the best results.
Technique is the final piece of the puzzle. Sifting the matcha powder is a non-negotiable step for a clump-free, smooth beverage. Furthermore, the whisking motion for Usucha—a vigorous 'W' or 'M' pattern—is designed to create a fine, creamy froth that improves mouthfeel and aroma. Koicha, in contrast, requires a slower, kneading motion to create its dense, velvety consistency.
By paying close attention to these details—ratio, temperature, grade, and technique—you can elevate your homemade matcha and truly appreciate this centuries-old tradition. It's a mindful process that offers not just a beverage, but a moment of tranquility and focus.

Conclusion
The ideal amount of water to use for 1 tsp of matcha is not a fixed measurement but a dynamic element based on the type of tea you wish to prepare. For a light, traditional Usucha, use 2.5-3 ounces of water; for an intense, thick Koicha, use just 1-1.5 ounces. For modern lattes, a 2-ounce base is ideal for blending with milk. Always use water between 160-175°F (70-80°C) and the appropriate grade of matcha for the best flavor and texture. By understanding these ratios and techniques, you can craft the perfect cup every time, tailored to your personal taste.
