Matcha is a finely ground powder made from specially grown and processed green tea leaves. Unlike conventional tea where leaves are steeped and discarded, matcha is fully dissolved in water — meaning you consume the entire leaf with all its nutrients, antioxidants, and caffeine. Originating in Tang Dynasty China and perfected in Japan, matcha has become one of the world's most celebrated and versatile ingredients, used in traditional tea ceremonies, lattes, smoothies, desserts, and baking.
The Matcha Calculator helps you determine the exact amount of matcha powder and water for five preparation styles, taking into account the grade of matcha and the number of servings.
The preparation style fundamentally determines the ratio of matcha to water:
Usucha (Thin Tea, Traditional): The most common traditional preparation. Approximately 1.5–2g of matcha per 60–80ml of water at 70–80°C, whisked to a frothy, light consistency. Usucha is the style most people encounter in Japanese tea ceremonies and modern cafés. It has a bright, vegetal, slightly grassy flavor with natural sweetness.
Koicha (Thick Tea, Ceremonial): An intensely concentrated preparation using approximately 4g of matcha per 30–40ml of water at 65–70°C. The result is a thick, syrupy, very concentrated tea with a complex, deep umami flavor. Koicha requires ceremonial-grade matcha — culinary-grade matcha tastes harsh in this preparation. The whisk motion for koicha is a slow, rolling motion rather than the rapid whisking of usucha.
Matcha Latte: Uses approximately 2g of matcha per 30ml of water (to make a paste/concentrate) before being topped with steamed or frothed milk (150–200ml). The initial paste ensures the matcha dissolves fully without clumps before the milk is added.
Iced Matcha: Similar ratio to latte but the concentrate is poured over ice and cold milk or water. Using slightly cooler water (around 70°C) to make the concentrate preserves more volatile aromatics.
Matcha Grade matters significantly for flavor. Ceremonial grade matcha is made from the youngest, shaded tea leaves (tencha) with vibrant green color and smooth, umami-rich, mildly sweet flavor — ideal for drinking as tea. Culinary grade matcha is made from older leaves and is more bitter and less vibrant — fine for baking, smoothies, and lattes where the matcha competes with other flavors but less ideal for traditional tea.
The calculator applies per-serving dosing standards for each preparation style. Base doses: Usucha 1.5g, Koicha 4g, Latte 2g, Iced 2g, Cooking 3g. Water amounts: Usucha 70ml, Koicha 40ml, Latte 30ml (for paste), Iced 50ml. Temperature is set per style based on preservation of matcha's volatile compounds and optimal dissolution. Teaspoon equivalent uses 0.8g per level teaspoon of matcha as a reference. All values scale linearly with number of servings.
Matcha powder that is clumping can be sifted through a fine mesh sieve before measuring to ensure smooth dissolution. For usucha and koicha, use a chasen (bamboo whisk) for traditional preparation — the fine tines create the characteristic froth that characterizes high-quality matcha. For lattes, a milk frother or blender works well to emulsify the matcha paste with milk. If matcha tastes very bitter, reduce amount slightly or ensure water is not above 80°C.

Sift 1.5g ceremonial matcha into a warmed bowl. Add 70ml water at 75°C. Whisk in a rapid W or M pattern for 20–30 seconds until frothy. Serve immediately in the bowl.

Sift 4g matcha, add 60ml water at 80°C, whisk to a smooth paste. Divide into 2 cups, top each with 150ml steamed or frothed milk. Add sweetener if desired. Total preparation time: ~3 minutes.
Ceremonial matcha is made from the youngest, shade-grown leaves of the first harvest (ichiban-cha). It has vibrant green color, smooth texture, mild vegetal flavor, and rich umami. Culinary-grade matcha uses older leaves and later harvests, producing a more bitter, less vibrant product. Use ceremonial for drinking; culinary for cooking is fine.
A standard usucha serving (1.5g matcha) contains approximately 35–70mg of caffeine — similar to green tea or about half the caffeine in a cup of coffee. Unlike coffee, matcha caffeine is modulated by L-theanine, an amino acid that produces a calm, focused alertness without the jittery spike and crash.
A chasen is ideal for traditional usucha and koicha preparation, producing the characteristic froth and ensuring clump-free dissolution. However, a milk frother, small electric whisk, or even vigorous stirring with a fork can work for casual matcha lattes and iced matcha. For the best ceremonial experience, a chasen is recommended.
Common causes: water too hot (above 80°C), too much matcha powder, low-quality culinary-grade matcha used for drinking, or matcha that is stale. Use water at 70–80°C, reduce the dose slightly, and ensure you are using ceremonial or premium-grade matcha for drinking purposes.
Store matcha in an airtight container in the refrigerator or freezer, away from light and heat. Matcha oxidizes rapidly once opened, turning from vibrant green to dull olive-yellow and losing its flavor within weeks when stored at room temperature. Refrigerated in a sealed tin, matcha can stay fresh for 2–3 months after opening.
L-theanine is an amino acid concentrated in shaded tea leaves (the shading process increases L-theanine content). It promotes relaxed focus, reduces stress, and modulates the stimulant effects of caffeine. The caffeine + L-theanine combination in matcha is associated with sustained, calm alertness — distinct from coffee's sharper, more jittery stimulation.
Yes — matcha is widely used in Japanese confectionery (wagashi), ice cream, cake, cookies, smoothies, and noodles. For cooking applications, culinary-grade matcha is cost-effective and works well. Use ceremonial-grade only if the matcha flavor needs to be prominent and delicate, such as in no-bake desserts.
Matcha tends to clump due to its very fine particle size and hygroscopic nature. Pass the matcha through a fine mesh tea sieve directly into the bowl before adding water. This removes clumps and ensures smooth, lump-free dissolution. Skipping this step leads to visible clumps in your tea and uneven flavor distribution.
Usucha (thin tea) is made with ~1.5g per 70ml — frothy, light, and bright. Koicha (thick tea) uses ~4g per 35ml — thick, syrupy, deeply complex, and intensely concentrated. Koicha requires the highest grade matcha and is prepared with a slow, rolling whisk motion rather than rapid whisking. Both have specific roles in the Japanese tea ceremony (chanoyu).
Both are excellent. Hot usucha at 70–75°C highlights the umami and delicate floral notes. Iced matcha preserves bright, fresh flavors and is refreshing. Cold matcha is made by whisking into a small amount of cool or room-temperature water, then poured over ice. Cold brewing matcha overnight also produces a delicious, mellow result.
