Complete guide to Japanese matcha: origin, preparation, and benefits

Japanese matcha is powdered green tea made from tencha, but its quality and taste depend on far more than colour alone. Origin, cultivar, shading, harvest, processing, grinding, freshness and storage all influence what ends up in the cup.

This guide covers the essentials: how matcha is made, how to judge quality, how to prepare it, how to choose it for different uses and how to store it correctly.

What is Japanese matcha?

Matcha is produced from tea leaves grown for tencha. Before harvest, the plants are shaded, then the leaves are steamed, dried and refined. Stems and veins are removed before the tencha is ground into a very fine powder.

Because the powder itself is consumed, matcha behaves differently from an infused tea. It does not truly dissolve like sugar: fine particles remain suspended in the drink.

Where does matcha come from?

Japan has several important tea-producing regions, each with its own climate, cultivars and production traditions. Maison Yume focuses on Yame, in Fukuoka Prefecture, a region known for high-quality Japanese tea.

Maison Yume works directly with a family farm in Yame, which gives the brand a clear and traceable sourcing relationship without relying on vague origin claims.

How is matcha made?

1. Shading: tea plants are shaded before harvest.
2. Harvest: leaves are picked according to the desired profile and quality.
3. Steaming: heat stops oxidation soon after harvest.
4. Drying and refining: the leaves are dried and stems and veins are removed to create tencha.
5. Grinding: tencha is milled into a very fine powder.

Each step affects aroma, texture, colour and balance.

How to recognise good matcha

No single visual test can prove quality. Evaluate several criteria together:

• Origin and traceability: a precise Japanese origin is more useful than a generic claim.
• Aroma: good matcha should smell fresh and clean, not dusty or stale.
• Texture: a fine powder disperses more evenly and feels smoother.
• Colour: vivid green can be a positive signal, but lighting and photography can be misleading.
• Taste: balance matters more than extreme intensity. Depending on the product, look for umami, sweetness, freshness and controlled bitterness.
• Freshness and storage: heat, light, moisture and oxygen quickly degrade matcha.

How to choose matcha by use

The most useful question is not “which grade is highest?” but “what do I want to make?”

Pure with water

Choose a smooth, fine and balanced matcha that remains pleasant without milk or sugar.

Matcha latte

Choose a matcha with enough aromatic intensity to remain present once milk is added. Test the exact milk and final drink size you intend to use.

Baking and pastry

Choose a matcha whose flavour and colour remain visible after mixing with sugar, fat, cream or chocolate. In professional recipes, cost per serving is often more useful than price per kilogram.

How to prepare matcha

A reliable starting point for a simple cup is:

• 1.5 to 2 g matcha;
• 60 to 80 ml water;
• water around 70–80°C;
• a fine sieve and a chasen, small whisk or suitable frother.

1. Sift the powder.
2. Add the water.
3. Whisk quickly until the drink is homogeneous and lightly foamed.
4. Drink soon after preparation.

For more detail, see our matcha preparation guide.

How much matcha for a latte?

For most lattes, 2 to 2.5 g is a useful starting point with roughly 150 to 180 ml of milk. Larger or iced drinks may need adjustment because milk and melting ice reduce perceived intensity.

Why water temperature matters

Very hot water can emphasise bitterness and astringency. Around 70–80°C is a practical starting range for many matchas. Learn more in our guide to matcha water temperature.

How to store matcha

Protect matcha from heat, light, air and moisture. Close the packaging carefully after use and avoid repeated exposure to warm, humid environments.

For professional stock management, Maison Yume recommends refrigerated storage between -5 and 5°C. Allow a sealed package to adjust toward room temperature before opening when needed, which helps reduce condensation risk.

Maison Yume matcha from Yame

Maison Yume matcha from Yame is selected for a smooth, low-bitterness profile with rich umami, good aromatic intensity and a slight chocolate note. It is versatile enough for water, lattes and pastry applications.

FAQ

Is matcha an infusion?

No. Matcha is a fine tea powder dispersed in water, so the leaf itself is consumed.

Does good matcha have to be completely non-bitter?

No. A slight bitterness can be normal. What matters is that it remains balanced rather than harsh or dominant.

How much matcha should I use?

For a simple cup, start around 1.5 to 2 g. For a latte, 2 to 2.5 g is a useful starting point.

Can one matcha work for both water and lattes?

Yes. A balanced matcha with sufficient aromatic intensity can be versatile across both uses.
