Matcha quality guide: How to choose good matcha

The origin

​Matcha is deeply rooted in Japanese tea culture, where cultivation and processing techniques have been refined over generations. Different growing regions have their own climates, soils, traditions and tea-producing expertise. Kyoto, Aichi, Shizuoka and Kagoshima are among the areas known for Japanese tea production. However, the region alone does not determine quality. The producer, farming practices and processing techniques are equally important.

At 6:30am, our matcha comes from Aichi.

 

​

​The harvest

Tea plants produce new growth throughout the growing season, but not every harvest has the same characteristics.

The first harvest, known as ichibancha, is particularly appreciated for its young, tender leaves and often delicate flavour profile.

Later harvests can produce teas with different levels of bitterness, astringency and intensity.

Neither is automatically unsuitable. The ideal choice depends on how the matcha will be used. However, for premium matcha designed to be enjoyed on its own, the first harvest is often preferred.

At 6:30am, we source exclusively from first-harvest (ichibancha) tea leaves each year.

​​

Cultivars​​​

A cultivar is a cultivated variety of the tea plant. Just as different grape varieties produce different wines, different tea cultivars can influence the flavour, aroma, colour and texture of matcha.

Some cultivars are known for their umami-rich profiles, while others can bring freshness, sweetness or more pronounced vegetal notes.

Yabukita, Saemidori, Okumidori and Gokou are examples of cultivars used in Japanese tea production.

Blending cultivars can also be a deliberate choice, helping producers achieve a particular flavour profile and consistency. A good matcha should be selected for how it tastes, not simply for the name of its cultivar.

At 6:30am, our tins feature single-cultivar Saemidori matcha, while our 50g pouches offer a blend of Yabukita and Okumidori cultivars.

Organic: understanding what it means​

Organic certification concerns how tea is cultivated and processed under defined production standards. It regulates the use of certain agricultural inputs and requires compliance with specific certification rules. Choosing certified organic matcha provides an additional level of transparency about production practices. However, organic certification is not, by itself, a guarantee of exceptional flavor.

A great matcha depends on a combination of responsible cultivation, carefully selected leaves and precise processing.

At 6:30am, we choose certified organic Japanese matcha.

​

Color, aroma and taste​

Color: High-quality matcha often displays a vibrant, natural green colour.

A dull or yellowish appearance may be associated with ageing, oxidation, leaf characteristics or processing differences. Color alone, however, is not enough to judge quality.

Aroma: Fresh matcha can have delicate vegetal, sweet and sometimes subtly savoury aromas.

An unpleasantly stale or flat aroma may indicate that the product has lost freshness.

Taste: A good matcha should offer balance.

Look for a pleasant combination of umami, natural sweetness and controlled bitterness.

It should be enjoyable with water alone, even if you usually prefer a latte.

Texture: Finely milled matcha should feel smooth and delicate.

When whisked correctly, it should form an even suspension with a pleasant mouthfeel.​

​

What about ceremonial grade?

You've probably seen the terms ceremonial grade and culinary grade.

Although commonly used outside Japan, these are not official Japanese government quality certifications.

They are generally commercial descriptions used to indicate how a particular matcha is intended to be enjoyed.

Ceremonial usually suggests a matcha suitable for drinking with water, while culinary generally refers to products intended for cooking or mixing.

Rather than relying on these terms alone, look at the actual details: origin, harvest, cultivar, processing, freshness and taste.

 

​

Freshness and storage

Matcha is a delicate product.

Exposure to light, heat, air and moisture can affect its color, aroma and flavor over time.

To preserve its quality:

- Keep it in its original, tightly closed packaging or an airtight container.

- Store it away from direct sunlight, heat and humidity, preferably in the fridge.

- Use clean, dry utensils.

- For optimal freshness, enjoy within three months of opening.

 

​

Quality is in the details
