From leaf to powder: the making of matcha

Matcha is much more than just powdered green tea—it embodies a centuries-old craftsmanship deeply rooted in Japan. Behind every scoop of matcha lies a meticulous process that makes it truly exceptional. From the cultivation of the leaves to the fine grinding process, let's dive into the journey of how matcha is made.

 

Shaded cultivation to enhance flavor

It all begins in the tea fields, primarily in the renowned regions of Kyoto and Kagoshima, known for producing high-quality tea. Unlike other green teas, matcha leaves are shade-grown for about three weeks before harvest.

This shading process has a direct impact on the tea’s taste and composition:

• The plant produces more chlorophyll, giving the leaves their vibrant green color.
• The level of L-theanine (an amino acid promoting relaxation) increases, contributing to matcha’s smooth and balanced flavor.
• Tannin levels decrease, reducing bitterness.

 

A carefully selected harvest

When the time is right, only the youngest and most tender leaves are harvested, either by hand or machine, depending on the desired quality. These leaves, known as tencha, are then quickly steamed to halt oxidation, preserving their color and delicate flavors.

 

Drying and precise sorting

After steaming, the leaves are dried and meticulously stripped of stems and veins, leaving only the most precious part of the leaf. This process ensures an ultra-fine texture and prevents excessive bitterness.

 

Stone grinding for ultimate fineness

This is the most iconic step: the traditional stone grinding using granite mills. Though slow (producing only 30 to 40 grams of powder per hour), this method is essential for achieving a silky texture and perfect solubility in water.

Unlike industrially processed powders, this grinding technique preserves the full depth of flavors and results in an incredibly fine texture (5 to 10 microns, even finer than flour!).

 

Packaging to preserve freshness

Once ground into a fine powder, matcha is immediately sealed in airtight containers to protect its flavor and prevent oxidation. Exposure to air, light, and humidity could degrade its delicate taste and nutritional properties.

 

A true craft in every cup

Every step in the production of matcha contributes to its unique flavor and benefits. From its shaded cultivation to its traditional grinding and careful packaging, matcha is a tea that perfectly balances tradition and quality.

Sipping a cup of matcha means experiencing not only an exceptional tea but also the legacy of refined Japanese craftsmanship.
