Matcha, a type of powdered green tea, has become increasingly popular due to its vibrant color, unique flavor, and health benefits. But have you ever wondered how matcha is made? The process is intricate and involves several steps to ensure the highest quality product. In this article, we will explore the art and process of matcha production, from the cultivation of matcha leaves to the final grinding.
Cultivating Matcha Leaves
The journey of matcha begins with the careful cultivation of matcha leaves. These leaves come from the Camellia sinensis plant, the same plant that produces other types of green tea. However, what sets matcha apart is the specific growing conditions and processing methods.
Shading the Plants
About three to four weeks before harvest, the tea plants are shaded to reduce direct sunlight. This is a crucial step in the production of matcha. Shading the plants slows down their growth and increases the chlorophyll content in the leaves, giving them a darker green color. This also boosts the production of amino acids, particularly L-theanine, which contributes to matcha’s unique umami flavor.
Harvesting the Leaves
The timing of the harvest is critical. The youngest, most tender leaves are hand-picked to ensure the highest quality. These leaves are known as “tencha” and are the only leaves used to make matcha.
Processing the Leaves
Once the leaves are harvested, they undergo several processing steps to transform them into the fine powder known as matcha.
Steaming
Immediately after harvesting, the leaves are steamed to prevent oxidation and preserve their vibrant green color. Steaming also helps to retain the nutrients and flavor of the leaves. This step is similar to the process used for other types of green tea, but it is particularly important for matcha to maintain its quality.
Drying
After steaming, the leaves are dried to remove any remaining moisture. The drying process can vary, but it typically involves air-drying the leaves in a controlled environment. This ensures that the leaves do not become brittle and lose their flavor.
De-stemming and De-veining
Once dried, the leaves are carefully de-stemmed and de-veined. This means removing any stems and veins from the leaves to ensure a smooth texture in the final product. This step is labor-intensive but crucial for producing high-quality matcha.
Specific proportions of tencha will be mixed according to the tea masters’ subsequent instructions and stored away.

Grinding the Leaves
The final step in matcha production is grinding the processed leaves into a fine powder. This is where the transformation into matcha truly occurs.
Traditional Stone Grinding
Traditionally, matcha is ground using granite stone mills. This method is slow and laborious, but it produces the finest and most consistent powder. The grinding process can take up to an hour to produce just 30 grams of matcha. The slow grinding helps to prevent overheating, which can degrade the quality of the powder.
Modern Grinding Methods
In addition to traditional stone grinding, modern methods such as ball mills and jet mills are also used. These methods are faster and can produce larger quantities of matcha. However, they may not achieve the same level of fineness and consistency as stone grinding.
Quality Control
Throughout the entire production process, quality control measures are in place to ensure that the matcha meets high standards. This includes checking the color, aroma, flavor, and texture of the powder. High-quality matcha should have a bright green color, a fresh and grassy aroma, a sweet and umami flavor, and a fine, smooth texture.
Different Grades of Matcha
Matcha is typically categorized into two main grades: ceremonial grade and culinary grade.
Ceremonial Grade
Ceremonial grade matcha is the highest quality and is used in traditional Japanese tea ceremonies. It is made from the youngest, most tender leaves and has a vibrant green color, smooth texture, and a delicate, sweet flavor. This grade of matcha is best enjoyed on its own, whisked with hot water.
Culinary Grade
Culinary grade matcha is slightly lower in quality compared to ceremonial grade but is still excellent for various uses. It is made from slightly older leaves and has a more robust flavor, making it ideal for cooking and baking. This grade of matcha is often used in lattes, smoothies, and desserts.
Health Benefits of Matcha
Matcha is not only delicious but also packed with health benefits. It is rich in antioxidants, particularly catechins, which help to protect the body from free radicals. Matcha also contains L-theanine, an amino acid that promotes relaxation and reduces stress. Additionally, matcha provides a gentle and sustained energy boost without the jitters often associated with coffee.
Tea processors will now sort them into containers according to color, texture, and aroma; and will add in hot water to the tencha to grade the quality of the tea.
How to Prepare Matcha
Preparing matcha is an art in itself. Here is a simple guide to making a traditional bowl of matcha:
- Sift the Matcha: Use a fine mesh sieve to sift 1-2 teaspoons of matcha into a bowl. This helps to break up any clumps and ensures a smooth texture.
- Add Water: Pour about 2 ounces of hot water (not boiling, around 175°F) into the bowl.
- Whisk: Use a bamboo whisk (chasen) to whisk the matcha in a zigzag motion until it becomes frothy.
- Enjoy: Sip and savor the unique flavor and aroma of your matcha.
Conclusion
The art and process of matcha production is a fascinating journey from leaf to cup. From the careful cultivation and shading of matcha leaves to the meticulous grinding and quality control, each step is essential in producing the vibrant green powder that many have come to love. Whether you enjoy it in a traditional tea ceremony or as an ingredient in your favorite recipes, matcha offers a unique and delightful experience.
By understanding how matcha is made, you can better appreciate the craftsmanship and dedication that goes into producing this exquisite tea. So the next time you sip on a bowl of matcha, take a moment to savor the rich history and intricate process behind this extraordinary beverage.
