The Origins of Matcha Tea
Historical Background of Matcha
Matcha tea has a rich history that dates back to the 1100s. It was introduced to Japan by a Zen Buddhist monk who brought tea seeds from China. This monk established a practice that would eventually become a significant part of Japanese culture. Over the centuries, matcha evolved from a simple tea to a ceremonial drink, deeply embedded in Japanese traditions.
Cultural Significance in Japan
In Japan, matcha is more than just a beverage; it is a symbol of mindfulness and respect. The Japanese tea ceremony, known as “chanoyu,” is a ritualistic preparation of matcha that emphasizes harmony, respect, purity, and tranquility. This ceremony is not just about drinking tea but also about appreciating the moment and the company of others.
Introduction to Camellia Sinensis
Matcha comes from the Camellia Sinensis plant, the same plant used for other types of tea like black, oolong, and regular green tea. However, what sets matcha apart is its unique cultivation and processing methods. The leaves are shaded before harvest to increase chlorophyll levels, giving matcha its vibrant green color and rich nutrient content.
Selecting the Right Tea Plants
Choosing the right tea plants is crucial for producing high-quality matcha. Not all tea plants are suitable, and the selection process involves understanding different varieties and specific criteria for matcha-grade leaves.
The Importance of Shading
Shading the tea plant from sunlight is easily the most critical part of the matcha production process. It greatly affects the taste of the final matcha powder and takes great skill and knowledge to do correctly. With less sunlight for photosynthesis, the tea plant begins various chemical reactions that increase the production of various amino acids. These amino acids contribute to the sweet, umami flavors in matcha, and is also responsible for some of the desirable compounds in matcha like L-theanine.
Harvesting Matcha Leaves
Harvesting matcha leaves is a crucial step in the journey from plant to powder. The timing, method, and initial quality assessment all play significant roles in determining the final product’s quality.
Optimal Harvesting Time
The best time to harvest matcha leaves is typically around May each year. This period is known as the First Harvest or First Flush. The leaves collected during this time are rich in nutrients accumulated over the growing season. Some farmers may choose to harvest only once a year to ensure the highest quality, while others may have multiple harvests, including a second and third flush.
Hand-Picking vs. Machine Harvesting
In Japan, tea leaves are harvested both by hand and by machine. Hand-picking is often preferred for smaller fields and is believed to result in superior tasting tea. However, machine harvesting is more common in larger fields and can be just as effective if done correctly. In regions with uneven terrain, handheld devices similar to large lawn trimmers are used to rake over the tea plants.
Initial Quality Assessment
Once harvested, the tea leaves undergo an initial quality assessment. This step is vital to ensure that only the best leaves proceed to the next stages of processing. The leaves are quickly steamed within 24 hours of harvesting to preserve their color and nutrients and to prevent oxidation.
Steaming and Drying the Leaves
Once the matcha leaves are harvested, they immediately undergo a steaming process. This step is crucial as it prevents oxidation, ensuring the leaves retain their vibrant green color and high levels of amino acids. The steaming process typically lasts for about 20 seconds.
Purpose of Steaming
Steaming the leaves halts oxidation, which is essential for preserving the flavor and nutrients. This step is unique to Japanese tea production and sets it apart from other types of tea, which often allow oxidation to occur.
Drying Techniques
After steaming, the leaves are air-dried using blowers to remove moisture. This helps in maintaining the quality and extending the shelf life of the tea. The leaves are then further dried in large ovens to ensure they are completely moisture-free.
Preventing Oxidation
The combination of steaming and drying is designed to stop the leaves from oxidizing. This is vital for keeping the leaves’ color and nutritional content intact. The result is a product that can be stored for longer periods without losing its quality.
Transforming Leaves into Tencha
What is Tencha?
After the tea leaves are steamed and dried, they go through a process to become tencha. This involves removing the stems and veins from the leaves. The result is a leaf that is flat and flaky, perfect for grinding into matcha.
De-stemming and De-veining
The leaves are passed through machines that separate the stalks and veins from the tea leaf. This step is crucial because the stalks are considered a waste product. The process is repeated several times to ensure all stalks are removed. Once this step is completed, the leaves are called aracha, or crude tea.
Quality Control Measures
Aracha is sent to another set of machines for further refinement. These crude tea leaves pass through several rounds of sifting to remove smaller impurities. The leaves are then cut into smaller pieces, transforming aracha into tencha. At this point, a tea master samples the tencha to appraise its quality. The tea master may blend different tencha together to create desirable flavors. Specific proportions of tencha are mixed according to the tea master’s instructions and stored away.
The complex and rigorous process of transforming leaves into tencha is what makes matcha so unique and highly-prized.
Grinding Tencha into Matcha
Traditional Stone Mills
The pure leaves, known as tencha, are ground into a fine powder using a traditional granite stone mill. This slow, detailed process is essential for producing the fine, vibrant green matcha powder. It takes an hour for a traditional granite stone mill to grind 30 to 40 grams of matcha. Faster grinding would burn and spoil the leaves. The stone mill maintains a low speed and temperature, ensuring that the matcha does not lose its color and nutritional properties during grinding.
Modern Grinding Techniques
Larger producers often use jet mills or ball mills instead. These machines are more efficient, but some believe they result in a different, less desirable texture. The most advanced jet mill machines can grind to micron sizes comparable to stone mills. The important question to ask is whether the texture of the matcha feels soft and airy, like talcum powder. Between the modern milling machines and the traditional stone mill, only experienced matcha fans would be able to tell the difference.
Ensuring Fine Powder Consistency
The particle size of matcha powder is vital. High-quality matcha should have a balanced flavor profile, achieved by a balanced mix of particle sizes in the ground tea powder. Authentic matcha producers set the speed of their stone grinders at the optimal range, usually 48 revolutions per minute. Each stone grinder produces only 30 grams of matcha per hour. This meticulous process ensures that the matcha has a super fine texture, similar to baby powder.
The process of creating fine and high-quality matcha reminds us that it is an art of its own.
Quality Assessment by Tea Masters
Role of the Tea Master
Tea masters are the heart and soul of matcha production. They dedicate their lives to Japanese tea and use all their five senses to produce the best Japanese tea. Their expertise ensures that only the finest matcha reaches your cup. They evaluate the color, aroma, and texture of the tea leaves, making sure each batch meets high standards.
Blending Different Batches
Blending is an art. Tea masters mix leaves from different harvests to create a balanced flavor. This process requires a deep understanding of how various leaves interact. The goal is to achieve a consistent taste, color, and aroma in every tin of matcha.
Final Quality Checks
Before matcha is packaged, it undergoes final quality checks. Tea masters inspect the powder for any impurities and ensure it has the right consistency. This step is crucial to maintain the high quality of matcha you expect.
