Introduction to Matcha Processing

Matcha, a tea tradition that originated in China's Tang Dynasty and flourished in Japan, has become a global wellness phenomenon. Yet, few consumers realize that the grinding method directly impacts matcha's quality, taste profile, and nutritional value.

For C-end consumers seeking premium lifestyle products, understanding matcha processing enables informed purchasing decisions. For B-end clients focused on cost-effectiveness and product consistency, selecting the appropriate processing method is crucial for brand reputation and profit margins.

The Craft: Stone Mills vs. Machine Grinding

The Art of Traditional Stone Milling

Stone milling (Ishi-Usu) represents centuries of perfected craftsmanship, utilizing granite mills rotating at precisely 3 seconds per revolution.

Advantages:

Low-temperature processing: Preserves 98% of chlorophyll and amino acids by avoiding heat damage
Uniform particle size: Creates ultra-fine 15-micron powder for silky smooth texture
Unique flavor profile: Develops distinctive "hika" aroma, adding warm complexity
Vibrant color: Maintains brilliant jade-green hue with strong visual appeal

Limitations:

Limited capacity: Produces only 40-50g per hour, challenging large-scale production
Higher costs: Processing cost approximately $1.5 per kilogram
Microbial concerns: Open environment may harbor higher microbial content

Modern Machine Grinding Efficiency

Machine grinding, primarily using ball mill technology, crushes tencha leaves through impact and extrusion.

Advantages:

High efficiency: Produces 1+ kg per hour, meeting industrial demands
Cost-effective: Processing cost only $0.15 per kilogram
Sealed environment: Lower microbial contamination risk, enhanced food safety
Consistency: Controlled 5-10 micron particle size ensures stable quality

Challenges:

Temperature control: Heat generation may affect color and flavor
Nutrient loss: Some chlorophyll may degrade during processing
Texture differences: May create slight graininess affecting premium experience
