What is 'micron-grade' matcha? Does it significantly affect the mouthfeel?

What is "Micro-Powder Grade" Matcha?

Micro-powder grade matcha refers to a high-grade matcha with extremely fine powder particles, typically measuring below 10 microns in diameter (equivalent to 1/10th the width of a human hair). This matcha is finely ground using a specialized stone milling process and belongs to the category of premium tea ceremony tea. Compared to regular matcha, the micro-powder grade emphasizes superior powder uniformity and purity, better preserving the tea's natural color, aroma, and nutritional components.

Its Impact on Taste

• Enhanced Smoothness: The ultra-fine powder of micro-powder grade matcha dissolves completely in water, significantly reducing graininess and creating a smoother, more velvety mouthfeel in the tea liquor.
• Increased Flavor Intensity: Due to the increased surface area of the powder, flavor compounds like amino acids and catechins are released more readily, resulting in a richer, more refreshing taste with reduced bitterness.
• Improved Solubility: The high fineness allows for easier stirring and emulsification, preventing clumping or sedimentation and ensuring a consistently uniform tea liquor.
• Optimized Overall Experience: In the tea ceremony, micro-powder grade matcha provides a more refined drinking experience, highlighting matcha's umami and lingering sweetness, making it ideal for enthusiasts seeking high-quality taste. However, note that excessive fineness may, in some cases, accelerate oxidation and affect freshness, so airtight storage is recommended.
