Matcha’s Worst Enemies: Heat, Light, and Oxygen
Unlike robust black teas, matcha is incredibly delicate. Once the tencha leaves are stone-ground into a fine powder, the surface area increases exponentially, making the tea highly susceptible to oxidation. Exposure to heat, UV light, or oxygen will rapidly degrade the vibrant green color into a dull yellow and turn the sweet umami flavor bitter.Export Logistics Best Practices
To maintain ceremonial quality during international shipping, several precautions are mandatory: 1. Nitrogen Flushing: Before sealing, premium matcha bags must be flushed with nitrogen to remove all oxygen. 2. Opaque, Airtight Packaging: The powder must be sealed in heavy-duty, light-blocking foil pouches. 3. Temperature Control: While matcha does not require the strict 0°C cold chain of Wagyu beef, it should absolutely be shipped via air freight to minimize transit time, and stored in cool, climate-controlled environments away from direct heat sources.Wagyu Ninja’s Quality Guarantee
