Our Mountain Plantations: Where Premium Quality Begins
The vibrant emerald-green color and sweet, umami finish of Orisen Tea Matcha are not artificial. They are the direct result of strict horticultural management across our high-altitude tea plantations:
- Science of Shading (Tana Netting)We block up to 98% of sunlight using specialized shade-cloths. This forces the tea plant to hyper-produce chlorophyll and L-theanine, suppressing bitter catechins.
- Organic Soil CareRich mountain humus combined with custom organic compost fuels nitrogen absorption, laying the foundation for a round, creamy, and smooth mouthfeel.
- Strict Crop SeparationOur certified organic fields are protected from conventional farmlands by thick natural windbreaks to eliminate pesticide drift risks.
Our 5-Step Transparent Matcha Processing Journey
By integrating traditional steam-fixation with automated low-temperature milling, we preserve the delicate sensory assets of matcha at industrial-scale volumes.
Fresh Leaf Washing & Withering
Freshly harvested green tea leaves are washed and withered to achieve optimal moisture levels.
Steam Fixation & Cooling
High-temperature steaming stops oxidation within hours, locking in the vibrant green color.
Stem-Leaf Separation (Tencha)
Dried leaves undergo precise winnowing to remove coarse stems, leaving pure leaf flesh (Tencha).
Low-Temp Ball Grinding
Advanced octagonal grinding mills operate below 15°C to prevent oxidation, producing 5-10 micron powder.
Dust-Free Auto Packaging
Under Class 100,000 cleanroom standards, matcha is filled and nitrogen-flushed into custom packaging.
Our Sensory Evaluation & Quality Control Testing Lab
We believe that premium matcha is born from the harmony of sensory artistry and strict science. In our specialized Sensory Evaluation Tasting Room, every harvest batch is systematically inspected by certified tea masters.
Organoleptic Auditing
Rigorous checks on color greenness (L*a*b* values), foam density, silkiness, and the classic roasted nutty aroma.
Physical & Chemical Checks
Precise testing of moisture content (kept <5%), mesh particle size, and total ash levels for maximum shelf stability.

Answers to Common Wholesaler Concerns
What is your Minimum Order Quantity (MOQ)?
For standard bulk packaging (20kg carton/bag), our MOQ starts at 80kg. For private label custom packaging, the MOQ depends on the selected format, generally starting at 500 units.

Bulk raw materials are typically dispatched within 7–10 working days. Customized OEM label orders require about 15–20 working days, depending on packaging material readiness.
