Gui Tea Group
Gui Tea Group presentation
Gui Tea Group stands as China’s largest matcha producer and a nationally recognized leader in agricultural enterprise. Founded in April 2010 in Guizhou Province, the company operates the world’s largest single-site matcha factory with an impressive annual production capacity exceeding 4,000 tonnes. This scale positions Gui Tea as a dominant force in global matcha supply, particularly serving markets across Japan, the United States, Germany, and 40+ other countries.
From Plateau to Powder: The Guizhou Advantage
The company’s tea gardens sprawl across 140,000 mu (approximately 9,300 hectares) in Guizhou’s misty highlands, where elevation reaches 1,000 meters above sea level. This unique terroir creates ideal conditions for premium tea cultivation—high altitude, low latitude, abundant cloud cover, and minimal pollution. The region’s pristine environment has earned recognition as an emerging powerhouse in shade-grown tea production.
Gui Tea manages over 60 tencha processing lines that combine traditional Japanese techniques with fully automated intelligent production systems. Their ceremonial-grade matcha undergoes 20 days of shade-growing before harvest, steam sterilization in Tang and Song Dynasty fashion, and ultra-fine grinding to 1,300-mesh (11 µm)—significantly finer than standard matcha powder.
Meeting the Highest Global Standards
Quality assurance defines Gui Tea’s reputation. Every product passes over 480 pesticide residue tests and meets stringent EU export standards. The company holds multiple international certifications including USDA Organic, EU Organic, HACCP, ISO 22000, FSSC22000, Kosher, and Halal. Japanese matcha experts have praised their EU-standard matcha for its authentic flavor profile and consistent quality.
Complete Industry Integration
As a modern tea enterprise, Gui Tea integrates the entire value chain: cultivation, scientific research, production, global marketing, and tea tourism. Their 100,000-level aseptic workshop ensures microorganisms remain strictly controlled throughout the production process. The company offers comprehensive product lines including ceremonial matcha, organic matcha, culinary-grade matcha, flavored varieties, hojicha, premium green teas, and black teas.
With annual output valued between $10-50 million and a total factory area spanning 300,000 square meters, Gui Tea Group fulfills its mission of “sharing the cleanest tea with the world” while driving Guizhou’s tea industry onto the international stage.

Matcha produced by Gui Tea Group
Gui Tea Group produces ceremonial-grade matcha and culinary-grade matcha using advanced production techniques that combine traditional Japanese methods with modern technology. Their matcha production involves a meticulous 20+ step process that ensures exceptional quality and consistency.
Production Process and Quality
The company employs chagama (traditional iron kettle) style steaming techniques to preserve the vibrant green color and enhance the umami flavor of their matcha. Tea leaves are steamed for 15-20 seconds to achieve optimal enzyme inactivation, preventing oxidation and discoloration.
Gui Tea Group uses advanced ceramic ball mills to grind tencha (processed tea leaves) into fine matcha powder with a target particle size of 5-10 micrometers, ensuring smooth texture and optimal solubility. The grinding process is carefully controlled to maintain the delicate flavor profile.
Quality Standards and Certifications
All matcha is produced in a 100,000-level aseptic workshop, ensuring sterile conditions and minimizing microbial contamination. The company maintains strict quality control specifications, testing for 480 pesticide residues using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS).
Their matcha achieves a colorimeter score of >800, indicating high chlorophyll content and vibrant green color. The theanine content is maintained at ≥1.2%, contributing to the distinctive umami flavor and health benefits.
Product Innovation
Beyond traditional matcha powder, Gui Tea Group has developed over 30 matcha-based foods and beverages, including matcha chocolate and matcha ice cream, showcasing their commitment to product diversification and innovation in the global matcha market.
History of Gui Tea Group
Gui Tea Group emerged as a transformative force in the global matcha industry when it was established in Guizhou Province in April 2010 with a registered capital of RMB 190 million (approximately USD 27.5 million). The company rapidly evolved from a regional tea producer into a multifaceted modern tea enterprise that would challenge the traditional dominance of Japanese matcha producers.
The company’s infrastructure expansion has been remarkable, developing five state-of-the-art facilities spanning over 300,000 square meters, including four primary facilities and one refining facility. Gui Tea Group maintains control over 140,000 Chinese mu (9,333 hectares) of meticulously managed tea gardens, with 10,000 mu (666 hectares) proudly holding USDA and EC organic certifications.
The company’s commitment to quality is demonstrated through its comprehensive certification portfolio, including Halal, Kosher, AIB, FSSC 22000, HACCP, and Rainforest Alliance certifications. Their production process integrates traditional Japanese techniques like chagama (traditional iron kettle) style steaming with advanced Western technology, including ceramic ball mills that achieve a target particle size of 5-10 micrometers for optimal matcha texture.
Gui Tea Group’s Tongren factory represents a milestone in matcha production as the world’s largest single-site matcha factory, capable of producing 10 tonnes of matcha daily with an annual production capacity exceeding 4,000 tonnes. The facility operates under strict quality control standards, including a 100,000-level aseptic workshop environment and testing for 480 pesticide residues using advanced analytical techniques.
The company’s production methodology encompasses over 20 meticulous steps, from the initial 3-4 week shading process that reduces sunlight exposure by approximately 90% to enhance chlorophyll and L-theanine levels, through to the final packaging with nitrogen flushing to preserve quality. This comprehensive approach ensures their matcha achieves a colorimeter score of >800 and maintains a theanine content of ≥1.2%.

Why does Gui Tea Group test for exactly 480 pesticide residues in their matcha?
Gui Tea Group’s 480 pesticide residue testing reflects their commitment to meeting the strictest international food safety standards, particularly EU Regulation (EC) No 396/2005 concerning maximum residue levels in food and feed.
Using advanced gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) techniques, they test for this comprehensive range of potential contaminants. This extensive testing, combined with their USDA and EC organic certifications on 10,000 Chinese mu (666 hectares) of tea gardens, ensures their matcha meets global export requirements and exceeds safety standards in major markets.

Gui Tea Group uses a colorimeter to measure matcha color, targeting a score >800 which indicates exceptionally high chlorophyll content and vibrant green color. This scientific measurement ensures consistency across their massive production volumes.
Combined with their requirement for ≥1.2% theanine content, these precise specifications guarantee both the visual appeal and umami flavor profile that defines premium matcha. The high colorimeter score results from their 3-4 week shading process using black nets to reduce sunlight exposure by 90%, naturally boosting chlorophyll levels in the tea leaves.
