#1 GLOBAL MATCHA PROVIDER

Japan produces 100,000 tons of tea every year, of which approximately 2,000 tons is Matcha. That makes Matcha the world’s most precious and unique tea, as it only represents 2% of the world’s annual tea harvest. Aiya’s average production per year reaches over 1000 tons, providing to over 50% of the market.

CONSISTENT QUALITY BY TEA SOMMELIERS

One of Aiya’s most important goals is to provide consistent quality not only throughout the year, but also every year. Matcha is always manufactured by blending from varieties of Tencha to maximize its quality. Taste, aroma, and color of Matcha are evaluated by tea sommeliers prior to grinding.

Currently, Aiya’s high quality is maintained by two in-house tea sommeliers. With more than 40 years of experience, the blend of Tencha is carefully evaluated and blended to ensure that consistent quality and grades are provided- regardless of the season.

ORGANIC CERTIFICATIONS

Aiya is the first company in the Matcha industry to carry organic certifications for all international markets. USDA, QAI, OMIC, and JAS certify all organic products for the North America, European, and Japanese markets, respectively. Ensuring global organic recognition, Aiya’s clients are able to sell their wares as certified organic throughout the world.

GLOBAL SUPPORT SERVICES

Aiya offers resource offices throughout the world to support its international clientele. Run by affiliates owned by the parent company, these offices are the point of contact for orders, questions, support, import, and other tea-related solutions.

Our international offices are located in Europe (Hamburg), The United States (Los Angeles), China (Shanghai) and Japan headquarters (Nishio).

MANUFACTURING SCALE

Aiya’s large-scale procurement process ensures consistency and quality. Because Aiya owns over 80% of the harvesting rights to the Nishio tea plantations, it can blend its teas so the final product always conforms to its strict specifications of this high-quality tea. Smaller manufacturers with limited procurement options may be subject to great fluctuations in quality: for example, one abnormal rainstorm could easily ruin the entire annual harvest.
