Efforts to Keep Tea Leaves in Good Condition:
We make continuous efforts at every single step from harvest of tea leaves to delivery to our customers. This encompasses the harvest, finishing process, storage at the factory, delivery, and ends with our customers all over the world being able to enjoy a farm-fresh cup of Japanese green tea.

"Aracha" tea leaves, just after harvest and processing by farmers, are brought to the factory. "Aracha" tea leaves are finished: sorted, dried, blended, and on so on. Then they are vacuum packed in 20kg (44.1lb) bags, and stored in a special cold storage chamber. Temperature in the cold storage chamber is kept at about 0C (32F) to 5C (41F) throughout the year.
The finished tea leaves are repackaged into smaller size bags just before shipment to our customers around the world. The remaining tea leaves are vacuum packed and stored in the cold storage chamber again. The smaller size bags are packaged with nitrogen in order to keep the tea in good condition even during international delivery.
The harvest season is the busiest time of year not only for farmers but also for the factory. All "Aracha" tea leaves can't be finished at one time. In fact, more than half of the unfinished "Aracha" tea leaves are vacuum packed and stored in the cold storage chamber until after the busy harvest season is over. The average tea factory handles ten to several hundred tons (1000 kilo grams) of tea leaves per year.

In the case of Matcha, tea leaves are stored in a cold storage chamber as "Tencha" tea leaves before being ground into the fine powder known as Matcha. Tencha is ground into Matcha just before shipment to the customer. If the finely powdered Matcha was stored for a longer time, it would more easily deteriorate.
As above, it is most important to vacuum pack or nitrogen pack the tea leaves at every single step just after "Aracha" tea leaves are brought into the factory, in order to keep the tea in ideal condition throughout the year. These processes protect the tea leaves from oxygen, heat, moisture, and light, and require a surprising amount of time and effort.

Analysis of Tea Leaves:
We periodically ask a third party laboratory to analyze our teas for residual pesticides, heavy metals, radiation, and so on, to ensure safety. Attached are images of the analysis report on this year's crops. No suspicious analytes were detected.

As above, our teas are continuously and strictly inspected. We strongly believe that ensuring the absolute safety of our products is most important. It is our sincere wish that our customers enjoy our teas at ease, with the knowledge that they can depend on us to provide them with a safe and wholesome product.

Shincha (the first tea of the year) is harvested starting at the beginning of May in Kyoto. We are planning to sell some limited edition Shincha items only available this Shincha harvest season. Celebrate our first tea harvest of the year with Hibiki-an's Shincha and enjoy the remarkable fresh flavor, which can only be experienced once every year! Please wait and see!
