Description

Health-oriented tea KOKI is an organic Japanese black tea grown and processed by Takahashi san in Oita to increase its levels of GABA (gamma-aminobutyric acid), a natural component of tea.

GABA-rich koucha KOKI is a naturally sweet koucha that can be enjoyed even in the evening.

GABA is an inhibitory neurotransmitter also found in human bodies. Its main role is to reduce neuronal excitability. Research has shown that GABA contributes to preventing high blood pressure, helps with sleep disorders, and reduces stress and anxiety.

Thanks to the combination of GABA with other healthy nutrients specific to tea such as l-theanine and other polyphenols, GABA-rich tea has a deeper impact than regular green tea on chronic stress-induced autonomic imbalance, and related risks for cardiovascular disease (see examples of recent studies published here, here and here).

Producer Information

TAKAHASHI YUZO

Established in 1963, the Takahashi green tea factory is located in Usuki (Oita pref., Eastern Kyushu) and produces organic green tea since 2001. It was the first green tea farm in Oita to receive the organic JAS certification in 2001.

Takahashi san is now the second generation of his family to lead his business and is specialized in tamaryokucha, a green tea known for its jade color (tama), quite similar to sencha, but whose leaves have a curly shape, and not needle-like. The very last stage of the processing method is different: the tea leaves are put inside drums and dried with hot air.

Takahashi san grows seven different tea cultivars, mainly Yabukita.
