Description
Health-oriented tea KOHEI is an organic green tea grown and processed by Takahashi san in Oita to increase its levels of GABA (gamma-aminobutyric acid), a natural component of green tea.
 
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).
 
Grown by the producer of our super popular KOJI and KOTARO tamaryokucha, KOHEI greets you with a delicious gingerbread aroma when you first open its bag. Its beautiful pale golden liquor is sweet, refreshing, easy to drink, with hints of cinnamon and citrus notes and leaves a pleasant bitterness on the tongue. Its positive impact on sleep disorders and low levels of caffeine make it a great late afternoon or early evening tea.
 
Our team fell in love with the cute design of KOHEI’s original bag made by Takahashi san and decided to keep it as it is. The drawing represents Takahashi san and his mother who leads family business alongside him, and was based on this photography (see below).
 
KOHEI is sold in 50g bags and is also available in bulk (5 x 50g with a 15% discount).

Tasting Notes

sweetness

A sweet-tasting tea is a very light tea that leaves a sensation of natural sweetness in the mouth.

UMAMI

Although there is no official translation of the word “umami”, some call it “savory taste”: it leaves a mild and lasting pleasant brothy after taste and is recognized as one of the five basic tastes (together with sweetness, sourness, bitterness, and saltiness). It also induces salivation and a furriness sensation on the tongue, stimulating the throat, the roof and the back of the mouth.

BITTERNESS

The natural bitterness of green tea comes from the way it is made. Unlike black and oolong teas, green teas are made from the unfermented leaves of the tea plant, which keeps the antioxidants intact, but also gives them the bitter taste. This bitterness can be regulated with the water temperature : the higher the more bitter and vice-versa.

CAFFEINE

Caffeine is a naturally-occurring stimulant, found in several plants. Caffeine is water soluble, and is extracted into the brewed cup when preparing tea. In most cases, tea has much less caffeine than coffee.

CATECHINS

Catechins are a type of polyphenol (EGCG) and are the main astringency component in green tea, long known as tannins. In order to release more catechins you will need higher brewing temperature at around 80 but this will also increase the astringency and bitterness of your tea because of the caffeine. Dont use such temperatures for Gyokuro.

THEANINE

L-theanine (here referred to as theanine) is an amino acid that has a relaxing, but not sedating, effect. It is renowned for its ability to put you in the ideal state of calm attentiveness. It can sharpen focus, while reducing stress and enhancing overall well-being. Theanine can interact with caffeine, allowing a smaller dose of caffeine to have a stronger effect in terms of boosting concentration and alertness.

FRAGRANCE

The fragrance of a cup of green tea can vary from a highly roasted aroma to a fresh one.

Producer

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.
