GABA Japanese Green (Organic)

Our Organic GABA (Gamma-aminobutyric acid) Green Tea is made using organic shade-grown raw leaves grown for sencha. Tea leaves with even higher levels of GABA values are created by using shade-grown raw leaves that are high in amino acids and repeating anaerobic and aerobic treatments three times. Our Organic GABA Green Tea contains over 300 mg of GABA/100g of tea which is higher than other GABA green teas.  As with all GABA tea, this tea undergoes a period of processing in an oxygen deprived environment (in this case around 8 hours). Typically, this involves placing the tea leaves in a special vacuum tank that is then flushed with nitrogen. The leaves undergo a very light but very slow oxidation that vastly increases the GABA content.

Even though the GABA tea processing was invented by Japanese scientists, it was Taiwanese tea growers who really popularized it. While GABA Oolong from Taiwan is the most popular and common type at the moment, some GABA Green tea is also produced in Taiwan. Japan is also producing GABA green tea, but the production is limited and most of this tea stays in Japan.
