Large tightly rolled leaves with fresh green and darker tones, giving sweet orchid-like aromas. The tea soup, pale orange in colour, has a smooth taste, creamy mouthfeel, and rich raisin notes, a pleasant sourness with a fruity fragrance providing a high concentration of GABA. Overall, a good depth and lasting flavour.
This tea garden is located within the Alishan mountain range, one of the famous tea mountains of Taiwan, bordering the Chiayi and Nantou Counties among others. Organically grown at an elevation of 1300m, this tea has been hand picked & harvested in Winter '20 using the Jinxuan cultivar. This cultivar is normally used to produce Milk Oolong. After picking the leaves then undergo GABA Oxygen Free fermentation processing. Producing a very small batch, high quality tea.
GABA (Gamma aminobutyric acid) is an amino acid found within the human brain aiding efficient neuron communication. The same amino acid is naturally found within the tea plant. In 1984, Dr. Tsushida Tojiro's team at the National Institute of Vegetables and Tea Science, Japan, developed a new technology in order to boost the natural levels of GABA through an Oxygen Free (Anaerobic) Fermentation Process, whereby the unfinished tea is placed in a nitrogen filled drum that displaces oxygen. Introducing the tea to this process after six to ten hours resulted in the conversion of glutmatic acid in the tea to GABA without interrupting caffeine or catechin content, leaving the leaves enriched with large amounts of GABA.
Since the introduction of GABA enriched teas in the late 1980's, the popularity and its production has been particularly embraced in Japan & Taiwan. Further research found that GABA rich tea is beneficial for people with hypertension, the tea's overall calming effects and also, its ability to aid the reduction of blood pressure.
