  • From Taiwan
  • Si Ji Chuan variety (4 seasons)
  • 400-600m altitude
  • Natural farming
  • spring harvest

GABA in tea was discovered in the 1980s by a Japanese researcher at Japan's National Research Institute of Tea. When looking at how to preserve food, he discovered that if you expose tea to nitrogen during the oxidation process, the content of GABA goes up.

According to the Japanese government, the content of GABA should be at least 150mg/100gr of tea. This GABA contains more than 200mg/100gr of tea.

How is it made:


  • Approximately 2 weeks before picking, the plants are shaded, glutamic acid is produced as a result.
  • The leaf is picked and goes into a sealed vessel that is vacuum drawn to remove the oxygen.
  • Nitrogen is then put into this vessel for about 6 to 10 hours. The glutamic acid now turns into GABA (Gamma-AminoButyric Acid).
  • After this, the leaf is heated in the wok to stop the oxidation.
  • After this, the oolong is processed as normal, rolling, drying, compressing.
  • At last, the tea is baked to further dry
