This GABA oolong is semi-oxidized tea from City Kuoshing (Guoxing), Nantou county, Taiwan and grows along Wu river.

GABA tea contains a high percentage of Gamma-Aminobutyric Acid, which effects on the nervous system.

About two weeks prior to plucking, GABA oolong leaves are partially shaded, which causes increased production of glutamic acid.

During the oxidation-phase of production, all oxygen is replaced with nitrogen gas, whose presence causes the glutamic acid to be converted to Gamma-Aminobutyric Acid.

More information about GABA tea you can find here.

Leaves: Leaves are greyish-green, rolled into small balls.


Very soft taste with deep fruitiness and cinnamon notes.


Warm up the tea pot with the boiling water, put 2-5 grams of tea, and pour small amount of the boiling water into the tea and pour out, then pour 225-250 ml of boiling water and cover tea pot for three minutes before serving.

Boiling temperature - 95°C (205°F).

You can use this amount of tea 8 to 10 times.

The tea leaves come unrolled for full flavor.

Additional information

This is one of the traditional ways of brewing. Depending on individual gustatory preferences you can vary brewing time from 35s to 5 minutes.

You can also use Chinese traditional way of brewing - spilling, using Gaiwan and brew for 3-5 second each time.

Please note, that it is natural tea with high content of active elements, including caffeine, and minerals and some unusual feelings could appear. In that case we recommend decrease quantity of dry leaves and brewing time.

What a lovely oolong. It’s fragrant, fresh and a little bit sweet (a tiny hint of caramel). It holds up very well in multiple steeps. I haven’t noticed any effects from the GABA specifically, but that might be because I only drink it on occasion instead of daily.

This tea is exceptional. Even with multiple steeps this tea is not bitter in any away and the tea develops a mild sweet flavor around the fourth and fifth steeps. I will be purchasing this tea again on my next order.
