If you read our tasting notes you may be a bit apprehensive about trying this tea because it is so 'out there' but we HIGHLY recommend that you give this 'dank' looking oolong a try. 

GABA tea: GABA stands for gamma-amino butyric acid, an amino acid that is one of the main neurotransmitters in your central nervous system. Neurotransmitters help nerve signals to travel between cells (neurons). GABA tea has an abundant amount of health benefits. Some would even describe GABA as a ‘super tea’. 

Onyx GABA is a dark roasted Taiwanese oolong derived from the Fo Shou cultivar. This cultivar has some wild and unusual flavours and is and incredibly similar to filtered coffee.  Onyx GABA is laboratory tested and contains about 200mg of GABA which is 35 times the amount found in normal tea. The farmers achieve this by alternating the leaves between air and a nitrogen rich environment (with no air) during the oxidation phase. This tea is very refreshing and uplifting. with a gentle buzzy stimulation and cooling perspiration.
