GABA Oolong is somewhat of recent innovation having been discovered/developed by the Japanese in the late 1980's. GABA, or gamma-aminobutyric acid is a compound naturally produced in the human brain and is thought to decrease stress and anxiety. Many products in Japan, and increasingly in Taiwan and other Asian countries are now GABA enriched as it becomes more popular. GABA oolong is produced much the same as normal oolong (camellia sinensis, i.e. tea, naturally contains GABA) but with an added processing step in a nitrogen rich container, resulting in a much higher amount of GABA than normally present in tea and a distinctive aroma. Our GABA oolong is produced in Taiwan and has a unique taste and aroma, having an orange-brown infusion, full mouth feel, light caramel notes and a touch of sweetness on the tip of the tongue.
