Oolong teas undergo a longer and more intricate production process than other tea types, requiring careful attention at every stage to develop their depth and character. This Gaba Oolong is made from the Tagda 78 cultivar and follows a heavily oxidized oolong style.
Hand-plucked leaves are withered until they lose about 30–35% of their moisture, followed by an initial fermentation of 10–12 hours. The leaves are then placed in a setting machine to promote further oxidation for several hours.
The next day, the leaves undergo a second fermentation of 10–12 hours. Once the desired aroma and flavor profile develop, they are transferred to a fixing machine, similar to the enzyming step used in green tea production. Fixing is done at temperatures above 300°C for 10–15 minutes to halt oxidation.
After fixing, the leaves are lightly rolled for a few minutes, shaped into pearls, then dried for approximately 20 hours before sorting and packaging.
