In Taiwan's Nantou county, in the Central Mountain Region, growers cultivate an oolong known locally as Formosa Jade Oolong, sometimes called Jade Dragon Tea, named for the pale green cast the leaves take on after processing. The region's climate and soil are well suited to this particular variety, and the colour itself carries weight in Chinese culture, where jade has long stood for nobility, beauty, purity, and grace.
The leaves are picked by hand, taking only the most tender buds, then dried in the sun before processing begins. Partial oxidation is what gives the tea its jade green hue, a step that takes a practiced hand and real patience to get right. Once oxidation reaches the point the maker is after, the leaves are rolled tight to concentrate their flavour, then pan-fired at high heat to stop the oxidation in its tracks and fix the colour and taste.
The cup itself is thick-bodied, with a tangy, layered aroma and a spiced character running underneath. Caffeine sits in the moderate range, roughly 20 to 40 mg per cup, so it's gentler than a strong black tea without being negligible. It holds up well served cold as well as hot, which makes it a flexible tea to keep on hand.
To brew it, let boiled water cool to around 80°C, then steep for about three minutes, adjusting the time to taste. The leaves are good for more than one infusion, and each subsequent steep tends to shift slightly, drawing out different notes and nuances as the leaves continue to open. Some drinkers enjoy tracking how the character develops from one steep to the next rather than treating the first cup as the whole story.
This oolong is also valued for its antioxidant content, and it has traditionally been drunk to support digestion, ease stress, and sharpen focus, though those are traditional uses rather than confirmed medical benefits.
