How Is Oolong Tea Made?
Both green and dark oolongs are created from the leaves of the Camellia sinensis plant. Green oolongs tend to be plucked at high altitudes from April through to autumn, whereas more mature leaves are chosen for dark oolongs, with harvesting taking place from late spring.
Production is a complex process involving several steps, from withering to firing – but perhaps the most unique stage of all is the laborious hand rolling, which is what gives green oolongs their distinctive bead shape, and dark oolongs their long, curled shape.
Oolong Tea and Caffeine
Oolong and green tea contain around 31mg of caffeine per 100ml, which is a little less than black tea and a little more than white and yellow tea. (It’s a good idea to bear in mind that this figure can vary depending on the specific batch of tea you drink, and the time, temperature and strength of your brew.)
