What is oolong tea, exactly?
Like green tea, oolong tea (or wulong tea) comes from Camellia Sinensis leaves. Unlike green tea, which isn’t oxidized at all, oolong tea is partially oxidized. It receives anywhere between 10% and 80% oxidation. Because it can be oxidized so much or so little, oolong tea is a universe unto itself. You may find that one variety of oolong tea has an amber appearance very similar to black teas, while another is golden green, practically indistinguishable from green tea infusions. The range of flavours fluctuates just as widely, from deep, rich oolongs to sweet, floral brews.
