Oolong tea or Chinese "black dragon", this kind of tea, when the sheet is oxidized, darkened, turned brown and the middle left of green tea has become a "semi-fermented". This is a delicate tea fermentation degree, it is "green". Lovely delicate flavor, in the presence of a delicate astringency. I prefer the natural flavor of oolong tea, of course, in China and Taiwan oolong flavored, but the natural aroma of the brew oolong can feel myself a mug, by the way oolong tea can brew up to 7 or more times, each time the tea will change its taste. This tea is brewed me 4 or 5 times. Excellent extractivity, this gives both invigorating and calming effect.
