Taiwanese Oolong Tea
Oolong tea is one of the six best kinds of Chinese tea. Oolong tea is a half-fermented tea because it is not fermented all the way to the production. It is categorized between non-fermented green tea and full-fermented black tea. The rate of fermentation is not necessarily 50% but it ranges from 15% to 80%. So there are many kinds of oolong tea as far as its taste goes: some tastes like green tea; others like black tea.
