When I and my family were visiting Koh Chang in Thailand we lived close to a newly opened restaurant in White Sand Beach - Padamas. They served this tea called Oolong. Even though I drink a lot of tea and mostly green tea I've never tasted Oolong tea before. It has a sweet and lovely taste. The difference between green, oolong and black tea is that for oolong the oxidation is somewhere between the both others. First I got told to let the leaves stay in the pot but I found the tea to be better if you let them stay in the pot for 2 - 4 minutes and then you take them out. You can reused them multiple times. I'v heard that the chinese say the third time is the best, I don't know but it is probably true. :)
