All kinds of tea we have roast, from green tea to oolong tea to black tea. The purpose of roasting can not only reducing moisture for longer preservation but also can make the tea has its own personality and taste sweeter without adding anything inside.

By controlling the time and temparature, we can create different flavor, such as sweetness and aftertaste level, especially for oolong tea. A little change in time or temparature can make a huge different for the taste.
