DIFFERENCE BETWEEN GREEN, OOLONG AND BLACK TEA

Tea leaves are crushed and dried to extract oils from them, after that they are exposed to open air depending on what kind of tea is being produced. The more they are exposed to air the more amount of caffeine they have. This whole process is called fermentation that is responsible for changing the color of tea and affecting the flavor.
