Black tea is the most common type of tea accounting for up to 85% of total tea consumption in the western world. Black tea is fully oxidized and has a darker appearance, stronger flavour, and higher caffeine content compared to other teas. The caffeine content in black tea is still around half the level of coffee. Black teas are processed in either of two ways, CTC (crush, tear, curl) or orthodox. Often black teas can be consumed with sugar, milk, or lemon and offer some of the same health benefits as other teas.
