Black teas are often considered to be a dense tea in relation to green and white teas, creating a more potent flavor. They are known to help maintain heart health and improve skin and bone strength.
Because of the higher caffeine content, black teas are best for when you are in need of an energy boost. Black teas hold approximately 20% of the caffeine in one cup of coffee, making them more highly caffeinated than white and green teas. That is why you will find some black teas that say they are decaffeinated.
