Black teas are known as fully oxidized or fermented teas. Their black like color is the result of being exposed to oxygen before being dried. When we think of an old fashioned British cuppa, we think black tea. The best of these are known for their rich malty depths, balanced astringency, brisk character and coppery color. They take milk and sugar well and are traditionally enjoyed in the morning. Black teas are known to have moderate antioxidant levels, and typically have more caffeine than other tea varieties.
