Earl Grey is traditionally made from a blend of Chinese and Indian black teas, flavored with oil from the citrus bergamot fruit. 

Legend has it that the Earl of Grey was on a Diplomatic trip to China when he saved the life of a local Mandarin. As a gift of gratitude, the Diplomat was given the recipe for creating this tea, which he brought back with him to Britain to share what would go on to become one of the most popular English tea blends.
