Earl Grey is a black tea blend flavored with bergamot oil, which gives it a distinctive citrusy aroma and flavor. It is named after Charles Grey, 2nd Earl Grey, who was the British Prime Minister in the early 19th century. Legend has it that the tea was specially blended for him by a tea trader as a thank-you for helping to resolve a diplomatic crisis. Today, Earl Grey is one of the most popular tea blends in the world and can be enjoyed both hot or iced, with or without milk and sugar.
