The word "chai" is the word for tea in many parts of the world. It is a centuries-old beverage whose origins are said to go back over 5,000 year to India, where it then spread to Asia and the Middle East. Chai is black tea brewed with select spices, sweetener, and milk. The spices used vary from region to region, but the most common are cinnamon, cardamom, cloves, ginger, and pepper. Chai that is found in tea bags or loose leaf form is usually unsweetened and contains no milk.
