Genmaicha is the Japanese name for green tea combined with roasted brown rice. It is sometimes referred to colloquially as "popcorn tea" because a few grains of the rice pop during the roasting process and resemble popcorn. This type of tea was originally drunk by poor Japanese, as the rice served as a filler and reduced the price of the tea; which is why it is also known as the "people's tea". Today it is consumed by all segments of society.
