Despite being referred to as a 'tea', mugicha does not contain any tea leaves. It is instead an infusion of roasted barley that is normally drunk cold in Japan during the warmer summer months, making it a healthier alternative to refreshing soft drinks and other sugary beverages. Take a look at japancentre.com's Tea section for a wide range of teas that can be enjoyed hot or cold.
This is a great quality tea which I brew with hot water and drink after it has cooled. It has a pleasant, roasted flavour and I would definitely recommend it.
