Genmaicha (玄米茶) is a type of Japanese tea made by mixing sencha or bancha with toasted rice. Though there are different types, 1:1 ratio of toasted rice and bancha is regarded as the standard genmaicha. Because the tea leaf used is half the amount of usual tea, genmaicha contains less caffeine compared to sencha or other green tea. It is also known as "brown rice tea" or "popcorn tea" due to the inclusion of popped rice kernels. Common variations include mixing in matcha and mixing in other ingredients such as black soybeans.
