Summer in Japan is really hot. In addition to that, very very damp, which makes the situation worse.
In order to overcome scorching heat, we have a summer tea known as "Mugicha". Strictly speaking, this is not a tea-tea because it's made from roasted barley. Usually, I insist that tea has to be made from camellia sinensis, but this is an exception. I can accept mugicha because it helps us a lot.
It is caffeine-free so that men and women of all ages can gulp the tea. Truly, it is a must for Japanese summer.
