In Japan, kukicha has been stigmatized as a poor man's drink, because, like brown rice, it brings back memories of the days of deprivation during and after World War II. Since it contains only one-tenth the caffeine of sencha and because it is the most alkalinizing Japanese tea, it is considered to be the most balanced beverage. Twigs are steamed, dried, and stored in paper bags for two to three years in order to develop the best flavor.
