Sweet fermented grains and fermented glutinous rice share the same recipe and the only difference is that the sweet fermented grains in Qinghai use highland barley as the main ingredient instead of glutinous rice.
Highland barley is a unique crop on the Qinghai-Tibet Plateau which has a long growing period because of the many hours of sunlight in that region. Sweet fermented grains taste light and cool in summer while it can warm your stomach in winter.
