Niu Lan Shan Zhen Pin 20-Year comes from the century-old Niu Lan Shan brand and is made with selected sorghum and wheat, using water from the Chaobai River. Following the traditional Er Guo Tou method that retains only the most refined middle portion, it undergoes grain-based solid fermentation and an extended 20-year resting period, resulting in a mellow, layered profile that reflects the depth and heritage of classic Beijing craftsmanship.
