It is recorded that Princess Wencheng married to Tu Bo in the 7th century and brought the advanced brewing methods into Tibet. After 1300 years, Tibetan wine culture which base on barley wine is famous in the world for its unique charm.
First, wash up the barleys, but don't let them in water for a long time. Then, put them into pot, with some water which is the two-thirds of barley to cook. When the water is completed absorbed by barley, use a stick to stir the barley to make them cooked completely. When the barley is about 80 percent done, lift down the pot to cool the barley for 20-30 minutes, to let barley absorb the water in the pot. When barley is still warm, lay it on the prepared clean cloth; and then sprinkle some thing in it to ferment. After done, put the barley into pot, and package it with quilt or some other things to keep warm. In summer, it only needs two days to ferment, while in winter, it will ferment after three days. If temperature is suitable, the wine fragrance will come out after one night. Then, put barley into the pottery container to filter barley wine.
