The yield of traditional brewing is low. However, the new technology and equipment for high-yield brewing with raw materials can increase the liquor yield by about 70%. According to the grain yield of 45-degree liquor 100 kg, the rice wine yield reached 100%, corn 83%, sorghum 85% and wheat 78%. For example, 100 kg of rice can produce 300 kg of rural low-alcohol rice wine, or 100 kg of 45 ~ 50% liquor.
