The autumn wine making season has come, but if we don't even know the factors that affect the wine production, how can we use the wine making equipment to make wine? What other factors affect the production of Baijiu besides the coolness and airtightness of brewery and winery? There are many factors that affect wine production, such as cooling and sealing of equipment in small breweries, starch concentration, fermentation temperature and sanitary conditions.

白酒发酵是淀粉经糖化转化为糖，然后糖转化为乙醇的过程。因此，淀粉含量直接影响着出酒率，这也是不同谷物酿酒设备出酒率不同的原因。当我们选择谷物时，我们需要选择新鲜、饱满、无霉、无杂质和高淀粉含量的。

Baijiu fermentation is the process of amylose conversion to sugar and then sugar to ethanol. Therefore, the starch content directly affects the liquor yield, which is also the reason for the different liquor yield of different grain brewing equipment. When we choose grain, we need to choose fresh, full, mildew free, impurity free and high starch content.

酒曲，一种酿酒的发酵剂，在有氧条件下大量繁殖，产生更多的酵母，将淀粉转化为糖，并在无氧条件下将糖转化为乙醇。因此，酿酒设备发酵时，糖化前期需要少量氧气，需要半封闭发酵；在后期，需要厌氧发酵，这需要完全密封发酵。在这个过程中，空气接触过少或过多都会影响酒的产量。

Distiller's yeast, a kind of starter for liquor making, propagates in large numbers under aerobic conditions, produces more yeast, converts starch into sugar, and converts sugar into ethanol under anaerobic conditions. Therefore, a small amount of oxygen is needed in the early stage of saccharification and semi closed fermentation is needed; In the later stage, anaerobic fermentation is needed, which requires complete sealed fermentation. In this process, too little or too much air contact will affect the yield of wine.

如果环境温度过高或过低，将影响酿酒设备的发酵。如果温度低于15℃，该菌株将不具有活性，发酵将不可能进行。如果温度高于36℃，有益菌不能存活或杂菌繁殖快，导致出酒率低。一般来说，发酵的适宜温度为20-30℃。夏季酿酒可以降低曲温，并在发酵过程中采取相应的降温措施；冬季，酒曲温度稍高，在发酵过程中采取加温和保温措施。

If the ambient temperature is too high or too low, the fermentation of brewing equipment will be affected. If the temperature is lower than 15 ℃, the strain will not be active and the fermentation will not be possible. If the temperature is higher than 36 ℃, the beneficial bacteria can't survive or the miscellaneous bacteria multiply quickly, which leads to the low liquor yield. Generally speaking, the suitable temperature for fermentation is 20-30 ℃. In summer, koji temperature can be reduced and corresponding cooling measures should be taken during fermentation; In winter, the temperature of distiller's yeast was a little higher, and heating and heat preservation measures were taken in the fermentation process.

酿酒设备和发酵容器、发酵水、冷却床、操作工具等要进行。建议使用5‰的高锰酸钾或生石灰。

Wine making equipment and fermentation containers, fermentation water, cooling bed, operating tools, etc. should be disinfected. It is suggested to use 5 ‰ potassium permanganate or quicklime for disinfection.

虽然我们说一罐酒醅发酵后多少酒是固定的，但设备选择不当也会影响酒的产量。如果酿酒设备的冷却和密封性能不好，在蒸的过程中会有大量的酒挥发，这会降低酒的产量。设备设计不合理，蒸酒过程中透气性差，酒不能完全挤出。因此，酿酒时选择一套合适的工具对我们来说非常重要。

Although we say that how much wine is fixed after a can of fermented grains is fermented, improper selection of equipment will also affect the production of wine. If the cooling and sealing performance of wine making equipment is not good, there will be a lot of wine volatilization in the process of steaming, which will reduce the output of wine. The equipment design is unreasonable, the air permeability is poor in the process of steaming, and the wine can not be completely extruded. Therefore, it is very important for us to choose a suitable set of tools when making wine.
