The older, the wiser. The longer the Baijiu is, the better the taste is. Baijiu distilled liquor has a pungent irritation, a bad smell, a bitter taste and a coarse flavor. It is called new wine. When Baijiu is properly stored, the aroma will increase, the wine will be soft, and the components in the wine will be more harmonious. The storage of liquor should not only take into consideration the time factor, but also consider the temperature, humidity, ventilation, light and storage capacity, and different storage containers and capacity. It is better to use ceramic cylinder to store Baijiu, and the storage temperature is 20 degrees.

贮存时间与酒质的变化

Changes of storage time and liquor quality

在酒类生产中，不论是酿造酒还是蒸馏酒，都把发酵过程结束、微生物作用基本消失以后的阶段叫做老熟。老熟有个前提，就是在生产上必须把酒做好，次酒即使经长期贮存，也不会变好。

In the production of liquor, whether it is brewed liquor or distilled liquor, the stage after the end of fermentation process and the disappearance of microbial action is called aging. There is a premise for aging, that is, the wine must be made well in production, and the second wine will not get better even after long-term storage.

对于陈酿也应有个限度，并不是所有的酒都是越陈越好。酒型不同，以及不同的容器、容量、室温，酒的贮存期也应有所不同，而不能孤立地以时间为标准。夏季酒库温度高，冬季温度低，酒的老熟速度有着极大差别。应该在保证质量的前提下，确定合理的贮存期。

There should also be a limit to aging. Not all wines are as old as possible. The storage period of wine should be different with different types of wine, different containers, different capacities and different room temperature, and the time should not be taken as the standard in isolation. In summer, the temperature of wine storehouse is high, and in winter, the temperature is low. Reasonable storage period should be determined on the premise of quality assurance.

清香型和浓香型白酒，在贮存初期，新酒味突出，具有明显的糙辣等不愉快感。但贮存5-6个后，其风味逐渐转变。贮存1年左右，已经为理想。而酱香型白酒，贮存期需在9个月以上才稍有老酒风味，说明酱香型白酒的贮存期应比其他香型白酒长，通常要求在3年以上较好。酱香型酒入库时的酒精浓度高，大多在55度左右，化学反应缓慢，需要贮存时间长。

In the early storage stage, the new flavor of Baijiu and Luzhou flavor liquor is prominent, and it has obvious spicy and spicy taste. However, after storage for 5-6 months, the flavor gradually changed. It is ideal to store it for about one year. Baijiu Baijiu Baijiu liquor has a storage period of more than 9 months and only a little old wine flavor. It indicates that the storage period of Maotai flavor liquor should be longer than that of other aromatic liquor, and usually requires more than 3 years. The alcohol concentration of Maotai flavor liquor is high when it is put into storage, most of which are about 55 degrees. The chemical reaction is slow and the storage time is long.
