In the process of liquor cellar storage, the following three changes have taken place by absorbing the essence of the sun and the moon and the aura of the earth through the container at a suitable temperature (metal and glass containers can not be used for cellar storage, and the traditional coarse-glazed wine cellar is used):

1, volatile

In the long fermentation process, fusel oil and sulfide substances contained in liquor naturally volatilize, which greatly reduces the irritation of liquor and harmful substances in liquor. Of course, it is impossible to completely reduce them.

Step 2 unite

Fermentation is a long process, and the activity of ethanol molecules will decrease with time, so the taste of liquor after cellar storage will become soft.

3. Chemical changes

Some molecules in liquor are unstable. In the process of cellar storage, some chemical reactions will occur due to moderate temperature and environment, resulting in new esters (from alcohol to fat). Esters are the main source of liquor aroma, so cellar storage liquor will be more fragrant. This kind of cellar storage technology is also known as impurity removal and fragrance enhancement.

18 meter underground wine cellar environment can be said to be very good, with constant temperature and humidity all year round, which is a good wine storage environment. In this environment, the quality of health wine cellar is a good product.
