Homemade wine needs to be fermented no more than 10 days before the skins can be filtered.

Primary fermentation is generally no more than 10 days, if the time is too long easy to turn into vinegar, generally the grape skins are fully discolored, and there is a tendency to sink for the best time, after the opening of the seal, fish out the grape skins floating above, filter out the bottom of the barrel of the grape seeds and too much wine mud. The cloudy wine was then re-barrelized and entered into secondary fermentation.

Secondary fermentation and aging does not require too much human intervention, carried out in a sealed environment, to prevent the entry of oxygen, to be placed in the fermentation bucket in a cool, low-temperature place, but if the filtering of skins and seeds of the wine is still intense gas production, you need to continue to use a plastic cloth to tie the mouth of the mouth lightly, to be two days after the no longer intense gas production, that is, the mouth of the seal with a tightly tied plastic cloth.

Extended information:

Homemade wine fermentation apparatus should be cleaned and sterilized with hot water or a high degree of alcohol and drained before use. 25℃, avoid higher than 30℃. Because of the wide variety of microorganisms on the skin of the grapes, it is recommended to add an appropriate amount of active dry yeast before fermentation to inhibit the propagation of stray bacteria.

It is strictly forbidden to add water to the fermentation vessel during the fermentation period. If foreign matter such as white hairs and mold spots appear during fermentation or storage, it means that it is infected with stray bacteria, so please do not drink it anymore.

Subject to sterilization conditions, there may be other microorganisms in the wine after fermentation of home-brewed wines, which may easily lead to the deterioration of the wines. Therefore, it is recommended that home-brewed wines be stored in a dark, cool environment with a stable storage temperature between 10-15℃. Don't use non-food-grade plastic bottles to store your wine, and it's recommended that you drink it all within a short period of time, rather than storing it for a long period of time.
