How long does it take for homemade wine to ferment? It depends on the fermentation temperature, the number of yeast needed for fermentation-the starting speed of fermentation and the amount of sugar added-because the sugar content of grapes is low, some of them are fermented with sugar. Generally, it takes 20-30 days, including post-fermentation time. When no gas is produced after brewing-fermentation is completed-skin residue can be taken out, filtered and bottled for preservation.

There are two points to pay attention to in brewing: first, hygiene-very important, mixed bacteria infection will make fermentation fail or wine quality worse; The second is the temperature -28-33 degrees. Excessive temperature will not only make the taste of wine worse, but also make miscellaneous bacteria susceptible to infection.
