Homemade wine is too sweet. If it is just beginning to ferment, you can add some fresh grapes. As long as we pay attention to hygiene, it will not affect the fermentation process, nor will it affect the quality of wine.

It is also possible that there is something wrong with your own fermentation. First of all, you should know the chemical changes that occur during fermentation. Sugar is polyhydroxy aldehyde or ketone, so sweetness means that the fermentation time is short, or the temperature is not enough and the enzyme activity is not high. It takes a long time to ferment if you want the taste of wine.
