Wine fermented into alcohol by yeast with the sugar of fruit itself contains the taste of fruit and alcohol. Therefore, folk families often brew some fruit wine to drink. Such as plum wine, wine, bayberry wine, kiwi wine, etc. Because there are some wild yeast and some sucrose in the peel of these fruits, some fermentation can be carried out without adding extra yeast, but the traditional folk brewing methods are often time-consuming and easy to be polluted. Therefore, adding some active yeast is an ideal method to brew fruit wine quickly.
