Method for blending apple wine by fermenting concentrated apple juice

A method for blending apple wine by fermenting concentrated apple juice comprises the following steps: adding potassium metabisulfite into clean apple juice; standing for one time and then adding an activated active dry yeast; fermenting at a temperature of 15 DEG C to 25 DEG C until the sugar degree is not changed, so as to obtain wine liquid; filtering the wine liquid with diatomite; after ageing, filtering with a filter membrane to obtain raw apple wine; uniformly mixing the raw apple wine, water and the concentrated apple juice to obtain material liquid A; adjusting the acidity to be 0.2 percent to 0.6 percent to obtain material liquid B; after filtering the material liquid B, carbonating to obtain the apple wine. The concentrated apple juice is used as the raw material; compared with a traditional fresh fruit fermentation process, a production period of the method is not limited by seasons, and the raw material concentrated apple juice is more easily preserved and transported.
