Method for multi-strain compound fermentation of honey vinegar

The invention provides a method for multi-strain compound fermentation of honey vinegar, which comprises the following steps: firstly, activating acetobacter aceti, gluconacetobacter hansenii and foal bacillus, preparing a seed culture solution, preparing sterilized honey water, inoculating 5-12% of the seed culture solution, and fermenting to obtain honey vinegar fermentation liquor; and finally, transferring the honey vinegar fermentation liquor into an aging tank for aging to obtain the honey vinegar. According to the brewing method of the honey vinegar, the total acid content of the prepared honey vinegar exceeds 40 g/L and the non-volatile acid content is 8.5-13 g/L by effectively compounding the fermentation strains and controlling the fermentation process, the content of the non-volatile acid in the honey vinegar can be increased, the honey vinegar is softer in taste and full in acid feeling, the honey vinegar prepared by the method contains 56 volatile aroma substances, the taste and flavor of the hon
