A method for preparing a fermented drink is described. The method comprises the initiation of fermentation by inoculating the fermentable drink with fermentative bacteria in the form of biofilm.

The object of the present invention is to provide an artisanal process for the manufacture of wine vinegar comprising the steps: a) dilution of the selected wine as raw material between 30 and 70%; b) preparation of the inoculum which includes acetic bacteria of the genera Acetobacter and Gluconobacter; c) addition of the wine of step a) and 10% to 30% of the inoculum selected from step b), into a fermenter; d) starting the fermentation with recirculation of the liquid; e) control of alcohol content up to 1%; f) addition of wine diluted to 50% when the amount of alcohol approaches 1%; g) completion of the fermentation when the total usable volume of the fermenter is reached and the alcohol concentration is less than 1% and acidity equal to or greater than 6%. It is further an object of the present invention a vinegar produced by the process disclosed therein.
