Acetification refers to the process of turning a liquid into vinegar, and an acetifier is a device used to facilitate that process. Some synonyms for an acetifier could be vinegar-making apparatus or vinegar generator. Other related terms could include vinegar fermenter, acidifier, or acid generator. The word "acetify" could also be considered a synonym to describe the process of acidification. Acetifiers can come in different shapes and sizes, from small home-use devices to large industrial-scale ones. Regardless of the terminology used, the purpose of an acetifier remains the same, which is to convert alcohol-containing liquids into vinegar through the action of airborne bacteria.
