Abstract
The disclosure relates to a reactive distillation method for beverage spirit production, the method comprising. An initial reaction mixture includes water, ethanol, and a carboxylic acid, for example having 3 or more carbon atoms. The reaction mixture is reactively distilled in the presence of an esterification catalyst to react a portion of the ethanol and the carboxylic acid to form an ethyl carboxylate reaction product, and form a distillation product or distillate including water, ethanol, and the ethyl carboxylate. The esterification catalyst is not present in the distillation product, for example when using a solid acid esterification catalyst in the reaction mixture. In a refinement, ethanol and the carboxylic acid can be co-fermented in an initial grain mixture, which is subsequently reactively distilled according to the disclosed method.
