Considerations on the Convenience of Distilling at High Proof in Continuous Alcoholic Distillation for Beverages

Abstract

The results of these studies on the distribution of congenerics along continuous distillation columns, as well as previously published results on the distribution of fusel oil under different operating conditions, indicate the convenience of distilling at the highest possible proof within the limits established by the Law. By distilling at higher proof, and by properly selecting other operational variables, it is possible to recover congeneric substances to any desired extent while reducing the content of fusel oil and unidentified tail substances in the main product. It is recognized that the presence of the latter detracts from the quality of alcoholic beverages.
