Cover Story: The distillates of a fermented mash from a 5-gallon pot still were characterized using 1H NMR spectroscopy and GC-MS. Key congeners, such as acetaldehyde, ethyl acetate, furfural, phenylethanol, and 1,1-diethoxyethane, showed expected distillation behavior across ten fractions, based on their respective pure-component boiling points. However, methanol and 1-propanol showed a fairly flat concentration profile across all ten fractions. White dog (unaged whiskey) fractions from column and combination stills were also analyzed, and the results demonstrate that the small 5-gallon still separates congeners as well as these stills. Our data show that while GC-MS and NMR do reveal similar overall trends in congener concentrations across the distillation fractions, the concentration magnitude, as determined from these techniques, can vary.
