                                According to a study on hangovers comparing high-congener bourbon and low-congener vodka, subjects reported more severe symptoms after drinking the bourbon, showing that the type of alcohol matters. The primary culprits are chemically complex compounds called congeners, which are present in varying amounts across different spirits.
