congener

This dual capacity distinguishes us from other species which, to learn a new task, need numerous trials accompanied by positive or negative reinforcement signals, without being able to communicate it to their congeners.

The usual suspects, however, are not the alcohol molecules but the enigmatic chemicals known as congeners.

The type of still will influence the beverages’ final flavor, because pot stills often do not separate the congeners as precisely as column stills do.

The type of beverage you drink also matters: Tequila, whiskey and darker alcohols contain compounds called congeners, which are more likely to bring on longer-lasting hangovers because of how they are metabolized, Roberts said.
