A distiller's parrot is a piece of equipment that allows you to take alcohol gravity measurements using an Alcometer continuously throughout your pot or reflux run. It should be placed inline of your distillation outlet so that the drops of distillate fall directly into the tallest collection cone. But it should only placed in-line after you collect your foreshots. Your alcometer is then gently placed into the lower cone. Be careful not to drop in the alcometer before there is any liquid/distillate in the cone, as dropping it into an empty cone could break your glass alcohol meter.
