All I know anyway is that Poitín in Ireland has always been taken to mean the stuff made in home distilleries and considered absolutely lethal. There are commercially produced versions now but everyone knows they're not 'the real thing'.
No wonder you have such a raspy voice.
He may have scar tissue on his larynx. I once knew a doctor, an ear, nose and throat specialist and he told me that one of the main functions of the larynx is fixation of the chest for lifting heavy weights. The fact that we can produce sound with it is just an added bonus. He said that people who do a lot of heavy lifting often damage the larynx without knowing it and can have very raspy voices which are mistaken for what he called 'a typical beer voice'. Anyway if Delph has ever put in a few months of heavy lifting, that could be the reason for his raspiness!
