A rare 1972 vintage from Glengoyne, packaged in a glass fronted lockable safe. All spirit stills have a brass bound, glass walled container which allows the distiller to analyse the spirit coming off the stills, the safe is padlocked to prevent the distiller actually coming into contact with the spirit. Originally, only an Exciseman would keep the key, to prevent anyone taking spirit from the still without paying tax.
