We used to sell it at a bottle shop I worked at when in was younger. Iirc it was called polmos spyritus and came in a 500ml bottle and was 95%. The only bloke who used to buy it combined it with sugar and lemon to make his own limoncello.
I tried it once, it just burned and wasnt enjoyable at all
I think that is what's its meant for.. I remember it used to have a skull and cross bones poison logo in the description
