“It has always been assumed that the treacle is the remains of thickets of sugar cane crushed by mud at about the same time as cola measures were being laid down. It was – and still is, in some parts of the Disc – mined either as a solid, which has to be cleaned & refined and cast in slabs (“pig treacle” or “Hokey Pokey”) and, very rarely, as a liquid. In the area around Genua, liquid treacle lakes near the surface have absorbed enough moisture to ferment naturally, giving rise to occasional springs of rum as the results burst forth under pressure.” The Discworld Companion, Terry Pratchett & Stephen Briggs, 1994.
