Sc brewland
This is the land connected with the brewing on the estate of Auchinleish. Archie Duncan has stated that ‘it is not in doubt that a large proportion, perhaps as much as a third, of grain grown was brewed into ale and drunk by cottars, husbandmen, lairds and lords. For the first of these at least it was the only alternative to water’ (Duncan 1975, 350-1).
