Thanks GW. Since the monks are a simple people, they do not have indoor plumbing and anyone who has to go, uses the outhouse (not shown).

I did intend to use "draff". Water and malted barley go into the tun and the mixture is heated with steam from the boiler. When the brew leaves the tun, it goes through a series of filters to the boiler where hops are added. These filters catch the dregs of the malted pale-barley husks, otherwise known as draff. This draff is scraped off the filters and removed from the building out the north door. It makes a very high quality animal feed and is used by the monks to feed their goats.
