An oast house is an example of
vernacular architecture in
England, especially
Kent and
Sussex. They are farm buildings used for drying
hops in preparation for the
brewing process. They consist of three or four storeys on which the hops were spread out to be dried by hot air from a wood or charcoal-fired
kiln at the bottom. The drying floors were thin and perforated to permit the heat to pass through and it escaped through a cowl in the roof which turned with the wind. The freshly picked hops from the fields were raked in to dry and then raked out to cool before being bagged up and sent to the brewery.
