The term 'Bit of Brewing Equipment' can be summarized as an OAST, which is a four-letter word. An OAST is a kiln used in the brewing process to dry hops. It is typically a tall building with a conical roof and a rotating cowl at the top. The cowl is used to draw off the hot air from the kiln, which is then used to dry the hops. The dried hops are then used in the brewing process to add flavor and aroma to beer.
