Malt-drying kiln

OAST

This structure with a conical roof is often found on farms in Kent, used in the brewing process before hops are added.

"Malt-drying kiln" points to "OAST," a term for the traditional conical buildings used in brewing to dry malted barley. The word is most common in British English, especially in regions like Kent where hops are grown. It’s a straightforward definition with no wordplay—just a direct link between the function (drying malt) and the structure’s name. If you’ve seen old brewery buildings with white, tapered towers, those are likely oast houses.
