The oast meaning is a kiln, an oven-like chamber, used to dry hops after harvest, and sometimes malt or tobacco. The building that contains such a kiln is called an oast house, and in southern England people often shorten that to just "an oast".
It is a rare word in daily speech, but it is very well known in hop-growing country, in house-for-sale listings for converted farm buildings, and among people who solve crosswords, where its four letters come in handy.

Oast meaning: a closer look at the kiln
Ask a hop farmer to define oast and you will hear one phrase: a drying kiln. Fresh hop flowers, the soft green cones used to flavour and preserve beer, are very wet when picked and rot quickly. In an oast, they were spread on a floor above a heat source so warm air could rise through them and draw the moisture out. Once dry, the hops could be stored and sold to brewers.
The word can mean either the kiln itself or the whole building. Context usually makes it clear: "the oast was fired at dawn" points to the kiln; "they bought an old oast" points to the building.
What an oast house looks like
Traditional oast houses are easy to spot in the English countryside, especially in Kent and Sussex. Many have one or more round or square towers called kilns, often with a pointed roof. On top sits a white wooden cowl that turns with the wind to help draw air through the drying hops. Next to the kilns is a longer barn-like section, called the stowage, where the dried hops were cooled and packed into large sacks.

Where the word comes from
Few farm words are older. Oast traces back through Middle English ost to Old English ast, meaning a kiln. The Germanic root behind it is connected with fire and burning, and cousins survive elsewhere, for instance Dutch eest, a drying kiln. Its spelling changed over the centuries, but the meaning has stayed tied to drying with heat.
From working kiln to country home
As hop farming changed and drying moved to modern machines, many oasts lost their original job. Lots of them were converted into homes, holiday lets or offices. The round rooms and tall ceilings are popular, and estate agents in southern England list them as "converted oast houses". Because of this history, the word now carries a gentle feel of rural heritage and nostalgia for older farming life.
