Keighley's award winning Timothy Taylor brewery is preparing for the visit on Monday of Prince Charles.
The Prince is due to arrive at the Knowle Spring Brewery, in Belina Street, at 10.30am.
He will spend about an hour and a quarter at the site, meeting staff and viewing the various stages of the brewing process.
The Prince will then head off to the Bradford Urban Village, in the Little Germany area of the city.
Taylor's managing director Charles Dent says the firm will be preparing a few drinks for the royal visitor to sample.
"We are very honoured and delighted with the visit," says Mr Dent.
The Taylor family began making beer in Keighley in 1858 and moved to the Knowle Spring site five years later. It is one of the last remaining independent breweries in West Yorkshire and has collected countless top awards for its ales.
