William Key took over the running of the Anstruther and Crail Breweries in 1874, following the death of his brother, John Melville Key. He continued to run the Crail Brewery under the partnership of James Key & Son, but ran the Anstruther Brewery under his own name.
The trademark of the business was a key on a background of barley.
When he retired in 1905 he sold off the Anstruther Brewery and associated aerated water interests, and handed over management of the Crail Brewery to his brother, Thomas.
Amongst the beers produced by the brewery was Double Brown Stout.
The Crail Brewery was situated on the High Street and consisted of a group of buildings organised around a courtyard.
The Anstruther Brewery was on Burial Brae, and consisted of a group of buildings organised around a courtyard.
