The first Redbreast whiskey was released by W&A Gilbey, a wine merchant and importer, in 1903 under the name “John Jameson & Sons Castle JJ Liqueur Whiskey 12 Year Old” though it wasn’t known under the Redbreast name until 1912, so named due to the chairman of Gilbey’s being a bird enthusiast. While the sourcing of Redbreast has changed more than once it is currently distilled at the New Midleton Distillery after the Jameson Bow Street Distillery closed. The Redbreast line is the largest selling single pot still Irish whiskey in the world. The Redbreast 15 is comprised of malted and unmalted barley and has been matured in a mixture of both ex-bourbon and ex-sherry casks, like all Redbreast whiskies.
