George Killian’s Irish Red is a beer with an Irish heritage, based on a recipe created at Lett’s Brewery in Enniscorthy, Ireland, in 1864. It was originally an Irish red ale. Coors acquired the rights to brew and market the product in America from France’s Pelforth Beer Company who currently owns the rights to George Killian’s Irish Red.

Coors initially introduced and marketed it to the U.S. in 1981; the product was introduced and labeled as an ale, with a fruity flavor profile as per the style, but for marketing purposes the product was eventually toned down somewhat, and George Killian’s was re-formulated and re-labeled by Coors from an ale to a lager style brew.
