At the close of Prohibition the brand's owners, the Mellon family, sold Old Overholt to National Distillers who continued to produce it for the next half century despite declining popularity in rye whiskey in US after the second world war. Whilst the last National Distillers facility in Pennsylvania closed in 1951, the whisky was still produced in the state up until 1987 when Jim Beam acquired the brand so it is unclear where they were distilling the brand by this point. Candidates include Schenley, Pennco (Michter's) Kinsey or Continental. 

Old Overholt nowadays is distilled in Kentucky, produced alongside Old-Grandad by Jim Beam, who acquired both of 'The Olds' from National Distillers.
