Old Forester is a brand of Kentucky straight bourbon whiskey produced by the Brown–Forman Corporation. It has been on the market continuously for longer than any other bourbon (approximately 150 years as of 2020), and was the first bourbon sold exclusively in sealed bottles. It was first bottled and marketed in 1870 by the former pharmaceutical salesman turned bourbon-merchant George Garvin Brown — the founder of the Brown–Forman Corporation (whose descendants still manage the company). During the Prohibition period from 1920 to 1933, Brown–Forman received one of only six licenses authorizing lawful production (for medicinal purposes).
