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, 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. During the Prohibition period from 1920 to 1933, Brown-Forman received one of only six licenses authorizing lawful production.
