Prohibition
Prohibition in the United States focused on the manufacture, transportation, and sale of alcoholic beverages; however, exceptions were made for medicinal and religious uses. Alcohol consumption was never illegal under federal law. Nationwide Prohibition did not begin in the United States until January 1920, when the Eighteenth Amendment to the U.S. Constitution went into effect. The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Old Forester
Until Prohibition in the United States began in 1920, Old Forester was the leading brand produced by Brown's company. Since then, other brands acquired later by the company, such as Early Times (purchased in 1923, which became America's best-selling bourbon and maintained high sales for 30 years), and Jack Daniel's (purchased in 1956 and as of 2007 the best-selling whiskey of any kind in the world), have become its leading products.
