Beer in the United States
On January 16, 1919, the Eighteenth Amendment to the United States Constitution was enacted into law, creating the Prohibition era, wherein the production, sale and transportation of alcoholic beverages was made illegal. All legal American brewing came to a halt when prohibition was imposed, though the earlier temperance movement had already reduced the number of breweries significantly. Only a few breweries, mainly the largest, were able to stay in business by manufacturing near beer, malt syrup, or other non-alcohol grain products, in addition to soft drinks such as colas and root beers. Production and shipping of alcohol was largely confined to illegal operations that could deliver compact distilled beverages—smuggled rum and domestic moonshine—more efficiently and reliably than bulkier products such as beer.
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.
