In 1979, Carter deregulated the American beer industry by making it legal to sell malt, hops and yeast to American home brewers for the first time since the effective 1920 beginning of Prohibition in the United States. This Carter deregulation led to an increase in home brewing over the 1980s and 1990s that by the 2000s had developed into a strong craft microbrew culture in the United States, with 3,418 micro breweries, brewpubs and regional craft breweries in the United States by the end of 2014.
