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 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 9,118 micro breweries, brewpubs, and regional craft breweries in the United States by the end of 2021.
