Homebrewing beer becomes federally legal on February 1, 1979. When Prohibition ended, federal law allowed households to produce wine for personal use but that was not the case for beer, which remained illegal to brew at home.
On October 14, 1978, President Jimmy Carter signed H.R. 1337 which federally legalized homebrewing of beer, effective on February 1, 1979. The law allowed hobbyists to brew 100 gallons of alcohol or 200 gallons per household annually for personal or family consumption.. It was not until 2013 that all 50 states allowed homebrewing of beer. The legalization fueled the American craft beer revolution which had been underway for almost 20 years. The American Homebrewers Association formed at the end of 1978.
