Is homebrewing legal?
In a word, yes. In 1978 a U.S. federal law that allowed home winemaking after the end of Prohibition was amended to include homebrewing of beer. The law allows for up to 100 gallons annually per adult member of each household, with a maximum total of 200 gallons per household. Individual states also have passed laws specifically allowing homebrewing; as of January 2004, all but six (Alabama, Iowa, Kentucky, Mississippi, Oklahoma, Utah) have done so. Even in those states there have been no active prosecutions of homebrewers; homebrew shops and clubs continue to operate openly and without interference except in a few cases on very specific issues such as competitions. Home distillation (as opposed to fermentation) of alcohol is forbidden in the U.S. and all but a very few other countries.
