Homebrewing

Homebrewing is the brewing of beer or other alcoholic beverages on a small scale for personal, non-commercial purposes. Supplies, such as kits and fermentation tanks, can be purchased locally at specialty stores or online. Beer was brewed domestically for thousands of years before its commercial production although its legality has varied according to local regulation. Homebrewing is closely related to the hobby of home distillation, the production of alcoholic spirits for personal consumption, but home distillation is generally more tightly regulated.

Beer has been brewed domestically throughout its 7,000-year history, beginning in the Neolithic period in Mesopotamia (modern Iraq), Egypt and China. It seems to have first developed as thick beers; during this time meads, fruit wines and rice wines were also developed.

Women brewers dominated alcohol production on every occupied continent until commercialization and industrialization of brewing occurred. The tradition of brewing being in the domain of women stemmed from the fact that brewing was a by-product of gathering, and often considered a part of baking.

The Greeks and Romans cultivated both grape wine and beer, to a lesser extent. Roman women often directed production in larger households while the labor was performed by slaves.

By the Tang dynasty, homebrewing seems to have been a familiar domestic chore in China, albeit the lower classes had to make do with poorly-filtered mash. Laws against making alcohol were enacted and repealed between the Zhou and Ming dynasties.^{[citation needed]}

The 18th century Industrial Revolution brought about such innovations as the thermometer and hydrometer. These tools increased efficiency to the point that mass production of beer was possible for the first time in history^{[citation needed][clarification needed]}. In 1857, French microbiologist Louis Pasteur explained the role of yeast in beer fermentation, allowing brewers to develop strains of yeast with desirable properties such as efficiency converting sugar to alcohol and ability to handle higher alcohol content.

Throughout the first half of the 20th century, homebrewing in the UK was circumscribed by taxation: the Inland Revenue Act 1880 (43 & 44 Vict. c. 20) introduced a 5-shilling homebrewing licence. Chancellor of the Exchequer Reginald Maudling removed the requirement for a brewing licence in 1963. Australia followed suit in 1972 when Gough Whitlam repealed the law prohibiting the brewing of all but the weakest beers in one of his first acts as Prime Minister.

In 1920, Prohibition caused breweries across the United States to be closed down or to begin making malt for other purposes. The homebrewing of beer with an alcohol content higher than 0.5% remained illegal until 1978 when Congress passed a bill repealing federal restrictions and excise taxes, and President Jimmy Carter signed the bill, H.R. 1337, into law, legalizing homebrewing of beer in the United States. Within months of homebrewing's full legalization, Charlie Papazian founded the Brewers Association and American Homebrewers Association. In 1984, Papazian published The Complete Joy of Home Brewing, which remains in print alongside later publications, such as Graham Wheeler's Home Brewing: The CAMRA Guide.
