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; however 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 Laws against making alcohol were enacted and repealed between the Zhou and Ming dynasties.
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. 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.

Beer has been brewed in England for thousands of years. As a beer brewing country, it is known for top fermented cask beer (also called real ale) which finishes maturing in the cellar of the pub rather than at the brewery and is served with only natural carbonation. English beer styles include bitter, mild, brown ale and old ale. Stout, porter and India pale ale were also originally brewed in London. Lager-style beer has increased considerably in popularity since the mid-20th century.
thumb|Deux verres de boissons alcoolisées. Une boisson alcoolisée, ou boisson alcoolique, ou un alcool, est une boisson contenant de l'éthanol. Le vin, la bière, l'eau-de-vie, sont des exemples de boissons alcoolisées. Le goût, mais aussi l'effet psychodysleptique de l'éthanol, peuvent participer à l'appétence pour ce type de boisson et motiver sa consommation. Celle-ci peut également être influencée par des facteurs sociaux tels qu'un contexte convivial offrant une disponibilité facile du produit, le mimétisme voire la pression de groupe, ou à l'inverse, la restriction voire l'illégalité de vente ou de consommation du produit.
