Labatt Brewing Company Ltd. (French: Brasseries Labatt du Canada Ltée) is a Belgian-owned Canadian beer company founded by John Kinder Labatt in 1847 in London, Ontario. In 1995, it was purchased by Belgian brewer Interbrew; it is now part of Anheuser-Busch InBev. Labatt is the largest brewer in Canada.
In the United States, Labatt brand beers are sold under license by Labatt USA, which since 2009 has been fully independent of the Canadian firm and a subsidiary of the privately held North American Breweries of Rochester, New York.
In 1901, Prohibition began in Canada through a provincial legislation in Prince Edward Island. In 1916, prohibition was instituted in Ontario as well, affecting all 64 breweries in the province. Although some provinces totally banned alcohol manufacture, some permitted production for export to the United States. Labatt survived by producing full strength beer for export south of the border and by introducing two "temperance ales" with less than two per cent alcohol for sale in Ontario. However, the Canadian beer industry suffered a second blow when Prohibition began in the U.S. in 1919. When Prohibition was repealed in Ontario in 1926, just 15 breweries remained and only Labatt retained its original management. This resulted in a strengthened industry position. In 1945 Labatt became a publicly traded company with the issuance of 900,000 shares.
A brewery or brewing company is a business that makes and sells beer. The place at which beer is commercially made is either called a brewery or a beerhouse, where distinct sets of brewing equipment are called plant. The commercial brewing of beer has taken place since at least 2500 BC; in ancient Mesopotamia, brewers derived social sanction and divine protection from the goddess Ninkasi. Brewing was initially a cottage industry, with production taking place at home; by the ninth century monasteries and farms would produce beer on a larger scale, selling the excess; and by the eleventh and twelfth centuries larger, dedicated breweries with eight to ten workers were being built.
The diversity of size in breweries is matched by the diversity of processes, degrees of automation, and kinds of beer produced in breweries. A brewery is typically divided into distinct sections, with each section reserved for one part of the brewing process.
Beer may have been known in Neolithic Europe and was mainly brewed on a domestic scale. In some form, it can be traced back almost 5000 years to Mesopotamian writings describing daily rations of beer and bread to workers. Before the rise of production breweries, the production of beer took place at home and was the domain of women, as baking and brewing were seen as "women's work".
