Newcastle Brown Ale is a brown ale, originally brewed in Newcastle upon Tyne, England. Launched in 1927 by Colonel Jim Porter after three years of development, the 1960 merger of Newcastle Breweries with Scottish Brewers afforded the beer national distribution and sales peaked in the United Kingdom in the early 1970s. The beer underwent a resurgence in the late 1980s and early 1990s with student unions selling it. By the late 1990s, the beer was the most widely distributed alcoholic product in the UK. By the 2000s, the majority of sales were in the United States, although it still sells 100 million bottles annually in the UK. Brewing moved in 2005 from Newcastle to Dunston, Tyne and Wear, and in 2010 to Tadcaster. In 2017, the Heineken Brewery in Zoeterwoude, the Netherlands, also began production. As of 2019, it is brewed as well by Lagunitas Brewing Company in Petaluma, California, and Chicago, Illinois, for the American market.
Newcastle Brown Ale is perceived in the UK as a working-man's beer, with a long association with heavy industry, the traditional economic staple of the North East of England. In export markets, it is seen as a trendy, premium import and is predominantly drunk by the young. It was one of the first beers to be distributed in a clear glass bottle and is most readily associated with this form of dispense in the UK.
