Question: Beer Wars covers differences between big breweries and small breweries like this one based in Milton, Delaware founded by Sam Calagione that opened in what year
Context: Beer, called maekju (맥주 ; 麥酒 ) in Korean, was first introduced to Korea in the early 20th century.  Seoul's first beer brewery opened in 1908.  Two current major breweries date back to the 1920s.  The third brewery established in Korea, Jinro Coors Brewery, was founded in the 1990s.  It was later acquired by Oriental Breweries (OB).  Hite Breweries's former name was Chosun Breweries, which was established in 1933.  The company changed their name to Hite Breweries in 1998.  OB Breweries established as Showa Kirin Breweries in 1933.  The company changed their name to OB Breweries in 1995. This is a list of notable microbreweries.  A microbrewery is a brewery which produces a limited amount of beer.  The qualifications to be classified as a microbrewery vary by country.  The term "microbrewery" originated in the United Kingdom in the late 1970s to describe the new generation of small breweries which focused on producing traditional cask ale.  The first successful example of this approach was Litchborough Brewery founded by Bill Urquhart in 1975 in the Northamptonshire village of the same name.  Although originally "microbrewery" was used in relation to the size of breweries, it gradually came to reflect an alternative attitude and approach to brewing flexibility, adaptability, experimentation, and customer service.  The term and trend spread to the United States in the 1980s, where it eventually was used as a designation of breweries that produce fewer than 15,000 U.S. beer barrels (1,800,000 liters) (475,000 U.S. gallons) annually. Dogfish Head Brewery is a brewing company based in Milton, Delaware founded by Sam Calagione.  It opened in 1995 and produces 262,000 barrels of beer annually.  Dogfish Head has been a rapidly growing brewery – it grew nearly 400% between 2003 and 2006.  The brewery was featured prominently in the documentary "Beer Wars" and was the subject of the Discovery Channel series "Brew Masters", which premiered Sunday, November 21, 2010.  The brewery takes its name from Dogfish Head, Maine where Calagione spent summers as a child. Namibia Breweries Limited (NBL) is a Namibian brewery founded in 1920 when Carl List and Hermann Ohlthaver acquired four small breweries with financial difficulties.  The breweries were merged under the name South West Breweries Limited (SWB).  SWB changed its name to Namibia Breweries Limited when Namibia gained independence on March 21, 1990.  Ohlthaver & List Group of Companies are still the majority shareholder. Brew Masters is a television series that was run weekly on Discovery Channel starting on Sunday, November 21, 2010.  The show focused on Sam Calagione, the founder and head of Dogfish Head Brewery in Milton, Delaware, and his staff as they searched the world for new, ancient, and imaginative inspirations for beers. This is list of breweries in South Dakota.  South Dakota is one of 14 U.S. states that forbids small breweries from directly distributing beer products.  Small breweries are required to use a distributor, per South Dakota law. San Diego County, California has been called "the Craft Beer Capital of America."  As of 2016 the county was home to 125 licensed craft breweries - the most of any region in the United States.  Based on 2016 sales volume, three San Diego County breweries - Stone, Green Flash, and Karl Strauss - rank among the 50 largest craft brewers in the United States.  San Diego County brewers pioneered the specialty beer style known as Double India Pale Ale (Double IPA), sometimes called San Diego Pale Ale.  Its beer culture is a draw for tourism, particularly during major festivals such as San Diego Beer Week and the San Diego International Beer Competition.  San Diego County breweries like Stone Brewing Co., AleSmith Brewing Company and Ballast Point Brewing Company are consistently rated among the top breweries in the world. This list of breweries in California, both current and defunct, includes both microbreweries and larger industrial scale breweries.  Brewing companies range widely in the volume and variety of beer produced, ranging from small breweries to massive multinational conglomerates.  Since 1983, California has allowed breweries to sell beer on their premises, giving rise to numerous brewpubs and microbreweries. Luxembourg has a long tradition of beer brewing, dating back to at least 1300.  Although there used to be more than 12 local breweries in Luxembourg in the early 1950s, this number has come down to only three big breweries remaining in the early 2010s.  The three big breweries still active today are: Brasserie Nationale, producing "Bofferding" and "Battin", Brasserie de Luxembourg (owned by Anheuser-Busch InBev), producing "Diekirch" and "Mousel", and Brasserie Simon, producing "Simon" and "Ourdaller" (and "Okult"). Beer Wars is a 2009 documentary film about the American beer industry.  In particular, it covers the differences between large corporate breweries, namely Anheuser-Busch, the Miller Brewing Company, and the Coors Brewing Company opposed to smaller breweries like Dogfish Head Brewery, Moonshot 69, Yuengling, Stone Brewing Co., and other producers of craft beer.  Also covered is how advertising and lobbyists are used to control the beer market, implying that these things harm competition and consumer choice.
