Most low-alcohol beers are lagers, but there are some low-alcohol ales.

Document 5: List of breweries in Australia: Beer production in Australia has traditionally been dominated by regional producers. Since the 1980s there has been a steady stream of takeovers and amalgamations, and now the two major producers (who were once Australian owned) are Carlton & United Breweries (CUB) and Lion. In December 2011, CUB became a subsidiary of British multinational SABMiller (the then world second largest international brewing company) and in October 2016 CUB became 100% owned by Anheuser-Busch InBev (AB InBev) the world's largest brewing company based in Belgium. Since October 2009, Lion has been a subsidiary of Japanese brewer, Kirin Holdings Company Limited a brewing company established in 1885. The largest remaining Australian owned brewer is Coopers Brewery with a market share of about 4% of total beer volume sales in Australia.
Document 6: Cream ale: Cream ale is a style of American and Canadian beer, of which examples are often light in color and are well attenuated. First crafted in the mid-1800s at various breweries in the United States, and in Canadian breweries such as Sleeman, cream ale remained a very localized form with different styles until the early 20th century. During Prohibition in the United States, a great number of Canadian brewers took up brewing cream ale, refining it to some degree. Following the end of Prohibition in the United States, cream ale from Canada became popular and the style was produced anew in both nations.
Document 7: Beer in Canada: Beer in Canada was introduced by European settlers in the seventeenth century. The first commercial brewery was La Brasseries due Roy [sic] started by New France Intendant Jean Talon, in Québec City in 1668. Many commercial brewers thrived until Prohibition in Canada. The provincial and federal governments' attempt to eliminate "intoxicating" beverages led to the closing of nearly three quarters of breweries between 1878 and 1928. It was only in the second half of the twentieth century that a significant number of new breweries opened up. The Canadian Beer industry now plays an important role in Canadian identity, though globalization of the brewing industry has seen the major players in Canada acquired by, or merged with, foreign companies, notably its three largest beer producers, Labatt, Molson and Sleeman. The result is that Moosehead, with an estimated 3.8 percent share of the domestic market in 2016, has become the largest fully Canadian-owned brewer.

Document 9: Kentucky common beer: Kentucky Common Beer is a once-popular style of ale from the area in and around Louisville, Kentucky from the 1850s until Prohibition. This style is rarely brewed commercially today. It was also locally known as "Dark Cream Common Beer", "Cream Beer" or "Common Beer". The beer was top-fermented and wasn't krausened, i.e., it was fermented once and sent out for sale which meant the gravity would be moderate, the carbonation low and the taste full and sweetish. Like cream ale, it was consumed fresh, usually as draught beer. In 1913 it was estimated that 80% of the beer consumed in Louisville was of this type. Many local breweries made this style of beer exclusively.
Document 10: Beer in Luxembourg: 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").

Document 12: Beer in Mexico: Beer in Mexico has a long history. While Mesoamerican cultures knew of fermented alcoholic beverages, including a corn beer, long before the Spanish conquest, European style beer brewed with barley was introduced with the Spanish soon after Hernán Cortés’s arrival. Production of this beer here was limited during the colonial period due to the lack of materials and severe restrictions and taxes placed on the product by Spanish authorities. After the Mexican War of Independence, these restrictions disappeared, and the industry was permitted to develop. Furthermore, the arrival of German immigrants and the short-lived empire of Austrian Maximilian I in the 19th century provided the impetus for the opening of many breweries in various parts of the country. By 1918, there were 36 brewing companies, but over the 20th century, the industry consolidated until today, only two corporations, Grupo Modelo and FEMSA control 90% of the Mexican beer market. This industry is one of the most prevalent in the country, with over 63% of the population buying one brand or another. Beer is also a major export for the country, with most going to the United States, but is available in over 150 countries in the world.
Document 13: American lager: American lager or North American lager is pale lager that is produced in North America. Pale lager originated in Europe in the mid-19th century, and moved to America with German immigrants. As a general trend outside of Bavaria and the Czech Republic where the beers may be firmly hopped, pale lager developed as a modestly hopped beer, and sometimes used adjuncts such as rice or maize – and this was also true in America.

The brewery was founded in 1867 and is still privately owned and operated by the Oland family. Now in the sixth generation of family ownership, this is a privately held company. The Moosehead line of beer is extensive, and includes American beers brewed under license for four major U.S. companies. Moosehead beer is sold throughout Canada, in many locations in the United States and in 15 countries around the world.
Document 15: Carling brewery: Carling brewery was founded in London, Ontario, Canada in 1818. In 1952 Carling lager was first sold in the United Kingdom; in the early 1980s it became the UK's most popular beer brand (by volume sold). The company changed hands numerous times; it was acquired by Canadian Breweries Limited, which was eventually renamed Carling O'Keefe, which merged with Molson, which then merged with Coors to form Molson Coors Brewing Company. In South Africa the Carling brands are distributed by SABMiller.
