History of American Light Lager - CORRECT ANSWER - Coors briefly made a light

Modern versions were first produced by Rheingold in 1967 to appeal to diet-conscious drinkers,
but only became popular starting in 1973 after Miller Brewing acquired the recipe and marketed
the beer heavily to sports fans with the "tastes great, less filling" campaign. Beers of this genre
became the largest sellers in the United States in the 1990s.
History of American Lager - CORRECT ANSWER - Although German immigrants had
brewed traditional Pilsner-inspired lager beer in the United States since the mid-late 1800s, the
modern American lager style was heavily influenced by Prohibition and World War II. Surviving
breweries consolidated, expanded distribution, and heavily promoted a beer style that was
appealing to a broad range of the population. Became the dominant beer style for many decades,
and spawning many international rivals who would develop similarly bland products for the
mass market supported by heavy advertising.

International Pale Lagers often created by the same large, industrial breweries and meant to
appeal to a broad audience. Often either a colored or sweetened adaptation of the standard pale
industrial lager, or a more broadly accessible (and inexpensive) version of more traditional dark
lagers.
History of Czech Pale Lager - CORRECT ANSWER - Josef Groll initially brewed two
types of beer in 1842-3, a výčepní and a ležák, with the smaller beer having twice the
production; Evan Rail speculates that these were probably 10 °P and 12 °P beers, but that the
výčepní could have been weaker. This is the most consumed type of beer in the Czech Republic
at present.

still mainly of the traditional amber style, as are US-produced interpretations. Paulaner first
created the golden version in the mid-1970s because they thought the traditional Oktoberfest was
too filling. So they developed a lighter, more drinkable but still malty version that they wanted to
be "more poundable" (according to the head brewer at Paulaner). But the actual type of beer
served at Oktoberfest is set by a Munich city committee.
