American lager

Pale lager is the predominant choice among the largest brewing companies of United States of America, although it is not common in U.S. microbreweries.

Likewise, in Canada the biggest-selling commercial beers, including both domestics such as Molson Canadian, Labatt Blue, Kokanee, Carling Black Label, and Old Style Pilsner, and imports such as Budweiser and Coors are very lightly hopped pale lagers.

Therefore, to balance taste, and dilute the excessive protein, the grain mixture was adjusted by adding up to 30% corn to the barley malt mash.

Later, rice gained popularity in the domestic brewing market during World War II, due to grain rationing on the home-front.

Canada had its own, shorter experiment with prohibition which bankrupted many breweries (and distilleries), and with the rise of mass media marketing and national-scale supply chains, the major breweries consolidated into a near triopoly dominated by Molson, Labatt, and Carling O'Keefe following the Second World War.
