Many breweries around the world brew a stronger version of their regular lager. For the US there is the Ice Beer & Malt Liquor, both have a high amount of rice or corn to lighten the flavor. Many European & Asian breweries have a strong lager similar to the Malt Liquor though there is more malt use or it is all malt. Many breweries rush the fermentation or the brew will be too light and signs of higher alcohols will be noticed in the aroma and flavor.
