Difference between lager and beer? In short, all lager is beer, but not all beer is a lager. Both are a collective name for bottom-fermenting beer types. Pilsner, helles lager, Dortmunder, bock and Märzen are examples of beers that are part of the lager family.
Lager is beer which has been brewed and conditioned at low temperature. Lagers can be pale, amber, or dark. Pale lager is the most widely consumed and commercially available style of beer.
