The
lagering process produces a crisper, "colder" taste.
mbms characterization of lagers is unfair. Many high-quality lagers exist; dark lagers and heavy-bodied lagers, while
rare, are a unique and satisfying alternative to craft-brewed
ales.
For many decades, lagers dominated the
American beer market. This ended (thank
God) with the micro- and craft-brewing revolution in the early 1990's, when
ales once again became popular.
Perhaps
mbm is thinking of the
Pilsner style of beer, which is always light-bodied and rather bland.
Pilsners are a type of lager, and the qualities of the two are often confused.
