Quality, from a flavor point of view, is very variable within this style and many cheaper examples use a proportion of non-malt additives such as rice or corn to reduce the production costs. Pilsner styles of beer originate from Bohemia in the Czech Republic. They are medium to medium-full bodied and are characterized by high carbonation and tangy czech varieties of hops that impart floral aromas and a crisp, bitter finish. The hallmark of a fresh pilsner is the dense, white head. Classic pilsners are thoroughly refreshing, but they are delicate and must be fresh to show their best.
Few beers are as disappointing to the beer lover as a stale pilsner.
German pilsner styles are similar, though often slightly lighter in body and color. Great pilsners are technically difficult to make and relatively expensive to produce. The classic amber to red lager which was originally brewed in Austria in the 19th century has come to be known as the Vienna style. These are reddish-amber with a very malty toasted character and a hint of sweetness. This style of beer was adapted by the Munich brewers and in their hands has a noted malty sweetness and toasted flavor with a touch more richness.
