Lager Vs Pilsner: What's The Difference?

What is lager?

Lager is the broad category of beers fermented with bottom-fermenting yeast strains (Saccharomyces pastorianus) at cooler temperatures (45-55 degrees F). The name comes from German 'lagern' meaning 'to store,' referring to the traditional long aging in cold cellars. Lager fermentation takes 4-8 weeks total, much longer than ale fermentation. The cool temperatures and yeast strain produce cleaner, crisper, more delicate flavors than ales, with fewer fruity esters. Lager styles range widely: pilsner (light and hoppy), Munich helles (pale and malty), Vienna lager (amber and balanced), Oktoberfest/Marzen (amber and richer), bock and doppelbock (strong and malty), American light lager (pale and light-bodied), and Czech dark lager (dark with malty depth). About 90 percent of global commercial beer is lager.

What is pilsner?

Pilsner is a specific style of pale lager that originated in 1842 in the Czech town of Pilsen (Plzen), where the Pilsner Urquell brewery developed the style. Pilsner is characterized by very pale golden color, strong hop bitterness (particularly from Saaz noble hops), crisp clean malt flavor, and a dry finish. Pilsner ranges from 4.4-5.5 percent ABV typically. The style transformed beer worldwide; before pilsner, most beer was dark and cloudy. There are two main pilsner sub-styles: Czech pilsner (Bohemian, like Pilsner Urquell or Budweiser Budvar, slightly fuller and sweeter); German pilsner (drier, more bitter, lighter-bodied, like Bitburger or Beck's). American mass-market 'pilsners' (Bud, Coors, Miller) are technically pale lagers but typically lack the hop bitterness of true Czech or German pilsners.

How do lagers and pilsners compare?

All pilsners are lagers, but only specific lagers qualify as pilsners. The distinguishing characteristics of pilsner among lagers: very pale golden color (not amber, dark, or hazy); pronounced hop bitterness (25-45 IBU vs 5-25 for most other lagers); use of Saaz or similar noble hops; crisp dry finish. Compared to other common lager styles: pilsners are hoppier and drier than American light lagers (which are sweeter and less bitter); pilsners are lighter than Vienna or Marzen lagers (which are amber and maltier); pilsners are paler than Munich dunkel (dark lager). Compared to ales overall: lagers (including pilsners) are cleaner and crisper than ales, which have more fruity esters and complex aromas. ABV is similar across pilsners and most lagers (4-5 percent).

Can you tell pilsner from other lagers?

Several characteristics distinguish true pilsner from generic lager. Color: pilsners are very pale golden; many lagers are slightly darker or amber. Bitterness: pilsners taste distinctly bitter from hops; American light lagers are barely bitter. Hop aroma: pilsners have noticeable noble hop aroma (slightly herbal, spicy, floral); generic lagers have minimal hop character. Carbonation: pilsners have crisp, fine bubbles; some lagers have heavier carbonation. For verification, the label often specifies: 'Czech pilsner,' 'German pilsner,' or just 'pilsner' indicates the style; 'lager' without further specification often means a generic American or international lager. Famous true pilsners include Pilsner Urquell (Czech), Budweiser Budvar (Czech), Bitburger (German), and many craft brewery versions.
