Czech Lager

Czech lagers are generally divided by gravity class (draft, lager, special) and color (pale, amber, dark). The Czech names for these categories are světlé (pale), polotmavé (amber), and tmavé (dark). The gravity classes are výčepní (draft, 7–10 °P), ležák (lager, 11–12 °P), and speciální (special, 13 °P+). Pivo is of course the Czech word for beer. The division into gravity classes is similar to the German groupings of schankbier, vollbier, and starkbier, although at different gravity ranges. Czech beers within the classes are often simply referenced by their gravity. There are often variations within the gravity-color groupings, particularly within the speciální class. The style guidelines combine some of these classes, while other beers in the Czech market are not described (such as the strong Czech Porter). This is not to imply that the categories below are the full coverage of Czech beers, simply a way of grouping some of the more commonly found types for judging purposes.
Czech lagers in general are differentiated from German and other Western lagers in that German lagers are almost always fully attenuated, while Czech lagers can have a slight amount of unfermented extract remaining in the finished beer. This helps provide a slightly higher finishing gravity (and thus slightly lower apparent attenuation), slightly fuller body and mouthfeel, and a richer, slightly more complex flavor profile in equivalent color and strength beers. German lagers tend to have a cleaner fermentation profile, while Czech lagers are often fermented cooler (7–10 °C) and for a longer time, and can have a light, barely noticeable (near threshold) amount of diacetyl that often is perceived more as a rounded body than overtly in aroma and flavor [significant buttery diacetyl is a flaw]. Czech lager yeast strains are not always as clean and attenuative as German strains, which helps achieve the higher finishing gravity (along with the mashing methods and cooler fermentation). Czech lagers are traditionally made with decoction mashes (often double decoction), even with modern malts, while most modern German lagers are made with infusion or step infusion mashes. These differences characterize the richness, mouthfeel, and flavor profile that distinguishes Czech lagers.

Guidelines

Impression

A rich, dark, malty Czech lager with a roast character that can vary from almost absent to quite prominent. Malty balance and an interesting and complex flavor profile, with variable levels of hopping that provides a range of possible interpretations.

Aroma

Medium to medium-high rich, deep, sometimes sweet maltiness, with optional qualities such as bread crusts, toast, nuts, cola, dark fruit, or caramel. Roasted malt characters such as chocolate or sweetened coffee can vary from moderate to none but should not overwhelm the base malt character. Low to moderate spicy hop aroma optional. Low diacetyl and low to moderate fruity esters (plums or berries) may be present.

Appearance

Dark copper to almost black color, often with a red or garnet tint. Clear to bright clarity. Large, off-white to tan, persistent head.

Flavor

Medium to medium-high deep, complex maltiness dominates, typically with malty-rich Maillard products and a light to moderate residual malt sweetness. Malt flavors such as caramel, toast, nuts, licorice, dried dark fruit, chocolate, or coffee may also be present, with very low to moderate roast character. Low to moderate spicy hop flavor. Moderate to medium-low bitterness, but should be perceptible. Balance can vary from malty to relatively well-balanced to gently hop-forward. Low to moderate diacetyl and light plum or berry esters may be present.

Mouth Feel

Medium to medium-full body, considerable mouthfeel without being heavy or cloying. Moderately creamy in texture. Smooth. Moderate to low carbonation. Can have a slight alcohol warmth in stronger versions.

Comments

This style is a combination of the Czech styles tmavý ležák (11–12.9 °P) and tmavé speciální pivo (13–14.9 °P). More modern examples are drier and have higher bitterness while traditional versions often have IBUs in the 18–20 range with a sweeter balance.

History

The U Fleků brewery has been operating in Prague since 1499, and produces the best-known version. Many small, new breweries are brewing this style.

Ingredients

Pilsner and dark caramel malts with the addition of debittered roasted malts are most common, but additions of Vienna or Munich malt are also appropriate. Low mineral content water. Traditional Czech hops. Czech lager yeast.

Comparison

The beer is the Czech equivalent of a dark lager ranging in character from Munich Dunkel to Schwarzbier, but typically with greater malt richness and hop aroma, flavor, and bitterness.
