Czech-Style Dark Lager

The dark end of the Czech lager family — tmavé, the deepest of the Czech color tiers.

Also known as Czech Black Lager, Czech Dark Lager, Tmavé, Tmavé Pivo, Tmavý, Tmavý Ležák

The dark end of the Czech lager family — tmavé, the deepest of the Czech color tiers. A reddish-brown to nearly black lager with a rich, slightly sweet malt character spanning bread, toast, caramel, and chocolate, with light roast allowed but never dominant. Bitterness stays low and noble. Typically 4.4–5.8% ABV.

In the glass

Appearance
Reddish brown to black, clear (when color allows it to be perceived), with no chill haze.
Aroma
Medium to medium-high, with a slightly sweet, rich, complex malt character — crystal malt, bread and toast, caramel, and chocolate. Hop aroma is very low to low and noble in character.
Flavor
Rich and malt-driven, with caramel, toast, bread, and chocolate notes. Light roast may appear at moderate levels but should not dominate. Bitterness ranges low to medium-high. A low level of butter-toffee diacetyl is sometimes present and considered acceptable. Many versions show the malt depth typical of decoction mashing.
Mouthfeel
Medium to medium-high body, medium carbonation.

Origin

In the Czech system of classifying beer by color, tmavé (“dark”) is the deepest tier, below světlé (pale) and polotmavé (half-dark). Czech brewers were making dark lagers long before the pale lager revolution of 1842, and the tradition has persisted continuously, most visibly at Prague brewpubs such as U Fleků, which has brewed on the same site since 1499 and built its name on a single dark lager poured there for generations. It is the Bohemian relative of the Bavarian dunkel — sometimes a touch sweeter — and is built the same way the rest of the Czech family is, with extended cold lagering, decoction mashing, and a malt-led balance that keeps roast in check rather than letting it run toward the coffee-like character of a stout or schwarzbier.

Notes

Czech dark lager is dark but rarely roasty in the way a stout is. The emphasis is on complex sweet malt — caramel, toast, bread, a little chocolate — with roast kept to a supporting role. It is the dark counterpart to the famous Czech pale lager and the natural next step beyond the amber polotmavé: same yeast, same lagering, same hops, just taken all the way down the color scale. The best-known examples are draft house beers at Prague brewpubs, though a few packaged versions ship internationally.
