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
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.
