Czech Lager
Czech lagers share very soft water, Saaz hops, Czech malts, and often decoction mashing, which gives them a rich malt flavor and rounded bitterness. They're ordered by strength and color: the light everyday pale, the premium pilsner-style pale, the amber, and the dark.

How to tell the styles apart
The four Czech lagers line up along two axes: gravity and color. The two pales share a golden hue (3–6 SRM), but Czech Pale Lager (3A) is an everyday beer at 3–4.1%, while Czech Premium Pale Lager (3B), the pilsner, steps up to 4.2–5.8% with the highest bitterness in the family, 30–45 IBU, and a very pronounced Saaz aroma.
Czech Amber Lager (3C) stands out for its amber to copper color (10–16 SRM) and a caramel note you won't find in the pales. Czech Dark Lager (3D) runs from dark brown to nearly black (17–35 SRM), with caramel and soft chocolate- or coffee-like roast. The three stronger ones share the same gravity range, 1.044 to 1.060. All four can show a light touch of diacetyl, which is tolerated in this family.
Brew it yourself
Which one to brew first
If you're going for it, start with Czech Amber Lager (3C) or Czech Dark Lager (3D): caramel and dark malts give you some margin and mask small mistakes. Czech Premium Pale Lager (3B) is the most famous, but it's demanding: it calls for very soft water, fresh Saaz, and a flawless cold fermentation. Czech Pale Lager (3A) looks easy because of its low alcohol, but it's the hardest, because at such low gravity nothing hides the flaws.
Common mistakes
- Using untreated hard tap water. Carbonates and sulfates combined with Saaz give a harsh bitterness; cut it with reverse osmosis or distilled water until it's very soft.
- Using old or poorly stored Saaz. It's a low-alpha hop with a delicate aroma that oxidizes quickly and loses its spicy character; store it vacuum-sealed in the freezer.
- Skimping on malt in the 3A to keep the alcohol low, and ending up with a watery beer. Mash a bit higher or do a decoction to build body at low gravity.
- Cutting the lagering short. Czech lagers are traditionally lagered for weeks or months near 0 °C (32 °F); rush it and the bitterness stays coarse and the beer never rounds out.
How to serve them
Serve at 6–9 °C (43–48 °F), a little warmer than a mass-market lager, so the malt comes through. The pales shine in a thick-walled handled mug or a pilsner glass; the darks, in a mug. They go with Central European food: pork knuckle, sausages, goulash, and aged cheeses; the dark also pairs with roast duck.
