Pale lager
Czech premium pale lager
The original pale lager: rich bready malt, generous Saaz hopping and a rounded bitterness that soft Bohemian water makes possible.
- Strength
- 4.2–5.8% ABV
- Bitterness
- 30–45 IBU
- Colour
- Deep gold to light amber
- Serve at
- 6–8°C
Also known as Bohemian pilsner, ležák, lezak, Czech pilsner, pilsner urquell style.
Pronounced LEH-zhahk.
Brewed first in Pilsen in 1842, this is the beer every pale lager in the world descends from. What makes it distinct from its descendants is that nothing was taken out: full pilsner malt with no adjuncts, decoction mashing for bready depth, high late-hopping with Saaz, and long cold conditioning.
The bitterness is substantial — often 35–45 IBU, comparable to a modern pale ale — but it reads as soft and rounded rather than sharp. That is the very low mineral content of Pilsen water: the same hopping rate over Burton water would be aggressive.
A well-kept example served from tank, unpasteurised, is a materially different drink from the pasteurised bottled export version of the same brand.
Three things separate this from a German Pils, and all of them are about softness. Pilsen's water is exceptionally low in minerals, which rounds the bitterness rather than sharpening it; decoction mashing, where part of the mash is boiled and returned, builds a deeper bready malt character; and Saaz hops are spicy and floral rather than sharp.
The result should taste fuller and rounder than its strength suggests, with a golden rather than straw colour and a bitterness that is substantial but soft-edged. Served properly from a Czech tank or side-pull tap it also carries a dense, wet foam that is part of the experience rather than decoration.

How it tastes
BeerHQ’s own comparative scale, not a measurement. Each bar is a range because a style is a span of real beers rather than one beer.
Appearance and character
| Colour | Deep gold to light amber |
|---|---|
| Clarity | clear |
| Head | Thick, white, dense and exceptionally persistent |
| Fermentation | Bottom-fermented (lager). Fermented cool with Saccharomyces pastorianus, which settles out, then conditioned cold. The cooler process suppresses yeast-derived fruitiness, leaving malt and hop character exposed. |
| Origin | Czechia — Pilsen (1842) |
| Tradition | Bohemian pale lager brewing |
Measurements
Conventional ranges published by style bodies, not a specification. IBU measures iso-alpha acids in a lab and does not track perceived bitterness — compare it against the sensory scale above rather than reading it as a flavour rating.
| Measurement | Typical range |
|---|---|
| ABV | 4.2–5.8% ABV |
| IBU | 30–45 IBU |
| Colour | Deep gold to light amber — 3.5–6 SRM, 7–12 EBC. |
| Original gravity | 1.044–1.060 |
| Final gravity | 1.013–1.017 |
| Carbonation | 2–3 vol CO₂ |

Freshness and storage
Czech premium pale lager shows best within 2–4 months of packaging. After that it declines in quality rather than becoming unsafe.
Drink fresh. Buy it as young as you can and drink it soon. What makes this beer worth drinking is the first thing to leave it.
- Built on hop aroma, which is the least durable thing in beer. What you are paying for is the first thing to leave.
What changes with time
- Flavour decline. The beer is still perfectly sound, but the most volatile parts of its character have faded. Weeks to a few months, fastest in heavily dry-hopped beer.
- Staling. The general, gradual loss of freshness that affects all beer, accelerated sharply by warmth. Months, and roughly twice as fast for every 10 °C warmer.
- Lightstrike. The skunky note that develops when beer is exposed to light through inadequate packaging. Minutes in direct sun; days to weeks under shop lighting.
In the package
- Aluminium can — No light can reach the beer, so lightstrike is impossible in this format. Very low oxygen ingress, which matters for a beer this dependent on hop aroma.
- Brown glass bottle — No format-specific concerns beyond the general advice above.
- Green glass bottle — Light reaches the beer through this glass. Keep it in the dark, and be wary of bottles that have sat under shop lighting.
- Keg — No light can reach the beer, so lightstrike is impossible in this format. Very low oxygen ingress, which matters for a beer this dependent on hop aroma.
Old beer tastes worse; it does not become dangerous. Ethanol, low pH, hop compounds and the absence of oxygen make packaged beer hostile to the organisms that cause foodborne illness. The exception is a compromised package — visible mould at the closure, a pierced or rusted can, a lifted cap — which is a reason to discard the beer regardless of its age.
Guidance, not an expiry date. How a beer is stored matters more than the date printed on it, and staling roughly doubles in rate for every 10 °C. See storage and freshness for the full model.
What to eat with it
- Pickled herring
Vinegar-cured herring is sharp, saline and oily all at once, and it is drunk with plain pale lager across the whole Baltic for a reason: a beer with its own strong flavour has to argue with the acidity, and a beer without one simply clears it.
- Pizza
Pizza is three problems at once — tomato acidity, cheese fat and a charred base. A well-made pale lager handles all three: bready malt meets the crust, carbonation clears the fat, and the bitterness is soft enough not to fight the tomato.
- Cheese fondue
Melted cheese eaten continuously coats the mouth in a way sliced cheese does not, which is why the traditional accompaniments are all acidic. A crisp lager does the same job with carbonation and a dry finish, and adds no weight to a plate that is already heavy.
- Paella
Saffron rice and seafood need a beer with enough malt to meet the socarrat and enough bitterness to reset between mouthfuls.
- Shellfish
Saaz’s delicate spice suits the sweetness of crustacean meat, and the crisp finish handles the salt without overwhelming a light dish.
- Adobo
Beer and dish carry similar weight, so neither flattens the other.
Beers to try
Widely-known examples BeerHQ carries as reference points for this style. Not a recommendation list and not ranked — these are the beers that make the category concrete.
- Bernard Sváteční ležák
An unpasteurised Czech premium pale lager from an independent brewery, and the useful control in the argument about what changed after 1989.
- Budweiser Budvar
A long-lagered Czech pale lager, softer and rounder than Urquell, and sold under different names in different countries because of a century-old trade mark dispute.
- Pilsner Urquell
The original pale lager, and still the reference: rich Moravian malt, a firm Saaz bitterness and a finish far drier than the sweetness of the malt suggests.
- Staropramen Premium
Prague’s largest-selling lager, and the Czech beer most drinkers outside the country meet on draught.

Characteristics that may be expected here
Each of these is treated as a fault in most beer, and in this style it can be part of the character. Intensity and context decide which: a trace that suits the style and an obvious, dominating version of the same thing are not the same finding. Follow the link where you want to work out which one you have.
Diacetyl
A low level of diacetyl is traditionally tolerated and by some brewers considered characteristic in Czech pale lager, where it adds a rounded, slightly creamy note. German brewing treats the same compound as a straightforward defect. This is a difference of tradition rather than chemistry — and in every other style, obvious butter is a fault.
Detectable from roughly 0.01–0.15 ppm. Threshold varies substantially between individuals; some tasters are effectively blind to it.
Excess sulphur
A faint struck-match note is within style for some fresh German and Czech lagers, and the historical "Burton snatch" was a sulphury note regarded as a mark of authenticity. Rotten egg or drains is a fault anywhere.
Faults to watch for
- Diacetyl — A buttery compound with a very low threshold — normally a sign of rushed fermentation, but traditional at trace levels in some Czech lagers.
- DMS — A cooked-vegetable note from a malt precursor that a vigorous open boil should have driven off.
- Oxidation — The universal ageing fault: oxygen degrades beer into papery, cardboard-like staleness, and dulls everything that made it good.
How it got here
Pilsen’s burghers, dissatisfied enough with the town’s beer to dump it publicly, built a new brewery and hired a Bavarian brewer who brought bottom-fermenting yeast with him. The beer he produced in 1842 was pale, clear and golden at a moment when almost all beer was brown and cloudy.
It could not have been made much earlier. Indirect kilning had only recently made genuinely pale malt possible, and cheap glassware meant drinkers could see the difference for the first time. Within decades it had been imitated everywhere, and most of the beer brewed in the world today is descended from it.
1800–1850 Indirect-fired kilning makes pale malt practical
Drying malt with hot air rather than over an open fire allowed pale, smoke-free malt to be produced at scale.
1842 The first pale bottom-fermented beer is brewed in Plzeň
A Bavarian brewer, exceptionally soft local water, pale kilned Moravian malt and Saaz hops produced a beer that reshaped world brewing within a generation.

Common misconceptions
“Pilsner and lager are different things.”
Pilsner is a type of lager — specifically a pale, hop-forward one. All pilsners are lagers; most lagers are not pilsners. The word became a generic term for pale lager in many markets, which is why supermarket "pilsner" often bears little resemblance to the Bohemian original.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Decoction mash — Raise a mash to its next temperature step by removing part of it, boiling that portion and returning it — the traditional continental method.
- Diacetyl rest — Raise a fermentation’s temperature near its end so the yeast reabsorbs and reduces the diacetyl it produced earlier.
- Lagering — Store beer cold for an extended period after fermentation to clarify it and produce the clean, rounded character lagers are named for.
Questions
What is the difference between Czech and German pilsner?
Czech versions are fuller-bodied, slightly sweeter and more golden, with a rounded bitterness and a bready malt depth from decoction mashing. German Pils is paler, drier, lighter in body and more sharply bitter, with a crisper finish. The water explains much of it: soft Bohemian water rounds bitterness, while harder German water sharpens it.

Evidence
What BeerHQ knows about this, and how. Every statement carries the state of the evidence behind it rather than being presented flatly as fact.
On Decoction mash
Whether decoction mashing produces a malt character that a well-executed step mash with modern malt cannot is genuinely disputed within the trade.
— Many traditional brewers and a substantial body of brewing literature hold that boiling part of the mash develops melanoidin character that cannot be reproduced otherwise.
— Several breweries historically associated with decoction have moved to step mashing without their beers being widely reported as diminished, and blind comparisons have not established a consistent difference.
The practical justifications for decoction — hitting temperature steps without a thermometer, working with undermodified malt — have both disappeared. What remains contested is whether the flavour justification stands alone.
Genuinely contested Credible sources disagree, so both positions are given rather than one.

On Bohemian pale lager brewing
Bohemian pale lager combined exceptionally soft local water, Moravian pale malt and Saaz hops, a combination that suited a very pale beer in a way most European water of the period did not.

On Diacetyl
The buttery or butterscotch character described as diacetyl is 2,3-butanedione, a vicinal diketone formed outside the yeast cell by oxidative decarboxylation of alpha-acetolactate.

On Diacetyl
A low level of diacetyl is traditional and accepted in some Czech pale lagers and in some Yorkshire and Scottish ales, where it contributes a rounded buttery softness the brewers are not attempting to remove.

On Diacetyl rest
Raising a fermentation to 16–20 °C near its end accelerates yeast reuptake and reduction of diacetyl, which is slow at lager fermentation temperatures and is interrupted entirely if the beer is crashed cold too early.

On Diacetyl
Diacetyl reaches beer by two unrelated routes: as a normal fermentation by-product that healthy yeast subsequently reabsorbs, or from bacterial contamination — chiefly Pediococcus — which produces it continuously and cannot be rested out.

On DMS
A low level of DMS is accepted, and by some tasters expected, in pale lagers built on pilsner malt, and only reads as a defect when it dominates.

On DMS
Dimethyl sulphide is generated during wort heating from S-methylmethionine, a precursor formed during germination and progressively destroyed by kilning — which is why it is highest in lightly-kilned pilsner malt and negligible in darker malts.

On DMS
DMS is volatile and leaves wort as vapour during a vigorous uncovered boil, which is why covering the kettle, boiling gently or cooling the wort slowly all raise the level in finished beer.

On Excess sulphur
Sulphur compounds are produced in quantity during cold lager fermentation and are normal at that stage, dissipating during lagering; their presence in a young lager is expected rather than defective.
