Also known as black lager, Schwarz.
Pronounced SHVARTS-beer.
Schwarzbier is the clearest demonstration that colour and body are unrelated. It is nearly black and it is a lager — bottom-fermented, cold-matured, light in body, dry in finish — with a roast character that reads as bitter chocolate and coffee rather than as the acrid burnt note of a stout. At 4.4–5.4% it is a session beer that happens to look like a strong one.
That combination makes it the single most useful recommendation in the catalogue for a Guinness drinker who wants something different without leaving familiar ground: the roast is recognisable, the body is lighter, and the lager fermentation removes the fruit character entirely. Judge it against Munich Dunkel rather than against stout.

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 | Very dark brown to black, ruby highlights |
|---|---|
| Clarity | clear |
| Head | Tan, creamy, 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 | Germany |
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 | 4.4–5.4% ABV |
| IBU | 20–30 IBU |
| Colour | Very dark brown to black, ruby highlights — 17–30 SRM, 33–59 EBC. |
| Original gravity | 1.046–1.052 |
| Final gravity | 1.010–1.016 |
| Carbonation | 2–3 vol CO₂ |
Classified by BJCP-2021 as Schwarzbier (exact fit). BeerHQ maintains its own taxonomy and records how it maps onto others rather than adopting any one of them.

Freshness and storage
Schwarzbier shows best within 4–9 months of packaging. After that it declines in quality rather than becoming unsafe.
No benefit from keeping. Sound for its window and then slowly less good. Nothing bad will happen quickly, but nothing good happens either.
- Sound well past its window, but nothing in it improves with keeping. Drink it while it is fresh.
What changes with time
- 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.
In the package
- Aluminium can — No light can reach the beer, so lightstrike is impossible in this format.
- Brown glass bottle — No format-specific concerns beyond the general advice above.
- Keg — No light can reach the beer, so lightstrike is impossible in this format.
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.

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.
If you like this, try
Munich Dunkel
Softer and sweeter, with less roast bite.
Suits you if: You like Schwarzbier but want more bread & biscuit. Reason not to: Noticeably more bread & biscuit than Schwarzbier, which not everyone wants.
Czech dark lager
A near neighbour, generally sweeter and less roast-driven.
Suits you if: You like Schwarzbier but want less dryness. Reason not to: Noticeably less dryness than Schwarzbier, which may make it feel thin by comparison.
Vienna lager
Same family — both are Amber & dark lager beers.
Suits you if: You like Schwarzbier but want more bread & biscuit. Reason not to: The main shift is more bread & biscuit, which is a small step rather than a change of direction.
International amber lager
Same family — both are Amber & dark lager beers.
Suits you if: You like Schwarzbier but want less malt intensity. Reason not to: The main shift is less malt intensity, which is a small step rather than a change of direction.
Dry stout
A comparable dry roast character, reached with ale yeast and a fuller body.
Suits you if: You like Schwarzbier but want less carbonation. Reason not to: The main shift is less carbonation, which is a small step rather than a change of direction.
Compare with
- Schwarzbier vs Czech dark lager — The main difference is dryness: Schwarzbier has far more of it than Czech dark lager. Schwarzbier also leads on bread & biscuit; Czech dark lager on caramel & toffee and sweetness.
- Schwarzbier vs Munich Dunkel — The main difference is caramel & toffee: Munich Dunkel has noticeably more of it than Schwarzbier. Schwarzbier also leads on coffee; Munich Dunkel on bread & biscuit and nutty.
- Schwarzbier vs Czech amber lager — The main difference is roast: Schwarzbier has noticeably more of it than Czech amber lager. Schwarzbier also leads on dryness and chocolate & cocoa; Czech amber lager on caramel & toffee.
- Schwarzbier vs Vienna lager — Schwarzbier and Vienna lager are closer than the comparison suggests. The measurable differences are small — caramel & toffee is the largest of them — so tradition, strength and what each is brewed for will tell you more than the flavour axes do.
Faults to watch for
- Astringency — A drying, tannic harshness from over-extracted grain husk — the classic sign of sparging too hot, too long or at too high a pH.
- Diacetyl — A buttery compound with a very low threshold — normally a sign of rushed fermentation, but traditional at trace levels in some Czech lagers.
How it got here
Schwarzbier belongs to Thuringia and Saxony rather than to Bavaria, and the distinction matters: it is drier and more sharply roasted than Munich Dunkel, with the roast character coming through cleanly rather than being folded into malt sweetness. Brewing at its historic centre is documented over several centuries, and the style continued through the East German period when much else did not.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Roasting — Take malt or raw grain to high temperature in a rotating drum to produce the deep colours and roast flavours of porter, stout and dark lager.
- 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.
- Bottom fermentation — Ferment cool with Saccharomyces pastorianus, suppressing yeast-derived fruit and spice so malt and hop character stand exposed.
- 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
Is Schwarzbier a stout?
No. It is a lager — cold-fermented and cold-conditioned — while stout is warm-fermented ale. They can look nearly identical in the glass. The Schwarzbier will taste cleaner and lighter, with the roast character smoother and less sharp than a dry stout’s.

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 Astringency
Astringency is a tactile sensation caused by polyphenols binding salivary proteins, and is distinct from bitterness, which is a taste detected by chemoreceptors rather than felt.

On Astringency
Tannin extraction from grain husks rises sharply when sparge water is too hot, too alkaline or continued to very low runnings gravity, which is why brewers stop sparging at a target gravity rather than rinsing the bed dry.

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
Diacetyl has one of the lowest flavour thresholds of any beer compound, detectable by many tasters at concentrations in the region of 0.1 mg/L or below, with substantial variation between individuals.

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.
Backed by a source
Sources: Tasting Beer (2nd edition) — print; The Oxford Companion to Beer — print
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.
Backed by a source
Sources: Yeast: The Practical Guide to Beer Fermentation — print; Technology Brewing and Malting — print
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 Lagering
Carl von Linde’s mechanical refrigeration, first installed in a brewery in the early 1870s, freed lager production from dependence on natural ice and cold cellars.
