Also known as Wiesn, Oktoberfest beer, Wiesnbier.
Festbier is the beer that replaced Märzen at Oktoberfest, and the substitution tells you what it is for. The Munich tents moved to a paler, lighter-bodied, more attenuated beer in the 1970s because drinkers were being asked to sit with it for hours — Märzen's fuller malt sweetness is excellent for one litre and heavy going for three.
So expect a beer that reads maltier than a Helles and drier than a Märzen, gold rather than amber, at 5.8–6.3%. The strength is real and deliberately unobtrusive, which is the style's central skill and the reason it is easy to underestimate.
This is a frequent source of confusion. The amber Märzen that most of the world calls "Oktoberfest beer" has not been the beer poured at the Munich festival for decades; the tents serve a paler, more golden, slightly drier beer. Both names are in use commercially, which does not help.

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 |
|---|---|
| Clarity | brilliant |
| Head | White, dense, 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 — Munich (From the 1970s, replacing Märzen at the Munich festival) |
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 | 5.8–6.4% ABV |
| IBU | 18–25 IBU |
| Colour | Deep gold — 4–7 SRM, 8–14 EBC. |
| Original gravity | 1.054–1.057 |
| Final gravity | 1.010–1.012 |
| Carbonation | 2–3 vol CO₂ |
Classified by BJCP-2021 as Festbier (exact fit). BeerHQ maintains its own taxonomy and records how it maps onto others rather than adopting any one of them.
What goes into it
| Malt | Pilsner malt, Munich malt, Vienna malt |

| Yeast | German lager yeast |
Serving
| Temperature | 6–9°C |

| Glass | Stein, Willi Becher |
| Dispense | Cask, gravity-dispensed — Cask beer poured straight from the tap under gravity, with nothing between the cask and the glass.Keg, CO₂ dispense — Filtered or unfiltered beer force-carbonated and dispensed under CO₂ pressure — the standard modern draught format. |
Freshness and storage
Festbier shows best within 4–8 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.
- 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.
- 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.
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.

Faults to watch for
How it got here
Festbier is what Munich’s Oktoberfest actually serves, and it is not Märzen. The amber, maltier Märzen was progressively replaced from the 1970s by a paler, lighter-bodied beer better suited to being drunk in litre measures, and the amber style now survives mainly in the export market and in American interpretations of the festival.
Common misconceptions
“Oktoberfest beer is the amber Märzen sold under that name.”
Not since the 1970s. The Munich festival tents pour a pale golden Festbier. Amber Märzen remains a real and excellent style, and is what most American "Oktoberfest" beers imitate, but it is no longer the beer at Oktoberfest.
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.

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 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.
Backed by a source
Sources: Beer: Tap into the Art and Science of Brewing — print; Technology Brewing and Malting — print
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.

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 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.
Backed by a source
Sources: BJCP Beer Style Guidelines (2021); Tasting Beer (2nd edition) — print
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.
Backed by a source
Sources: Brewing: Science and Practice — print; Technology Brewing and Malting — print
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 Pale lager
Lager denotes a fermentation and maturation process — cool fermentation with S. pastorianus followed by cold storage — rather than a colour, strength or flavour, which is why Schwarzbier, Rauchbier and Doppelbock are all lagers.

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.
