Also known as Berliner Weiße, Berlin white beer.
Pronounced ber-LEEN-er VICE-uh.
Berliner Weisse was Berlin’s everyday beer into the twentieth century, produced by hundreds of breweries. Its acidity comes from Lactobacillus fermenting alongside Saccharomyces, and it is served at a strength — around 3% ABV — that makes it a genuine session drink despite the intensity of the sourness.
The traditional service with a shot of raspberry or woodruff syrup exists to soften the acidity, and remains common in Berlin. Craft interpretations generally serve it unsweetened.
The style was nearly extinct by the 1990s, and much of its revival happened outside Germany.
A good one is bracingly sharp and completely clean, with the acidity reading as lemon rather than as anything dairy or vinegary, and it should finish so dry that the next mouthful is immediate. At 2.8–3.8% it is among the most refreshing beers made. Whether to take the syrup is a genuine choice rather than a beginner's compromise — the traditional service exists for good reason.

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 pale straw |
|---|---|
| Clarity | hazy |
| Head | White, large but short-lived |
| Fermentation | Mixed fermentation. Brewer-selected cultures beyond a single yeast — typically Saccharomyces plus Brettanomyces, Lactobacillus and/or Pediococcus — often over months in wood. |
| Origin | Germany — Berlin |
| Tradition | German regional speciality 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 | 2.8–3.8% ABV |
| IBU | 3–8 IBU |
| Colour | Very pale straw — 2–3 SRM, 4–6 EBC. |
| Original gravity | 1.028–1.032 |
| Final gravity | 1.003–1.006 |
| Carbonation | 3–4 vol CO₂ |
Classified by BJCP-2021 as Berliner Weisse (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, Wheat malt |
|---|---|
| Yeast | Lactobacillus, Saccharomyces cerevisiae, Brettanomyces |
Serving
| Temperature | 4–7°C |
|---|---|
| Glass | Goblet, Wit tumbler |
| Dispense | Bottle conditioned — Beer refermented in the bottle with added yeast and sugar, producing natural carbonation and excellent ageing potential. |
Freshness and storage
Berliner Weisse shows best within 3–12 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.
- Soured during production rather than through a long maturation with a live culture. The acidity itself is stable, but the delicacy around it is not, and keeping the beer does not develop anything new.
What changes with time
- Oxidation. Reaction with oxygen, producing wet cardboard and sherry notes in pale beer and dark-fruit depth in strong dark beer. Months to years, depending on packaged oxygen and temperature.
- 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
- Brown glass bottle — No format-specific concerns beyond the general advice above.
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
- Borscht
Deliberately soured beetroot with soured cream on top: two lactic acidities and an earthy sweetness underneath. A lactic beer agrees with both, where roast against that much acid turns metallic — the same interaction that rules stout out beside pickled herring.
- Fresh cheese
Unaged cheese has nothing but milk fat and a lactic tang, and it is the most easily buried thing in the cheese catalogue. A Berliner Weisse is quiet enough not to bury it and shares the lactic acidity directly, so the two read as the same note twice.
- Dim sum
Bitterness, carbonation and a dry finish scrub the fat off the palate, so each mouthful of food tastes as good as the first.
- Feta
Bitterness, carbonation and a dry finish scrub the fat off the palate, so each mouthful of food tastes as good as the first.
- Goat's cheese
Bitterness, carbonation and a dry finish scrub the fat off the palate, so each mouthful of food tastes as good as the first.
- Guacamole
Tartness resets the palate between mouthfuls, the way a squeeze of lemon does.
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
Gose

Suits you if: You like Berliner Weisse but want less dryness. Reason not to: The main shift is less dryness, which is a small step rather than a change of direction.
Kettle sour
The modern fast-soured equivalent, usually fruited.
Suits you if: You like Berliner Weisse but want less dryness. Reason not to: Noticeably less dryness than Berliner Weisse, which may make it feel thin by comparison.
Lambic
A far more complex and funky spontaneously-fermented sour.
Suits you if: You like Berliner Weisse but want less carbonation. Reason not to: Noticeably less carbonation than Berliner Weisse, which may make it feel thin by comparison.
American wild ale
Same family — both are Sour & wild beers.
Suits you if: You like Berliner Weisse but want more yeast fruitiness (esters). Reason not to: Meaningfully stronger than Berliner Weisse, so it is a different kind of session.
Fruit lambic
Same family — both are Sour & wild beers.
Suits you if: You like Berliner Weisse but want more berry. Reason not to: Noticeably more berry than Berliner Weisse, which not everyone wants.
Compare with
- Berliner Weisse vs Oud Bruin — The main difference is dryness: Berliner Weisse has far more of it than Oud Bruin. Oud Bruin also leads on malt intensity, body and caramel & toffee.
- Berliner Weisse vs Flanders red ale — Berliner Weisse and Flanders red ale 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.
- Berliner Weisse vs Kettle sour — The main difference is dryness: Berliner Weisse has noticeably more of it than Kettle sour. Berliner Weisse also leads on yeast fruitiness (esters); Kettle sour on berry and tropical fruit.
- Berliner Weisse vs Czech pale lager — The main difference is acidity: Berliner Weisse has far more of it than Czech pale lager. Czech pale lager also leads on hop aroma, bitterness and malt intensity.
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.
Infection
These styles are defined by the deliberate use of the same organisms. The difference is entirely control and intent: a brewer who chose the culture, managed the timeline and blended to balance has made lambic; one who did not has made a mistake. There is no way to tell from the organism alone.
Unintended acidity
Lactic acidity is the defining feature of every style listed. It is a fault only where it was not intended — a sour pilsner is broken, a sour gose is correct.
Faults to watch for
- Unintended acidity — Lactic sourness in a style that should not have it — a fault of intent rather than of the organism responsible.
- Infection — Unintended microbial growth — which is a fault only because it was unintended, since the same organisms define lambic.
How it got here
Berliner Weisse was the everyday beer of Berlin, brewed by a large number of the city’s breweries, and it is soured by lactic bacteria fermenting alongside the yeast rather than by wild inoculation.
It fell to almost nothing over the twentieth century — a handful of producers, then effectively none brewing it traditionally — and its current revival has been driven substantially by brewers outside Germany. The practice of serving it with raspberry or woodruff syrup dates from the period of its decline, when the beer was being sweetened to hold a shrinking audience.
1960–2015 Berliner Weisse declines and is reinvented
Berlin’s sour wheat beer nearly disappeared, and the modern revival is largely kettle-soured rather than made by the mixed fermentation of the historical beer.
See the whole sequence on the beer history timeline.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Kettle souring — Sour wort with Lactobacillus before the boil, then boil to kill the bacteria and ferment clean — producing lactic acidity in days rather than years.
- Sour mashing — Acidify wort by holding the mash warm and letting lactic bacteria already present on the grain work before the boil.

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 Infection
Packaged beer is a hostile environment for human foodborne pathogens: the combination of ethanol, a pH typically between about 3.8 and 4.6, hop-derived iso-alpha-acids with antibacterial activity, near-absent oxygen and dissolved carbon dioxide means no such pathogen is known to survive and grow in it.

On Infection
The organisms that do spoil beer — chiefly Lactobacillus, Pediococcus and Brettanomyces — are the same organisms deliberately used to produce sour and mixed-fermentation styles, which is why the identical organism is contamination in one brewery and the product in another.

On Brettanomyces
Brettanomyces is a specific genus routinely pitched as a pure culture, so its presence indicates neither a spontaneous fermentation nor an accident — the common description of it as "wild yeast" conflates the organism with a method.
Backed by a source
Sources: Yeast: The Practical Guide to Beer Fermentation — print; The Oxford Companion to Beer — print
On Brettanomyces
Brettanomyces can consume long-chain carbohydrates that Saccharomyces cannot, which is why a mixed or spontaneous fermentation keeps developing for years after ordinary fermentation would have finished.
Backed by a source

On Lactobacillus
Many Lactobacillus strains are inhibited by hop iso-alpha-acids, which is why kettle souring is performed before the hop addition and why heavily-hopped beer resists lactic spoilage.

On Infection
A compromised package — visible mould at the closure, a pierced or corroded can, a lifted cap or cork — admits organisms the beer’s own chemistry did not exclude, and is the situation in which discarding the beer is the correct response.

On Saccharomyces cerevisiae
Louis Pasteur’s work in the 1860s and 1870s established that fermentation is caused by living microorganisms and that beer spoilage is microbial, which made deliberate control of both possible for the first time.

On Unintended acidity
Lactic acid bacteria spoil beer by acidifying it, by forming haze, and by producing diacetyl — so a contaminated beer often arrives sour, cloudy and buttery together rather than sour alone.
