Wheat beer
Weissbier
Bavarian wheat beer defined by its yeast: pronounced banana and clove over a soft, cloudy, highly carbonated body.
- Strength
- 4.3–5.6% ABV
- Bitterness
- 8–15 IBU
- Colour
- Pale straw to deep gold
- Serve at
- 6–9°C
Also known as Hefeweizen, Hefeweissbier, weizen, German wheat beer, wheat beer.
Pronounced VICE-beer.
Weissbier is a yeast-driven beer. The grist is at least half wheat, which gives softness and a lasting head, but the flavour comes from a specialised strain that produces isoamyl acetate — banana — and 4-vinyl guaiacol — clove — in unusually high quantities. Fermentation temperature shifts the balance between the two, which is why examples vary from banana-dominant to clove-dominant.
It is served unfiltered, with the yeast roused into the beer. The traditional pour uses a tall vase-shaped glass, tipped and filled slowly, with the last of the bottle swirled to lift the sediment.
Bavaria protected wheat beer as a royal monopoly for centuries while forbidding it to other brewers, which is a large part of why the style survived in that region and nowhere else.

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 | Pale straw to deep gold |
|---|---|
| Clarity | hazy |
| Head | White, enormous, dense and very persistent |
| Fermentation | Top-fermented (ale). Fermented warm with Saccharomyces cerevisiae, which collects at the surface. Warmer fermentation produces more esters and phenols, so ales tend to carry more fruit and spice from the yeast itself. |
| Origin | Germany — Bavaria (Bavarian; wheat brewing was a ducal privilege from the early seventeenth century until the early nineteenth) |
| 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 | 4.3–5.6% ABV |
| IBU | 8–15 IBU |
| Colour | Pale straw to deep gold — 2–6 SRM, 4–12 EBC. That is a wide range: two examples of this style can look plainly different from each other in the glass. |
| Original gravity | 1.044–1.052 |
| Final gravity | 1.010–1.014 |
| Carbonation | 3–4 vol CO₂ |
| Apparent attenuation | 72–80% |
Classified by BJCP-2021 as Weissbier (exact fit); BREWERS-ASSOCIATION as South German-Style Hefeweizen (close 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 | Wheat malt, Pilsner malt |
|---|---|
| Yeast | Weissbier yeast |
Serving
1. Tilt and pour steadily
Glass at about 45 degrees, bottle to the side of it, poured in one continuous movement. Wheat beer foams readily and a stop-start pour produces a head that is all bubble and no structure.
2. Straighten up and leave a finger behind
Bring the glass upright as it fills and aim for two or three centimetres of head. Stop with roughly a finger of beer still in the bottle — that is where the yeast is.
3. Roll the bottle, then add it
Roll the last of the beer around the base to lift the sediment, and pour it in. The roll comes last because rousing early would mean pouring cloudy beer through a head that has not formed yet. The yeast is part of this style, not an optional extra.
| Temperature | 6–9°C |
|---|---|
| Glass | Weizen glass |
| Dispense | Bottle conditioned — Beer refermented in the bottle with added yeast and sugar, producing natural carbonation and excellent ageing potential. |
Freshness and storage
Weissbier shows best within 1–3 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.
- Changes quickly enough that freshness is the dominant quality variable.
- Bottle-conditioned, so live yeast continues to scavenge oxygen and the beer is more forgiving of time than an equivalent filtered version.
The volatile banana and clove esters fade quickly. A fresh Weissbier is dramatically more expressive than a six-month-old one.
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
- Brown glass bottle — Live yeast in the package continues to scavenge oxygen, which slows staling and builds condition.
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
- Brunch
High carbonation cuts through fried breakfast fat, the wheat body suits eggs, and at 5% it is a defensible thing to drink before noon.
- Chana masala
The sauce is sour and aromatic rather than hot, so the usual advice about keeping bitterness down for curry matters less than finding something to meet the tang. Weissbier has the residual sweetness to sit under the amchur and a clove-like phenol that lines up with the cumin and coriander.
- Jerk chicken
Scotch bonnet heat wants residual sweetness and low bitterness, and banana-clove yeast character sits naturally with allspice.
- Laksa
Coconut, chilli and shrimp paste at once. Wheat beer's sweetness and low bitterness relieve the heat while its body stands up to the richness.
- Shakshuka
The sauce leads rather than the eggs, and it is sharp: reduced tomato with cumin and paprika. Weissbier has the residual sweetness to sit under that acidity and a clove-like phenol that lines up with the spicing, where a dry, bitter beer would turn the tomato metallic.
- Spicy food
Low bitterness, soft wheat body and banana-clove fruit that reads as sweetness on a burning palate. One of the most reliable answers to heat.
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.
- Ayinger Bräuweisse
A Bavarian village weissbier from a brewery better known for its dark lagers, and the fruit-forward end of the style.
- Erdinger Weissbier
The most widely exported Bavarian wheat beer, and for most drinkers outside Germany the first weissbier they meet.
- Paulaner Hefe-Weißbier Naturtrüb
One of the two Bavarian wheat beers a reader outside Germany is most likely to be able to buy, and the more banana-forward of them.
- Schneider Weisse Original
A Bavarian wheat beer from the brewery that kept the style alive when it was out of fashion, and darker than most modern examples.
- Weihenstephaner Hefeweissbier
The reference Bavarian Hefeweizen, with the banana and clove balance the style is defined by.

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.
Chlorophenol
Phenolic character is correct in these styles, but the *kind* of phenol differs. Clove, pepper and smoke are yeast- or malt-derived and belong. Sticking plaster, antiseptic and TCP are chlorophenols and are a fault in every style without exception.
Detectable from roughly 0.000005–0.00002 ppm. Extremely low threshold — parts per trillion.
Chill haze
Several styles are deliberately hazy, and in a New England IPA the haze is engineered from protein, polyphenol and low-flocculating yeast. Chill haze is only a fault where the style calls for brilliant clarity.
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.
- Acetaldehyde — A green-apple note indicating beer served before fermentation finished — the classic sign of a rushed product.
How it got here
Wheat brewing in Bavaria was a ducal monopoly: the ruling house reserved the right to brew it, and the revenue was substantial enough that the privilege was held for roughly two centuries before being released in the early nineteenth.
Freed of the monopoly, the style then nearly died. By the mid-twentieth century wheat beer was a minority taste and several of its breweries had abandoned it. Its recovery from the 1960s onward was rapid and complete enough that it is now among the most-drunk styles in southern Germany, and the clove and banana character produced by its yeast is one of the few genuinely distinctive flavour signatures in brewing.
Common misconceptions
“The banana and clove flavours mean something was added, or the beer has gone wrong.”
Both come from the yeast. Isoamyl acetate produces the banana note and 4-vinyl guaiacol the clove; the strain used for Weissbier generates both in quantity when fermented warm. No fruit or spice is added, and their presence is the style working correctly.
“You should serve it with a slice of lemon.”
Not a Bavarian practice, and it works against the beer: citrus acid knocks down the head that the style is prized for, and the lemon competes with the delicate clove and banana. The garnish convention came from elsewhere and is more common with Belgian witbier, where orange peel is already part of the recipe.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Step mash — Raise the mash through a sequence of held temperatures, each chosen to favour a particular enzyme, for precise control over fermentability and protein.
- 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.
- Top fermentation — Ferment warm with Saccharomyces cerevisiae, producing the ester and phenol character that distinguishes ales from lagers.
- Open fermentation — Ferment in a vessel open to the air, allowing krausen to be skimmed and yeast to be cropped from the surface.
- Bottle conditioning — Carbonate beer through a secondary fermentation inside the sealed bottle, using residual or freshly-added yeast with priming sugar.
Questions
Should you pour Weissbier with the yeast?
Yes, by tradition. Pour most of the bottle slowly into a tilted glass, then swirl the last centimetre or two to lift the settled yeast and add it. The yeast contributes body and much of the aroma. Some drinkers prefer it clear — that is a preference, and Kristallweizen exists precisely for 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 Bottle conditioning
Whether naturally conditioned beer has a perceptibly finer carbonation than force-carbonated beer at the same level is disputed; what is not disputed is that bottle-conditioned beer contains live yeast that continues to scavenge oxygen.
— Widely repeated trade and enthusiast position that secondary fermentation produces smaller, finer bubbles and a softer mouthfeel.
— Carbonation level and dispense conditions determine bubble behaviour, and no controlled work establishes a difference attributable to the carbonation route itself at matched volumes.
BeerHQ separates the contested sensory claim from the uncontested functional one: live yeast measurably slows staling regardless of whether the bubbles differ.
Genuinely contested Credible sources disagree, so both positions are given rather than one.

On Acetaldehyde
Acetaldehyde is a normal intermediate in alcoholic fermentation that yeast converts onward to ethanol, so its presence in finished beer generally indicates the beer left the yeast before fermentation and clean-up were complete.

On Acetaldehyde
Unlike most off-flavours, acetaldehyde is often recoverable: left in contact with healthy yeast at a reasonable temperature, the compound is generally consumed.

On Chill haze
Chill haze consists of complexes between proline-rich proteins and polyphenols that come out of solution when beer is chilled and redissolve as it warms, which is what distinguishes it from permanent haze.

On Chlorophenol
The medicinal, TCP or plastic character of chlorophenols forms when chlorine or chloramine in brewing water reacts with phenolic compounds from malt and hops, and is preventable by treating the water before use.

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.

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.

The banana and clove character of a Bavarian weissbier comes from isoamyl acetate and 4-vinyl guaiacol produced by the yeast strain, not from the wheat, and the balance between them shifts with fermentation temperature.
