Old ale is defined by keeping. Extended maturation develops vinous, sherry-like notes, and traditionally a degree of Brettanomyces or mild acidity was expected rather than treated as a defect — an important distinction, because the same character in a fresh pale beer would be a fault.
The wild and oxidative notes are the hardest thing to read here, because in this style a trace of sherry, leather or gentle acidity is the beer working and a great deal of it is the beer gone. The distinction is integration: developed character sits underneath the malt, while spoilage sits on top of it and reads as sharp or papery. A good old ale tastes older than it is in a way that seems intentional.
In practice the style is rarely found on draught and rarely found fresh, which is consistent with what it is for. Serve it at cellar temperature in a small measure; cold, the dried fruit and treacle close up entirely and what remains reads as thin and faintly sour.

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 | Amber to dark brown |
|---|---|
| Clarity | clear |
| Head | Tan, moderate |
| 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 | United Kingdom |
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 | 5.5–9% ABV |
| IBU | 30–60 IBU |
| Colour | Amber to dark brown — 10–22 SRM, 20–43 EBC. That is a wide range: two examples of this style can look plainly different from each other in the glass. |
| Original gravity | 1.055–1.088 |
| Final gravity | 1.015–1.022 |
| Carbonation | 1–2 vol CO₂ |
Classified by BJCP-2021 as Old Ale (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 | Maris Otter, Crystal malt, Invert sugar |
|---|---|
| Yeast | English ale yeast, Brettanomyces |
Serving
| Temperature | 11–14°C |
|---|---|
| Glass | Tulip glass, Snifter |
| Dispense | Cask, hand-pulled — Beer that completes fermentation in the cask and is drawn by hand pump without added gas, served at cellar temperature.Bottle conditioned — Beer refermented in the bottle with added yeast and sugar, producing natural carbonation and excellent ageing potential. |
Freshness and storage
Old ale is typically at its best 12–60 months after packaging, and time is working for it rather than against it.
Rewards age. Given cool, dark, upright storage this develops depth most drinkers would call an improvement. Buy two and compare.
- BeerHQ records this style as one that develops rather than declines with time.
Brewed to be kept. Develops sherry, leather and dried-fruit notes; some examples carry a deliberate wild character that increases with time.
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.
- Deliberate ageing. Keeping a beer on purpose, accepting some oxidation because of what it develops in return. One to ten years for suitable styles. Most beer is not suitable.
- 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.
- Cask — No light can reach the beer, so lightstrike is impossible in this format. This format admits air by design and assumes the beer will be drunk within days rather than months.
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.
- Robinsons Old Tom
A Stockport strong ale brewed continuously since the nineteenth century, and one of the few English old ales that was never reconstructed.
- Theakston Old Peculier
The reference English old ale — dark, rich, faintly liquorice-tinged — and named for an ecclesiastical peculiar rather than for being odd.
If you like this, try
British strong ale
Same family — both are Strong ale beers.
Suits you if: You like Old ale but want less caramel & toffee. Reason not to: The main shift is less caramel & toffee, which is a small step rather than a change of direction.
English barley wine
A stronger and more intense beer from the same keeping tradition.
Suits you if: You like Old ale but want more sweetness. Reason not to: Meaningfully stronger than Old ale, so it is a different kind of session.
Wee heavy

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.
Oxidation
In strong, malt-dense and deliberately aged beers, controlled oxidation produces sherry, leather and dried-fruit complexity that is the reason to cellar them. The distinction is the character it produces: sherry and dried fruit in a barley wine is development; wet cardboard in a pale ale is staling. Papery notes are a fault in any style.
Faults to watch for
- Acetic acid — Vinegar character produced by acetic acid bacteria, which need oxygen — so it always points to air ingress.
- Fusel alcohol — Harsh, solvent-like alcohol heat from fermentation run too warm or under stress — distinct from the pleasant warmth of a strong beer.
How it got here
"Old" meant matured, in contrast to mild, which meant fresh. Old ale was kept for months or longer, traditionally in wood, where slow oxidation and often a resident Brettanomyces population added the vinous, leathery depth the name still implies. Much of it was blended back into younger beer rather than sold as it was.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Infusion mash — Reach and hold a single conversion temperature by mixing grain with water at a calculated strike temperature, without further heating.
- Cask conditioning — Complete fermentation and carbonation inside the cask the beer will be served from, so it arrives at the drinker alive.
- Bottle conditioning — Carbonate beer through a secondary fermentation inside the sealed bottle, using residual or freshly-added yeast with priming sugar.
- Barrel ageing — Mature beer in wooden barrels for the wood and spirit character they contribute, or for the microflora they harbour and the slow oxygen exchange they allow.

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 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 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.

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.

On Cask conditioning
Cask-conditioned beer completes its fermentation in the container it is served from, retaining live yeast and residual fermentable material, and is dispensed without added carbon dioxide.

On Crystal malt
Crystal malt is produced by stewing wet germinated grain so that starch converts to sugar inside the husk, then kilning so that sugar caramelises in place — which is what distinguishes it from ordinary kilned malt.

On Crystal malt
Crystal malt contributes sugars that brewing yeast largely cannot ferment, which is why it adds residual sweetness and body rather than alcohol.

On Fusel alcohol
Fusel alcohols are a fault only at concentration: at high levels they impart off-flavours, while at low levels they and their esters are an essential part of the flavour and aroma of fermented drinks.

On Fusel alcohol
The higher alcohols behind fusel character are formed by yeast from amino acids through the Ehrlich pathway: the amino acid is transaminated to an alpha-keto acid, which is decarboxylated to an aldehyde and then reduced to the alcohol.

On Tulip glass
An inward-curving rim concentrates volatile aromatics in the headspace above the beer, which is a real and measurable effect and the only glassware mechanism with a straightforward physical basis.

On Acetic acid
Lactic acid reads as clean and yoghurt-like while acetic acid reads as sharp and vinegary, which is why a gose and a Flanders red are both sour but do not taste alike, and why acetic character in a cask ale indicates air ingress rather than intent.

On Oxidation
In strong dark beer the same oxidative chemistry produces sherry, port and dried-fruit character that many drinkers actively seek, which is why oxidation is a defect in a fresh pilsner and part of the appeal of an aged barley wine.

On Oxidation
The wet-cardboard character of stale beer is attributed principally to trans-2-nonenal, a carbonyl formed from lipid precursors and perceptible at extremely low concentrations.
