Sensory descriptor
Stewed apple
Soft, wet, low-definition cooked fruit without browning, from prolonged gentle heat or long warm storage.
- Aroma family
- Cooked and baked apple
- Does it indicate a fault?
- It depends on the style it is met in
What causes it
Stewed character is the result of enough heat, for long enough, to destroy fresh volatiles without reaching the temperatures at which Maillard browning and caramelisation become significant. Pectin depolymerises, cell structure collapses, and the aroma flattens into a soft, damp, slightly flat fruit note. In cider the commonest routes are a long hold at pasteurisation temperature rather than a short flash, and storage of packaged cider at warm ambient temperature over months, which achieves the same chemistry slowly.
A hint of stewed fruit is unremarkable in any heat-treated cider. Where it dominates and the fresh layer is entirely gone, it is the sensory definition of the cooked-character fault.
The compounds responsible
Where the molecule is established. Some descriptors in this lexicon name a compound the compound register does not yet hold a record for; those are named in the cause above instead.
Pectin
The structural polysaccharide of fruit cell walls, which decides how much juice a press releases, whether a cider ever clears, and whether keeving is possible at all.
Hexanal
The green-apple aldehyde generated within seconds of breaking fruit tissue, which gives fresh juice its cut-grass smell and is largely converted away by the yeast.
Fructose
The dominant sugar of apple juice and the sweetest of the common sugars, which is why apple juice tastes sweeter than its total sugar figure implies and why a stuck ferment leaves sweetness behind.
What raises it
Processes that increase this character, or preserve it where it would otherwise be lost.
Pasteurisation
Heating cider enough to inactivate the organisms that would spoil it, either in the sealed package or in-line before filling, at a measurable cost in fresh aroma.
Juice pasteurisation
Heat treatment of juice before fermentation, which inactivates enzymes and microorganisms, and in doing so removes the wild flora that would otherwise ferment it.
Cellar storage
Holding packaged cider in conditions that let it change slowly and predictably, where stability of temperature matters more than the temperature itself.
Shelf-life management
Establishing how long a cider stays acceptable in its package and setting a durability date that reflects evidence rather than convention.
The fault it points at
Meeting this descriptor above a certain intensity is how the fault below is usually noticed first.
Fault
A stewed-apple, caramel or jam-like character from heat applied to juice or cider, most often through pasteurisation or hot storage.
About Stewed apple
Stewed apple is the descriptor most often reached for by judges assessing a cider that has been badly stored rather than badly made, and separating the two is one of the more useful things a competition sheet can do. Heat damage in transit or on a warm shelf produces it in a product that left the cellar sound.
It differs from baked apple by the absence of browning notes and from oxidation by the absence of acetaldehyde and nuttiness. A stewed cider smells cooked and wet; an oxidised one smells aged and dry.
Others in the cooked and baked apple family
Apple pie, stewed fruit, apple sauce, caramelised apple.
Cooked apple
The soft, sweet, aldehyde-stripped apple character of heated fruit or heated juice, the base note of the whole cooked family.
Apple pie
Cooked apple carrying a spice layer — clove, cinnamon or nutmeg — from added spice, from wood, or from yeast-derived vinylguaiacol.
Baked apple
Cooked apple with a browned, Maillard-derived layer over it, met in ice cider and in long-matured sweet styles.
Caramelised apple
Burnt-sugar sweetness over cooked fruit, from sugar breaking down under heat or high concentration.
Cooked juice
The flat, jammy, slightly sulphurous character of over-heated juice or concentrate, recorded as a processing fault.
Toffee apple
Dense Maillard character — butter, brown sugar, slight roast — over concentrated apple, characteristic of ice cider and pommeau.
Apple sauce
Cooked culinary-apple character with the sharpness retained, met where high-acid fruit has been heat-treated.
What people ask next
Questions readers ask about the things this page mentions. Each one goes to the section that answers it rather than to a page written to receive the question.
- How long does cider last — An unopened commercial cider is usually at its finest within a year of packaging, and filtered, pasteurised products carry a stated date. Strong, tannic, bottle-conditioned ciders can improve for several years.
- How should i store cider — Cool, dark and at a steady temperature. Light causes light-strike in clear glass, warmth accelerates oxidation, and temperature swings push cider past the closure of a bottle that is not tightly sealed.
- What does pectin do in cider — Pectin is the structural polysaccharide that holds fruit cells together. In juice it holds haze in suspension, and it is the molecule keeving depends on: strip its methyl groups and it will gel with calcium and float the nutrients out of the juice.
- Which sugar is most of the sugar in apple juice — Fructose, by a long way. Apple juice carries roughly twice as much fructose as glucose, with a smaller amount of sucrose, and fructose is the sweetest of the three on the tongue.
- How is cider pasteurised
- Will pasteurised apple juice ferment — Not on its own — pasteurisation kills the wild yeast — but it ferments readily once a cultured yeast is pitched.

Searched again on 2026-08-25 and it remains the one printed source here that a bibliographic check cannot fix, because it is not a published work with an edition. It is course material issued to participants of a training programme, so there is no catalogue record to verify, no ISBN, and no lawful public copy. Its state stays `registered` for that reason rather than through inattention.

BJCP Beer Style Guidelines — cider and perry categories
Beer Judge Certification Program · classification framework · retrieved 2026-08-24
Opened on 2026-08-24, and the edition matters. CiderHQ registered the 2015 cider guidelines; BJCP has since published a 2025 cider edition, and the old URL now redirects into the current guidelines index. A competition style guide is a dated framework rather than a standing definition, and citing the wrong edition of one is the same class of error as citing a superseded specification. CiderHQ treats BJCP as one competition framework among several and never as the universal cider taxonomy.
