Sensory descriptor
Candied peel
Sweet, concentrated citrus-and-sugar character from terpene release during long maturation of a sweet cider.
Also called Mixed peel, Marmalade.
- Aroma family
- Honeyed
- Does it indicate a fault?
- No — a normal part of cider and perry aroma
What causes it
During extended maturation, glycosidically bound terpene alcohols in the drink hydrolyse slowly under its own acidity and are released as free aroma compounds. Where this happens in a cider carrying substantial residual sugar, the combination of released terpenes with sweetness and with early Maillard products reads as candied peel or marmalade rather than as fresh citrus. It is a slow process, measured in years rather than months, and it is one of the reasons sweet ciders change character in bottle more visibly than dry ones.
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.
Terpenes
The floral and citrus aroma compounds that apples carry only in traces and that hops, spices and botanicals bring in quantity, which is why a hopped cider smells so different from an unhopped one.
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.
Furfural
A toast-and-almond aldehyde formed whenever sugars are heated, arriving in cider either from a toasted barrel or from heat treatment, and a reliable marker of cooked character.
What raises it
Processes that increase this character, or preserve it where it would otherwise be lost.
Bottle maturation
What happens to a cider after it is sealed in glass — which for most ciders is slow decline rather than improvement, and saying so is more useful than implying otherwise.
Oxidative maturation
Ageing a cider with a deliberate, measured oxygen supply so that tannins polymerise and soften and an aldehydic character develops on purpose, which is not the same thing as the oxidation fault.
Barrel ageing
Holding cider in wood — which may mean an old neutral vat used simply as a vessel, or fresh or spirit-seasoned oak used as a source of flavour, and the two are not the same operation.
Cellar storage
Holding packaged cider in conditions that let it change slowly and predictably, where stability of temperature matters more than the temperature itself.
Where it is usually met
Fruit and styles this character is recorded in. A record here is where the descriptor is commonly found, not a claim that every example shows it.
About Candied peel
Candied peel is a long-ageing descriptor for sweet styles and is met most in ice cider and pommeau with several years behind them. Its appearance in a dry cider is unlikely to be well founded, since the sugar component of the perception is missing.
It sits alongside orange peel from the citrus family, and the difference is sweetness and concentration: the same released terpenes read fresh in a dry cider and candied in a sweet one.
Others in the honeyed family
Honey, beeswax, nectar.
Honey
A sweet, waxy floral note from phenylacetaldehyde, formed by mild oxidation of 2-phenylethanol as cider ages.
Beeswax
A dry, waxy, faintly sweet note from long-chain fatty acids and their esters, associated with lees contact.
Honeycomb
Honey with a caramelised, slightly burnt-sugar edge, met where oxidative honey notes coincide with Maillard character.
Nectar
A light, sweet, floral-sugary impression from phenylethyl acetate and residual sugar together.
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.
- Does cider get better with age — Some does. Tannic, dry, bottle-conditioned ciders and ice ciders can gain for several years. Light, fruit-driven and commercially filtered ciders lose their aroma and do not gain anything in exchange.
- 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 is ice cider — Ice cider is made by concentrating apple juice by freezing before fermentation, so that the ferment starts from a very high sugar level and stops sweet. It is a Quebec speciality with a protected definition there.
- What is sweet cider in america — In the United States and Canada, sweet cider means fresh, unfermented, usually unfiltered apple juice, with no alcohol in it. In Britain the same phrase means a fermented cider with residual sugar.
- 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.
- Should i ferment cider in an oak barrel — A sound, full barrel is a fine maturation vessel; a leaky, half-empty or previously spoiled one is the fastest route to vinegar. Wood cannot be sterilised, so a barrel carries whatever lived in it before.

The Science of Cidermaking and associated technical writing
Andrew Lea · reference work · passage verified 2026-08-24
Written by a food chemist who worked at Long Ashton on apple phenolics. Unusual among specialist cider writing in that it is primary-research-adjacent: the author is describing work he did, and cites the literature. This is why it is registered at tier 1 for chemistry while a general cider book is not.

The Cidre Pays d’Auge cahier des charges was read in full on 2026-08-24, in the version homologated by arrêté of 17 January 2026 and published in the Journal officiel on 21 January. That qualification is not decoration. A revision adopted by the Comité national on 10 September 2025 is currently under the procédure nationale d’opposition, is clearly marked as not prejudging the final text, and specifies carbonation differently from the text in force — as grams of CO2 per litre rather than as a minimum pressure in bar. A summary citing the draft would have put a figure on the page that no producer is held to. CiderHQ records the operative text and says which one it is.
