Sensory descriptor
Caramelised apple
Burnt-sugar sweetness over cooked fruit, from sugar breaking down under heat or high concentration.
Also called Caramel.

What causes it
Caramelisation is the thermal decomposition of sugars in the absence of the amino acids Maillard chemistry requires, and it yields a family of furans, maltol-type compounds and diacetyl-adjacent diketones that together read as caramel. In cider it arises where sugar is present at high concentration and heat is applied: in the boiling of juice for some traditional and concentrate-based products, in ice cider, and where caramel colouring has been added as a permitted colourant. It also develops slowly in long-aged sweet ciders without any applied heat at all.
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.
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.
Glucose
The sugar yeast takes first and the smallest of the three in apple juice, which is why the last sugar left in a slow ferment is almost never glucose.
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.
Diacetyl
The butter compound, made mainly by lactic acid bacteria and perceptible at very low concentration, which is a defining part of some traditional ciders and an obvious fault in others.
What raises it
Processes that increase this character, or preserve it where it would otherwise be lost.
Ice concentration
Freezing pressed juice and drawing off the unfrozen fraction, so that water is removed as ice and everything else in the juice is left behind more concentrated.
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.
Back-sweetening
Adding sugar, juice or concentrate to a cider that has fermented dry — a straightforward adjustment that leaves the drink microbiologically unstable until something is done about it.
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.
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 Caramelised apple
Caramelised apple is expected in ice cider and pommeau and is one of the notes competition frameworks list for those categories. In a table cider it points at concentrate, at added caramel, or at age.
The overlap with the lactic family is real and confuses panels: caramelisation produces small quantities of diketones chemically related to diacetyl, so a caramel note and a butterscotch note can be adjacent. The distinguishing feature is that diacetyl from malolactic fermentation arrives without any cooked-fruit layer beneath it.
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.
Cooked juice
The flat, jammy, slightly sulphurous character of over-heated juice or concentrate, recorded as a processing fault.
Stewed apple
Soft, wet, low-definition cooked fruit without browning, from prolonged gentle heat or long warm storage.
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.
- 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 do i make my cider sweeter
- 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.
- How is cider pasteurised

The instrument behind the "contains sulphites" declaration and the alcoholic-strength labelling rule. Read on 2026-08-24 in the assimilated text maintained on legislation.gov.uk, which is the version in force for Great Britain and keeps the EU numbering. Two provisions matter to cider and both are widely misquoted: the sulphite threshold is 10 mg/L rather than a percentage, and a labelled cider strength carries a tolerance of a full percentage point either way — twice what still grape wine is allowed.
