Quebec regulates cidre de glace as a reserved designation with rules on concentration method, minimum sugar and prohibition of added sugar or artificial freezing of the juice. Producers outside Quebec may make the same product but are not bound by those rules, so the term is regulated in one jurisdiction and descriptive elsewhere.
What makes it this style
- The sugar concentration is achieved by freezing — either by pressing frozen fruit, or by freezing juice and drawing off the unfrozen sugar-rich fraction — and not by heat, vacuum or added sugar.
- The concentrated juice enters fermentation at a gravity far above ordinary cider, and the ferment is slow and cold.
- Fermentation is stopped, or stops itself, leaving a large residual sugar; the finished drink is sweet by design.
- Acid is high enough to balance that sugar, which is why cold-climate high-acid fruit is used.
What varies inside the category
Every style covers a range. This is what legitimately differs between two examples that are both correctly called by this name.
- The concentration route. Cryoextraction presses fruit frozen on the tree or in store; cryoconcentration freezes pressed juice and separates the fractions. The two give different aromatic profiles.
- Whether the freezing is natural or mechanical, which the Quebec rules treat as significant and other jurisdictions do not.
- Final residual sugar and alcohol, which trade off against each other along the same curve.
- Cultivar choice, though almost all of it is high-acid dessert fruit rather than tannic cider fruit.
- Ageing, from a few months to several years, over which oxidative and caramelised notes develop.

About Ice cider
Ice cider is a genuinely recent invention with a precise origin in the orchards of Quebec in the late twentieth century, developed by analogy with ice wine but resting on a different fruit and a colder climate. It is the rare case in this ontology of a style that can be dated, and its rapid adoption in Vermont, New England, and parts of Europe has happened within a single generation of makers.
The physics is straightforward and is the whole method. Water freezes at a higher temperature than a sugar solution, so when apple juice is cooled below zero, ice crystals of nearly pure water form and the remaining liquid becomes progressively more concentrated in sugar, acid and everything else dissolved in it. Draw off that liquid and you have a juice two to three times more concentrated than the fruit gave. The alternative route lets whole fruit freeze — left on the tree into winter, or picked in autumn and left outside in the cold — and presses it frozen, so that the ice stays behind in the press.
What follows is a difficult fermentation. Yeast in a high-osmotic-pressure environment works slowly and is stressed, and the ferment can run for months at low temperature before the rising alcohol brings it to a halt — often before the maker has to intervene. The result carries both a great deal of sugar and a substantial alcohol, and it is the acid that makes it drinkable. Concentrating the juice concentrated the malic acid too, and that acid cuts through the sugar in a way that a low-acid fruit could not.
In the glass the drink is dense and viscous, deep gold to amber, with concentrated cooked and dried apple, marmalade and honey notes and a long, acid-driven finish. It is not tannic: cold-climate dessert cultivars supply almost no phenolic structure, and the architecture is sugar against acid rather than sugar against bitterness. That distinguishes it from a keeved cidre doux, which reaches sweetness by an entirely different route and holds it up with tannin instead.
The regulatory position deserves care. Quebec’s reserved designation sets out what may be called cidre de glace within Quebec, including the requirement that concentration comes from cold and not from added sugar or thermal methods. That protection does not travel. A bottle labelled ice cider made elsewhere may follow the same discipline entirely, or may not, and no international body checks.
How much juice a bottle of ice cider takes
Freezing does not add anything; it removes water. So the arithmetic is a mass balance on the dissolved solids, and it can be done before a single apple is frozen. If ice were pure water and every drop of concentrate could be recovered, a juice at 12 °Brix — close to the median of the apple juices measured on this site — would have to lose three fifths of its mass to reach 30 °Brix.
Real separation is worse than that, and always in the same direction. Ice crystals trap sugary liquid between them, the first runnings are the richest and the last are barely sweeter than the juice, and a maker who wants to reach the threshold has to leave some sugar behind in the ice. The figures below are therefore the floor on how much juice a litre of concentrate costs, not an estimate of it.
| Concentrate reached | Gravity of the concentrate | Share of the juice’s mass kept | Litres of juice per litre of concentrate, at least |
|---|---|---|---|
| 25 °Brix | About 1.106 | 48% | 2.2 |
| 30 °Brix — the minimum in Quebec’s cider regulation | About 1.129 | 40% | 2.7 |
| 32 °Brix | About 1.139 | 38% | 2.9 |
| 35 °Brix | About 1.154 | 34% | 3.2 |
| 40 °Brix | About 1.179 | 30% | 3.8 |

Where the ferment has to stop
An ice cider ends sweet because the fermentation stops with most of the sugar unconsumed, and the point at which it stops decides both numbers on the label at once. Every gram of sugar fermented becomes alcohol rather than sweetness, so strength and residual sugar are two readings of one event.
Working through the arithmetic shows why the three figures in Quebec’s cider regulation — at least 30 °Brix in the must, at least 130 g/L of sugar left, and over 7% and up to 13% alcohol — describe a narrow window rather than three independent rules. A must at exactly 30 °Brix cannot reach 13%: by the time it has made a little over 10%, it has reached the residual-sugar floor. A must at 35 °Brix has the opposite constraint, and has to be stopped at 13% with more sugar left than the floor requires.
| Must before fermentation | Fermentable sugar, about | Alcohol when the sugar falls to 130 g/L | Sugar left if stopped at 7% | Sugar left if stopped at 13% |
|---|---|---|---|---|
| 30 °Brix | 305 g/L | About 10% | About 185 g/L | Not reachable without falling below 130 g/L |
| 32 °Brix | 330 g/L | About 11.5% | About 210 g/L | Not reachable without falling below 130 g/L |
| 35 °Brix | 365 g/L | About 13.5% — past the ceiling | About 245 g/L | About 145 g/L |
| 40 °Brix | 425 g/L | About 17% — far past the ceiling | About 305 g/L | About 205 g/L |
Tasting it
What to attend to here specifically, and what is routinely misread. The second list is the more useful one.
What to look for
- Concentration across everything, not only sugar. Freezing removes water, so acid, phenolics and aroma are concentrated in the same proportion — which is why a good ice cider is not merely sweet.
- Acid, which is what keeps it from being syrup. This is the single most important structural element in the category.
- Whether it tastes of apple or of caramel. Long, slow fermentation at high sugar produces a characteristic profile that can drift towards the second.
What gets misread
- Assuming the sweetness was added. It is the juice’s own sugar, concentrated by removing water and left behind when the ferment stopped.
- Reading the low alcohol relative to the sweetness as a fault. The ferment stops because the yeast reaches its limit in a very high-sugar medium, and that is how the sugar survives.
Cold, in a small glass. It is a concentrated drink and the serving sizes reflect that.
What it is mistaken for, and how to tell
One observation per pair, chosen because it separates them. Several of these are not styles at all — a commercial term, a legal category, or a fault wearing the same description.
- Pommeau — Whether it fermented. Ice cider did; pommeau did not, and its alcohol came from a bottle of calvados.
- Cidre de glace — A protected Quebec designation with specific rules on concentration method and residual sugar, rather than a general category.
- A cider made from concentrate — Direction and purpose. Ice cider concentrates the juice to make a richer drink; commodity concentrate is reconstituted with water before fermenting.
How it is made
The methods that define or commonly produce this style.
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.
Cryoextraction
Milling and pressing fruit that has frozen on the tree or in store, so the ice stays behind in the pomace and only concentrated juice runs from the press.
Fermentation temperature control
Managing the temperature at which a ferment runs, which sets not only how fast it goes but which aromatics survive it and what the finished cider tastes of.
Arrested fermentation
Deliberately halting a ferment while sugar remains, to obtain natural sweetness from the fruit rather than from an addition — and accepting the instability that follows.
Cold stabilisation
Holding cider cold before packaging so that anything which would fall out of solution in a cold warehouse falls out in the tank instead.
Sterile filtration
Membrane filtration at a rating that retains viable yeast and bacteria, which is what allows a sweet cider to be shelf-stable without heat or preservative — provided the filling that follows is aseptic.

Where it is made
Food
Interactions rather than suggestions. Each explains the mechanism, so you can extend it to a dish that is not listed.
- Apple pie — The most direct aroma bridge available: cryoconcentration produces exactly the cooked-apple and caramelised-fruit volatiles that baking produces, and the sugar level clears the dessert’s own sweetness so the cider is not exposed as sour.
- Stilton — Blue cheese is the clearest case in this file for sweet–salt suppression: very high salt is markedly reduced by high residual sugar, and the acid retained through cryoconcentration keeps the cider from reading as syrup. Both sides are intense enough to be heard.
- Apple crumble — Cooking apples keep more acidity than dessert varieties, so the dish is sweet and sharp at once; ice cider is one of the few things that is both, and the fruit is the same fruit.
- Caramel — Concentration and heat treatment generate caramelised sugar aromatics in the cider itself, so the aroma bridge is direct; the sugar level meets the caramel’s and the acid keeps the pairing from being purely sweet.
- Cheesecake — Cheesecake is one of the fattiest desserts here and one of the few with real acidity of its own, so the drink needs sugar, acid and enough of both; a cryoconcentrated cider supplies all three.
- Christmas pudding — Dried fruit concentrates sugar to a level that flattens almost anything, and the suet adds a substantial fat load; a cryoconcentrated cider is high enough in both sugar and acid to stay in balance.
- Ice cream — Ice cream contains far more sugar than it tastes of, because cold suppresses sweetness perception; as it melts on the palate the full sweetness emerges, and only a concentrated style stays ahead of it.
- Roquefort — Ewe’s milk carries more fat than cow’s and a higher proportion of short-chain fatty acids, so this cheese needs both sugar against the salt and acid against the fat. Cryoconcentration raises both at once.
- Tarte Tatin — Caramelisation pushes the sugar level very high, so only a concentrated style stays in balance; ice cider also shares the cooked-apple and caramel volatiles directly, and its acid cuts the butter.
- Bakewell tart — The jam layer keeps real acidity beneath the sugar, so the drink needs both; a cryoconcentrated cider is one of the few styles that carries high sugar and high acid together, and the almond fat needs clearing.
- Doughnuts — Frying oil and a sugar glaze together need both mechanisms at once, and a cryoconcentrated cider is the only part of the family that carries sugar and acid at the levels required.
- Treacle tart — Golden syrup is close to pure sugar, so this is one of the few dishes where even a sweet cider can be flattened; the acid retained in a cryoconcentrated cider is what keeps the pairing from becoming syrup on syrup.
- Pork sausages — A concentrated dessert style against a savoury salted sausage is a mismatch in both intensity and direction: the sugar has no bitterness or extreme salinity to suppress and reads as syrup beside the meat.
- Pork pie — A concentrated sweet style is far past what the salt requires, and its sugar and viscosity add to a food already heavy with lard pastry.
- Pulled pork — A concentrated dessert style is far past what even a sweet barbecue sauce requires, and its viscosity adds to a dish already rich with rendered fat.
- Ploughman’s — A concentrated dessert style is far past what a savoury cold plate requires; its sugar has too little bitterness and salt to suppress, and its viscosity sits oddly against bread and cheese.
What can go wrong
Faults this style is particularly exposed to, given how it is made.
Stuck fermentation
A fermentation that has stopped before the sugar is gone and will not restart, leaving a sweet, low-alcohol cider that is vulnerable to everything.
Oxidation
The cumulative effect of oxygen on finished cider: fruit aroma flattens, colour deepens towards amber, and a bruised-apple or sherry-like character replaces the fresh one.
Unwanted refermentation
Fermentation restarting in a sealed container, generating carbon dioxide that was not planned for and pressure that a bottle may not withstand.
Cooked character
A stewed-apple, caramel or jam-like character from heat applied to juice or cider, most often through pasteurisation or hot storage.

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.
- What temperature should cider ferment at — Most cider is fermented cool, commonly between about 12 and 18 °C. Cooler ferments keep more fruit aroma and run slower; above the low twenties the cider tends towards hot, solvent-like higher alcohols.
- Why did my cider stop fermenting — The usual causes are a shortage of yeast-available nitrogen, a temperature that has dropped, too much sulphite at the start, or a yeast that has reached its alcohol limit. Check the gravity before assuming anything is wrong: many ciders simply finish.
- How do you stop cider from fermenting — By removing the yeast, by chilling, by filtering it out, by pasteurising, or by a combination — and in practice a home maker cannot reliably stop a ferment mid-way with chemicals alone. Sorbate prevents yeast multiplying but will not stop an active ferment.
- What is oxidation in cider
- Why did my sweetened cider start fermenting again — Live yeast met the sugar that was added back. Sweetening is only stable if the yeast has been removed by sterile filtration, killed by pasteurisation, or held in check by sorbate together with sufficient sulphite.
- Is a bruised apple character in cider a fault — The brown, soft, faintly sweet note of enzymatic browning, met wherever apple tissue or juice has met air.
