Dataset
The IFPC cider apple juice characterisation
Twelve French cider apple juices measured by the national technical institute in 2018 — the only French institutional dataset CiderHQ has opened, and the evidence that “French cider apple” is not a composition.
What do French cider apple juices actually measure?
Very different things from one another. Marie Ménard at 2,333 mg/L total polyphenols and Judor at 104 mg/L are both French cider apples grown for the same industry, and they are more than twentyfold apart. Peau de Chien reaches specific gravity 1.079, the highest sugar in the set, while Cuir d’âne sits at 1.049.
The dataset matters out of proportion to its size because the site holds a great many French cultivars and, until this, almost no French numbers: the classification records said which family a fruit belonged to and nothing said what the juice measured.

Climate. Northern French cider country, chiefly Normandy and Brittany: maritime, mild, wet, and the closest continental analogue to the English West Country. The source does not break the samples down by orchard, so the location here is as precise as the evidence allows.
Method. Twelve varieties, one harvest. Malic acid, total acidity, density, pH and total polyphenols measured on pressed juice; sensory profiling run alongside on the same juices. The assay behind the polyphenol column is not named, and the unit behind the total acidity column is not stated.
Presented at a technical day rather than published as a paper, which is why it is registered at research tier and not treated as peer-reviewed. The institute is the body that defines the French classification thresholds, so its own juice figures are the ones those thresholds were meant to be applied to.
What it adds
- It attaches numbers to the French classification for the first time on this site, so a douce or an amère is not only a category label.
- It is institutional rather than commercial, selected by expert advice as recent or commonly planted varieties, which makes it a picture of what the French industry is actually working with.
- It demonstrates the range within a single national repertoire, which is the corrective to treating a country as a style.
What it cannot be asked
Stated as limits rather than as apology. A dataset with known bounds is more useful than one presented as complete.
- Twelve varieties, one harvest, and the source does not break the sample down by orchard or region.
- The total acidity column is withheld on every entry, with the reason attached. The presentation does not state its unit: at the French convention of sulphuric acid equivalents it should sit at about 0.73 times the malic figure, and it sits nearer 0.5, which matches no convention CiderHQ can identify. Publishing a number whose unit is a guess would be worse than publishing nothing, and the malic column — which the source does label — carries the same information.
- Density is published in grams per litre and stored here as specific gravity by exact division. The source states no reference temperature, which is recorded in the method rather than assumed away.
- The institute’s own site is served over plain HTTP and refuses a TLS handshake, so there is no https address to cite.
One French harvest, in northern French cider country — chiefly Normandy and Brittany, maritime, mild and wet. A single season in a maritime climate is a snapshot of a moving quantity, and the source does not say which orchards contributed, so the figures cannot even be tied to an appellation.
What was measured
Every property in the transcription, with how many cultivars carry it. A property measured on some cultivars and not others is a gap in the source, not in the transcription.
| Property | Cultivars | Reported in |
|---|---|---|
| Malic acid | 12 | Grams per litre |
| Specific gravity | 12 | Specific gravity |
| pH | 12 | pH |
| Total phenolics | 12 | Milligrams per litre |
| Cultivar | Total phenolics (mg/L) | Where it sits in this study’s range |
|---|---|---|
| Marie Ménard | 2332.9 | |
| Peau de Chien | 1604.3 | |
| Frequinette | 1173.5 | |
| Marine Auffrais | 1161.3 | |
| Cuir d’âne | 989.1 | |
| Cimes | 916.5 | |
| Doux Crasseux | 899.3 | |
| Jaune de Vitré | 787.8 | |
| Dabinett | 550.9 | |
| Douce de l’Avent | 539.7 | |
| Guillevic | 213.8 | |
| Judor | 103.6 |
Ordering only. Where a figure was published as a range the midpoint is used to place the row, and the range itself — not the midpoint — is what appears on the cultivar’s own page.
What it can be read beside
The commonest way to misuse this corpus is not to misread one figure but to put two side by side that were never measuring the same thing. This is the judgement, stated.
| Dataset | Verdict | Why |
|---|---|---|
| The Long Ashton cider apple table | Not comparable | Malic acid in grams per litre against total acid as percent weight per volume, and phenolics in milligrams per litre against permanganate tannin as a percentage. Neither column converts. |
| The DOP Sidra de Asturias varietal characterisation | Not comparable | Two continental designations, two acid conventions, two phenolic conventions. The nearest thing to a shared axis is that both show enormous within-country range, which is a finding about repertoires rather than a comparison of figures. |
Where a dataset is not listed, no judgement has been recorded and the safe reading is that the two have not been checked against each other. CiderHQ never averages across studies: how evidence is handled sets out why.

Institut Français des Productions Cidricoles (IFPC) · research institute · passage verified 2026-08-25 · covers 2018 harvest
A technical-day presentation by the French cider institute, retrieved and read in full on 2026-08-25. Twelve French cider varieties characterised for malic acid, total acidity, density, pH and total polyphenols, with sensory profiling on the same juices. The first French institutional juice figures CiderHQ has been able to open, and important out of proportion to their number because the site holds many French cultivars and previously held almost no French measurements. The total acidity column is not published by CiderHQ: the slide does not state its unit and the ratio to the malic figure matches no convention the site can identify.

The French cider interbranch organisation’s own briefing on the 2025 décret, read in full on 2026-08-24. It is registered because the primary text could not be retrieved verbatim and this one reproduces the operative sweetness table, and it is registered at tier 2 rather than tier 1 because an interbranch body explaining a decree is not the decree. Where it is cited, it is cited for what the instrument says, alongside the instrument.
