How it is classified
Perry pear classification
Medium sharp
Moderate acid with low to moderate tannin.
Moderate acid with light tannin, from the collection’s own descriptive material.
Every classification on CiderHQ names its system. Why there is more than one.
What it contributes to a blend
A direction, not a measurement. These bands are the level of resolution the evidence supports, and they say which way adding this fruit pushes a blend rather than what the finished cider will be.
| Axis | Typical | Range |
|---|---|---|
| Acid | Moderate | |
| Tannin | Light | |
| Sugar | Moderate | |
| Bitterness | None | |
| Astringency | Noticeable | |
| Aroma | Present | |
| Body | Medium |
Collection descriptive material. These bands were authored from description; published analyses of this fruit have since been transcribed onto the record from named trial programmes and are shown above. The bands are not derived from those figures, which is why this profile is marked as classified rather than measured.
A green, late-ripening fruit giving a moderately sharp juice with a light dry edge.
Aroma
No aroma descriptors are recorded for Hartpury Green, and for a great deal of cider fruit that is a finding rather than a gap. Bittersweet apples in particular contribute tannin, sugar and body while being close to aromatically mute, and most of what a cider made from them smells of was produced by the fermentation rather than carried in by the fruit. CiderHQ publishes the absence rather than filling the space with descriptors nothing supports.
Measured analysis
Each figure is shown with where and when it was taken. They are not averaged: the same cultivar grown in another climate genuinely gives different numbers, and collapsing them into one would be the most misleading thing this page could do.

How these were measured
- Juice pressed from fruit collected in the Three Counties and frozen before analysis. Published to five decimal places and shown at the three the site displays.
- Titration, reported as malic acid.
- “True tannin” — the polymerised phenolic fraction, measured separately from the phenolic acids. Published in grams per litre and stored here in milligrams per litre by exact conversion.
- Phenolic acids measured separately from the tannin fraction. Published in grams per litre and stored here in milligrams per litre by exact conversion.
- The sum of the true tannin and phenolic acid fractions as the surveyor reports it. Published in grams per litre and stored here in milligrams per litre by exact conversion.
- HPLC. The whole amino acid pool by mass, assimilable and non-assimilable together.
- Free amino nitrogen, calculated from the individual amino acids as nitrogen available to yeast. Excludes proline.
- HPLC.
- One sample from one source in one season. The surveyor reports the same variety differing markedly between years, sites and tree types, and publishes the samples separately rather than pooling them.
- Measured as “true tannin” — the polymerised phenolic fraction — separately from the phenolic acids. It is not a Folin–Ciocalteu total and not a permanganate total, and should be compared only with figures produced the same way.
- Perry pear juice runs far lower in assimilable nitrogen than cider apple juice, a difference the Long Ashton workers reported and this survey confirms across most of the varieties sampled. Several readings here sit below the level at which a ferment is generally expected to need feeding.
- Proline is an amino acid a wine or cider yeast cannot assimilate without oxygen, so it does not count towards usable nitrogen. In these pear juices it routinely exceeds the whole assimilable amino pool, which is why a perry must can be rich in amino acids and starved of nitrogen at the same time.
Compare within a study to see where these figures sat among the other cultivars the same work analysed — which is a more robust statement than the figures themselves, because absolute values move between laboratories and the ordering inside one study mostly survives.
Watched in the orchard
What named research programmes recorded about this fruit at their own sites. Bloom, harvest and cropping belong to a place and a run of seasons rather than to a cultivar, so they are reported site by site rather than merged.
Three Counties perry pear juice survey
Gloucestershire, Herefordshire, Worcestershire and neighbouring counties — the perry country itself, rather than a research station elsewhere · 2022–2024 · Cider and Perry Academy (Peter Mitchell)
The lower Severn and Wye vales: mild, wet, and the only ground in Britain where perry pears have ever been grown at scale. Fruit was collected across three autumns, and the survey reports each collection separately rather than pooling the seasons.
- Held as
- Sample HG-Oct22
Juice from single varieties, frozen before analysis. Specific gravity; titratable acidity by titration as malic acid; “true tannin” and phenolic acids measured as separate fractions; individual amino acids by HPLC, with free amino nitrogen calculated from them and proline reported apart because yeast cannot assimilate it anaerobically. Where samples differed by location, tree age or year, they are reported separately.

October. Later than much of the Gloucestershire crop, which gives it a use at the end of a pressing season. The National Perry Pear Collection records it ripening in the first half of October at Hartpury, one band earlier than the late window recorded here.
Mid-season. Self-incompatible. The National Perry Pear Collection places it in the mid flowering band, from flowering records kept over many seasons.
Pears are not self-fertile. A variety needs another in blossom at the same time to set fruit, which is why the flowering band matters more in a perry orchard than the harvest window does.
Ripening moves with the site and the season. Where the National Perry Pear Collection’s observation at Hartpury falls in a different band from the window recorded here, both are kept rather than one overwriting the other.

Made alone occasionally, giving a clean, moderately sharp perry.
About Hartpury Green
Hartpury Green is named for a Gloucestershire parish in the Leadon valley, a few miles north-west of Gloucester, which is now the site of the national perry pear collection. That collection is the reason perry pear identity is a tractable problem at all: it holds trees of the great majority of surviving English perry pear cultivars in one place, where they can be compared side by side rather than described separately from memory in different counties.
The pear is green, ripens late, and gives a moderately sharp juice with a light dry edge. Late ripening is its practical value: it extends a pressing season past the point where the September and early October fruit has gone.
The cultivar is not distinguished, and this record does not pretend otherwise. Its interest lies in where it comes from, and in the accident by which an unremarkable parish pear shares a name with the institution that keeps the rest of them in existence.
Names, origin and identity
Cultivar naming is the hardest problem in cider fruit data. The same tree carries different names across ten miles, and two different trees have shared a name for two centuries.
Origin · traditional account
Parish tradition. Hartpury is now the site of the national perry pear collection, which gives the name a currency it would not otherwise have.

The National Perry Pear Collection’s identifications are supported by DNA analysis of the trees it holds, which is why they are treated here as the stronger account where they conflict with a documentary one. Where the collection records a name for two varieties it holds as distinct, the name identifies a group of trees rather than one variety, and fruit offered under it needs checking against something other than its label.
Why it matters
- Shares its name with the parish that holds the national perry pear collection, the body that has done most to establish which perry pear is which.

A Dymock perry pear named after a nineteenth-century grower called Bishop, and now better known through the washed-rind cheese that is bathed in its perry.
Where it grows
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 is perry — Perry is an alcoholic drink made by fermenting the juice of pears, traditionally of specific perry pear cultivars rather than eating pears. It is to pears what cider is to apples, and has its own history in the three counties of England and in Normandy.
- When are cider apples harvested — In the northern hemisphere the cider harvest runs from about September to November, with late bittersweets such as Dabinett and Vilberie coming in last. Cider fruit is generally picked riper than dessert fruit, and often gathered from the ground.
- What is juice blending
- How are perry pears classified — Perry pears are conventionally divided by acid and tannin into sweet, medium sharp, bittersharp and bittersweet, following the scheme used in the English perry literature. Sorbitol content matters too, and it does not appear in the classes.
- What is still perry
- What is herefordshire cider

Read on 2026-08-24 — and the address CiderHQ had registered, perrypears.co.uk, is no longer the Centre at all. It fails the TLS handshake over https, and over plain http it resolves to a Sedo domain-parking page: an earlier pass in this sprint recorded it as retrieved on the strength of an HTTP 200, which was wrong, and the correction is the point. The Centre publishes at nationalperrypearcentre.org.uk. It is the closest thing British perry has to an identity authority: it holds at least two examples of most known varieties, states that the DNA of most of them has been determined and is used as an aid to identification, and publishes a variety register with synonym lists. Its 121-variety register is transcribed into the perry pear records, including the nineteen names it shows being claimed by more than one variety.
