Thorn

How it is classified

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.

Small green fruit giving a fragrant, lightly sharp juice with almost no astringency, at its most expressive within days of milling.

Aroma

No aroma descriptors are recorded for Thorn, 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.

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.

Cropping

Keeping

Poor — mill soon after picking

Mid-September, sometimes earlier in a warm year. Thorn is gathered and pressed quickly; it is one of the cultivars where the traditional instruction to mill on the day of collection is not a counsel of perfection. The National Perry Pear Collection records it ripening in the middle or later part of September at Hartpury, which agrees with the window recorded here.

Older trees settle into a two-year rhythm. The heavy years are very heavy.

Poor even by perry pear standards. The fruit softens from the inside and is unusable within a few days of dropping.

Mid-season flowering. Self-incompatible, as almost all perry pears are. The National Perry Pear Collection places it in the mid flowering band, from flowering records kept over many seasons.

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.

Disease and pest susceptibility

Juice and pressing

• Light acid with a distinct scent
• Ferments fast and clears early
• Very little tannin to carry age

How it is used

• Pressed early in the season for a perry drunk within the year.
• Named in seventeenth-century English writing on cider and perry, and grown continuously in the Three Counties since.

On its own

About Thorn

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.

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

• Among the small number of perry pears whose names can be traced into seventeenth-century print, alongside Barland and Taynton Squash.
• A demonstration of how weakly a name carries identity across three centuries: the continuity of the Thorn name is documented, the continuity of the tree is not.

Related cultivars

Recorded relationships, including the ones this fruit is routinely confused with.

• Similar role

  Moorcroft

  Both are early, low-tannin pears used to open the pressing season, and both are named loosely in orchard records.

• Often confused with

  Taynton Squash

  Both appear in early literature and both have been used as general labels for old Gloucestershire perry pears of uncertain name.

Fruit that plays a similar part

Cultivars sharing a classification under the same system and a comparable role in a blend. Not a similarity score — a stated relationship.

• Hendre Huffcap

  The most highly regarded of the Huffcap group of perry pears, taking its first name from a Monmouthshire farm and its second from a word for a drink strong enough to lift a hat.

• Moorcroft

  An early Malvern-country perry pear, known as Malvern Hills as often as by its own name, and at the centre of one of the sharpest identity disputes in perry.

• Blakeney Red

  The most widely planted perry pear of the Three Counties, taking its name from the Gloucestershire village of Blakeney and grown for perry, for canning and, during the First World War, for dye.

• Gregg’s Pit

  A Herefordshire perry pear named after the Much Marcle holding where the original tree still stands, and one of the few perry pears whose parent tree can be visited.

• Stinking Bishop

  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.

• Burgundy

  A deeply coloured Monmouthshire perry pear, one of the Welsh cultivars located and propagated by survey work after being reduced to a handful of trees.

Styles it is characteristic of

• Perry

  The fermented drink of pears, a tradition parallel to cider rather than derived from it, in which unfermentable sorbitol leaves a sweetness the maker never chose.

• Bottle-conditioned perry

  Perry that completes its fermentation in the sealed bottle, generating carbonation and lees character while the fruit’s sorbitol keeps a sweetness the yeast cannot remove.

• Sparkling perry

  Perry carrying a persistent bubble, a presentation that suits pear’s aromatics and residual sorbitol and has a documented history going back to the seventeenth century.

• Still perry

  Perry without carbonation, in which the fruit’s sorbitol sweetness and its texture carry a drink that has no bubble to lean on.

• Three Counties cider

  The shared cider and perry tradition of Herefordshire, Gloucestershire and Worcestershire, defined by a common fruit inventory and by the perry pear orchards that survive nowhere else in comparable numbers.

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.
• How are apples milled for cider
• How is sparkling cider made
• 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.
• 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 bottle conditioned perry

  Bibliographic record verified on 2026-08-25 against Open Library, which records the work as Luckwill, 1963, published for the National Fruit and Cider Institute by the University of Bristol. The catalogue entry names Luckwill alone where the standard citation names Luckwill and Pollard as joint editors; CiderHQ keeps both names and records the discrepancy rather than silently following one catalogue. This is the foundational descriptive work on English perry pears and the ancestor of most later variety lists. No copy was opened: it is sixty years old, out of print, and held in research libraries rather than in open digital collections.

  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.

  Identified on 2026-08-24 from the 1670 edition held by the Internet Archive. The attribution needs correcting and CiderHQ has corrected it: *Pomona* is not a book by John Evelyn. It is an appendix annexed to Evelyn’s *Sylva*, published by express order of the Royal Society, and the contributors recorded for the volume are John Evelyn, John Beale, Daniel Colwall, Paul Neile, John Newburgh and Sylas Taylor. Beale has his own entry in this register, and the overlap is not a coincidence — the two texts come out of the same Royal Society enquiry into cider in the 1660s. Citing *Pomona* as Evelyn’s flattens a collaborative compilation into a single-author work.
