How it is classified

Perry pear classification

Bittersweet

Low acid with substantial tannin — the class that gives perry grip.

Low acid with substantial tannin. Placed from descriptive material rather than from a published analysis of this cultivar.

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 drink will be.

Contribution to a blend, scored 1–5 as a band. The filled segment is the typical value; the paler segments are the range.

Based on: its recorded classification

Descriptive accounts of a low-acid, tannic juice; no analysis of this cultivar has been verified. 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.

Red-flushed fruit giving a juice that dries the mouth without much sharpness behind it.

Aroma

No aroma descriptors are recorded for Red Longdon. Perry pears have been described far less than they have been analysed, and much of what a perry smells of is 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 survey’s column is the total of the primary (assimilable) amino acids, summed by mass; proline, a secondary amino acid, is reported in its own column and is not included. In eleven of the thirty-seven samples proline alone exceeds this figure.
  • 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.

Where it sits among the varieties each programme measured

Red Longdon against every other variety the same programme measured the same way. Repeat samples are reduced to their median first, and where a programme published a range and not a single figure the midpoint of that range stands for it. Laboratories disagree on absolute figures more than on order, so the position is the sturdier reading.

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 RL-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.

Late September into October. As with the rest of the Longdon group the window is short and the fruit is milled promptly. The National Perry Pear Collection records it ripening in the first half of October at Hartpury, which agrees with the 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 need a pollinator

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.

Disease and pest susceptibility

Recorded susceptibility. Pressure differs enormously by region and by season, so these are tendencies rather than predictions.

How it is used

On its own

Rarely bottled on its own

Seldom made alone. The low acid leaves a single-variety perry without much definition, and the cultivar is more useful supplying grip to a blend.

About Red Longdon

Red Longdon is one of the four pears named for the Worcestershire parish of Longdon, and the identity problem it presents is instructive. Four cultivars carry one parish name, distinguished from each other by a colour word or a family name, and an orchard record or nursery order that says only "Longdon" is unresolvable. The four are held separately in the national collection; they are not reliably separated in the field.

This one has red-flushed fruit and a juice that is low in acid and appreciably tannic, placing it among the bittersweets. The tannin presents as astringency rather than bitterness, as perry pear tannin generally does, and the low acid means there is nothing sharp to set it against. That makes it a blending pear: it gives grip to a perry built on softer, sharper fruit and does not make a satisfying perry alone.

The trees are very vigorous standards, slow into bearing and biennial once mature. Like most of the Three Counties perry pears the surviving population is small and concentrated in a few parishes, and what is grown now is largely the result of collection and propagation work rather than of continuous planting.

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. The four Longdon pears were presumably found and named in and around the same parish over an unknown period; nothing about their relationship to one another is recorded.

Other names this fruit is known by. Each is a name for the same cultivar, not a separate one — which is why none of them has a page of its own.

LongdonDisputed identityThe bare parish name covers four cultivars and identifies none of them.

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.
