How it is classified

Perry pear classification

Bittersharp

Acid and tannin together; the most structured perry pears.

High tannin with substantial acid. Butt is among the most tannic perry pears in the English record, and it is the cultivar most often cited when perry writers note that the class labels understate how astringent a pear can be.

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.

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

The bittersharp placement in the Long Ashton account, with astringency at the top of the range on the consistent description of a markedly drying juice.

A hard, late, heavily astringent fruit giving a juice that dries the mouth from the first sip and needs both time and dilution by other pears to become drinkable.

Aroma

No aroma descriptors are recorded for Butt, 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.

3 properties here have been measured more than once. The readings are shown as they were taken and are deliberately not averaged — climate, season, ripeness at picking, the age of the tree and the analytical method all move these numbers, and a single figure would hide every one of them. Where a spread is given below a property, it is the distance between separate studies, not the variation within any one of them.

How these were measured
  • Juice density. Published by the source in the four-figure form (1058) and written here in full.
  • Titration, reported as malic acid. Published as a percentage and stored here in grams per litre by exact conversion — one per cent weight per volume is ten grams per litre — so that the historic figures sit in one column with the modern survey the site also holds.
  • Löwenthal permanganate titration. Published as a percentage and stored here in milligrams per litre by exact conversion — one per cent weight per volume is ten thousand milligrams per litre — so that the historic figures sit in one column with the modern survey the site also holds.
  • 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.
  • Juice gravity of the separate batch taken for the single-variety fermentation trial, before any sugar adjustment.
  • Meter on the fermentation-trial juice before adjustment.
  • A general pear juice figure, not a Butt analysis. Recorded here because the interaction matters: a heavily astringent perry retains sorbitol sweetness that softens the tannin in a way an equivalently tannic cider cannot. The range is not tied to a single study or season.
  • Long Ashton perry pear analyses, reaching CiderHQ through a National Association of Cider Makers report compiled in 2010 from the station’s material. The underlying volume is Luckwill and Pollard, Perry Pears (University of Bristol, 1963), which CiderHQ has verified bibliographically and not opened. The compiler warns that juice quality in perry pears improves markedly with tree age, and that young trees give weaker acid and tannin and a lower gravity. A single figure for a perry pear is therefore a figure for a tree of some unstated age.

The underlying volume is Luckwill and Pollard, Perry Pears (University of Bristol, 1963), which CiderHQ has verified bibliographically and not opened. A permanganate figure, not comparable with a Folin–Ciocalteu total-phenolics figure.
  • 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.
  • The four fermentation trials were chaptalised by differing amounts to hit a common alcohol target, so the finished strengths are not a property of the fruit and CiderHQ does not record them as measurements. The juice gravity and juice pH below are measurements of the juice as pressed, before any adjustment.

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.

Long Ashton perry pear varieties

Long Ashton Research Station, near Bristol, North Somerset, England · 1903–1963 · National Association of Cider Makers, Archive of Cider Pomology

Maritime and mild. The station sat outside the perry counties it studied — the pears are Gloucestershire, Herefordshire and Worcestershire fruit — which is worth holding in mind when a figure here is compared with one measured on fruit picked in the Three Counties.

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 October into November, and the last of the Three Counties perry pears in most seasons. The fruit is hard when it falls and does not soften usefully, so the usual instruction to mill on the day of gathering matters less here than for any other perry pear. The National Perry Pear Collection records it ripening in November at Hartpury, which agrees with the window recorded here.

The biennial habit is pronounced. A heavy year can be followed by almost nothing, which makes a single-variety Butt perry an intermittent product.

Unusually good for a perry pear. The hard flesh holds for a week or two, which is one of the reasons Butt could be worked at the end of a long season.

Mid to late flowering. Self-incompatible. The National Perry Pear Collection places it in the late 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.

Juice and pressing

How it is used

On its own

Sometimes bottled on its own

Made alone, and demanding when it is. A young single-variety Butt perry is severely astringent; the tannin softens with time in the way apple tannin does, but more slowly, and the sorbitol sweetness underneath it is what makes the result balanced rather than merely hard.

About Butt

Butt is the perry pear that disproves the general impression of perry. Where most of the Three Counties crop makes something light, quick and low in tannin, Butt makes a juice so astringent that a mouthful of it is uncomfortable, and a perry that needs time before it becomes anything else. It ripens at the very end of the season, in late October and into November, and the fruit is hard enough that it holds for a week or two rather than rotting in days — which for a perry pear is remarkable.

Its tannin is the point. Perry pear tannin generally presents as astringency rather than bitterness, and Butt is the extreme case: it dries the whole mouth rather than tasting bitter at the back of the tongue. Used in small proportion it gives a soft blend a spine it could not otherwise have. Used alone it produces something that a maker has to be patient with. What keeps a single-variety Butt perry in balance is the sorbitol: the unfermentable sweetness sits underneath the tannin and stops it reading as harshness, an interaction that has no equivalent in cider.

The name is a tangle. Butt has been recorded in more than one Herefordshire parish for trees that are not obviously the same, Bloody Butt circulates as a further name of uncertain application, and the cultivar is confused with Barland in orchard records often enough that the pairing is worth stating explicitly. The trees are very vigorous, slow to bear, and severely biennial: a heavy crop can be followed by almost nothing, which is why single-variety Butt perry appears and disappears from year to year rather than being a standing product.

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

Origin unrecorded. The name has been applied in more than one Herefordshire parish to trees that are not obviously the same, which is the ordinary condition of perry pear naming rather than a peculiarity of this cultivar.

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.
NameKindNote
Norton ButtRegional nameRecorded as a synonym of Butt by the National Perry Pear Collection.
Bloody ButtDisputed identityRecorded in some Herefordshire orchards. Whether it names this cultivar, a red-fruited relative or a separate tree is unresolved.

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.
