How it is classified

Long Ashton classification

Sharp

High acid, low tannin. Includes both purpose-grown sharps and many culinary apples.

Basis: Above about 0.45% w/v acid and below about 0.2% w/v tannin.

Assessed in Fruit grown in New York State trial plantings.

A modern research assignment. No historic American classification exists for this or any other colonial 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: published analysis

Cornell acid figures from New York fruit, with the remaining axes set from consistent modern maker description.

Nutty, faintly pear-like russet character over a firm acid backbone; the juice tastes older and denser than its gravity suggests.

Aroma

Descriptors associated with this fruit. Each names a character with a known cause, and association is not a promise — what reaches the glass depends on the ferment as much as on the apple.

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.

Measured on the fruit

Measured on the fruit itself, before anything was done to it. These figures hold whatever was later made from the juice.

5 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
  • Permanganate titration against indigo carmine, reported as tannic acid equivalent
  • Titration, reported as malic acid equivalent
  • Published as 2.47 inches; converted at 25.4 mm to the inch
  • Juice pressed from 25 fruit, 2015–2017 only. Published as 202 mL/lb; converted at 2.204623 lb to the kilogram
  • Mean of the fruit sampled per accession; where a bracket is shown it is one standard deviation either side of the mean, not the observed range. Published to two decimal places and shown at the precision CiderHQ displays for the unit.
  • Mean of the fruit sampled per accession; where a bracket is shown it is one standard deviation either side of the mean, not the observed range.
  • Cornell generic starch–iodine chart, 1–8, where 1 is no hydrolysis and 8 is complete. Mean of replicate fruit; a bracket, where shown, is one standard deviation either side of it.
  • Penetrometer, mean of replicate fruit; a bracket, where shown, is one standard deviation either side of the mean.
  • Refractometer on pressed juice. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Titration to pH 8.1 with sodium hydroxide, reported as malic acid equivalents. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • The starting pH recorded by the autotitrator before titration, on juice stored frozen at −80 °C and thawed; the source describes no separate pH measurement. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Folin–Ciocalteu assay against gallic acid standards, published in grams per litre of gallic acid equivalent and stored here as milligrams per litre by exact conversion. The source converts these figures to Löwenthal tannic acid equivalents, by a laboratory factor of 1.6, only to sort its accessions into classes; the figure here is the unconverted one.
  • Enzymatic assay (Megazyme). Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • D-sorbitol/xylitol assay kit (Megazyme), sorbitol dehydrogenase method. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Mean fruit weight as published. The compiler notes that a typical New York dessert apple weighs about 140 g, so most of these are small fruit — which is normal for cider cultivars and is itself the point of the column.
  • Titration, reported as malic acid. Analysis of finished cider.
  • Meter on finished cider.
  • Method not stated by the source, which is a real limitation: different tannin methods give wildly different figures on the same sample.
  • Glucose, fructose, sucrose and sorbitol: Not used in any distribution, ranking or comparison. This programme’s enzyme-assayed sugars do not reconcile with its own refractometer readings across the collection — for many varieties the sugars add up to more than the Brix reading allows. The figures were checked against the thesis’s own tables in October 2026 and are transcribed exactly: the disagreement is in the published source, which does not say which reading is wrong. Proportions between glucose, fructose and sucrose, which came from one assay, are still used in summary.
  • Reported as malic acid across seasons. Acid in russets falls markedly if the fruit is held in store before milling, so a pressing-day figure and a picking-day figure are not the same measurement.
  • A chart position, not a quantity. Almost every accession here scored at or near 8, which says the fruit was picked at or past full starch conversion rather than that the cultivars are alike.
  • One harvest at one site. Soluble solids move several degrees between seasons and with crop load.
  • A Folin–Ciocalteu figure counts everything that reduces the reagent, not tannin alone, and is not interchangeable with a Löwenthal permanganate figure for the same juice. Compare this reading with other Folin–Ciocalteu readings in gallic acid equivalents.
  • Reaches CiderHQ through a transcription of a 1989 food-technology chapter, which itself printed unpublished 1980 work from the station. Unlike the chemistry in this dataset it is a measurement of the fruit rather than of the finished cider, so it is comparable with other fruit weights.
  • Measured on finished cider after a spontaneous fermentation, not on juice. It is not comparable with a juice figure for the same cultivar, and the gap between the two is not a disagreement between laboratories — it is what fermentation did.
  • Measured on finished cider after a spontaneous fermentation, not on juice. It is not comparable with a juice figure for the same cultivar, and the gap between the two is not a disagreement between laboratories — it is what fermentation did. The compiler notes these tannin figures run at roughly half the Long Ashton juice figures for the same cultivars, and cannot say how much of that is fermentation, how much is Geneva, and how much is method.

Where it sits among the varieties each programme measured

Roxbury Russet 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.

USDA-PGRU Malus germplasm characterisation

USDA-ARS Plant Genetic Resources Unit, Geneva, New York, in the Finger Lakes region of western New York State · 2017 · Cornell University / USDA-ARS Plant Genetic Resources Unit

Humid continental, with cold winters and warm summers moderated by the Finger Lakes — a sharper seasonal swing than any of the European cider regions whose fruit the collection holds, and warm enough in late summer to bring acid down faster than a maritime autumn does.

A traditional winter keeper, which is a large part of why it survived three centuries of changing fashion.

Juice and pressing

How it is used

On its own

Established as a single-varietal cider

Bottled single-varietal by several New England producers. It has enough acid to structure itself and enough aroma to be recognisable, though it lacks the tannin to give real length.

About Roxbury Russet

Roxbury Russet has the longest continuous history of any apple raised in North America, and it earned that longevity by being useful in several ways at once: it kept until spring, it cooked, it ate acceptably once mellowed, and it pressed well. In a farm economy that had no way to specialise, that combination mattered more than excellence at any single job, and it is the reason this cultivar came through the nineteenth century when purpose-bred cider fruit such as Harrison did not.

The juice is a proper sharp. Cornell figures from New York fruit put the acid comfortably above the Long Ashton sharp threshold, and there is enough sugar behind it to ferment to a cider with body rather than a thin one. The russet skin carries a nutty, slightly pear-like aroma into the juice, and unusually that character persists through fermentation instead of being stripped out with the fruit esters.

Its weaknesses are orchard weaknesses rather than juice weaknesses. It biennially crops without thinning, and it takes fire blight seriously enough to matter in the mid-Atlantic and the Midwest — a hazard that dominates North American orchard planning and is very nearly absent from English cider-fruit description, because the pathogen is not established in Britain to the same degree.

For a modern maker, the practical value of Roxbury Russet is that it is available. Much of the argument about which heritage cultivars the American revival should be built on is really an argument about which ones survived, and this is one that did, in nurseries and in old orchards, without needing to be rescued.

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 · documented

The Roxbury origin is carried consistently by early American pomology and by the collections. The frequently repeated precise date of raising is not supported, and this record does not give one.

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.
