Cider apple

Jonagold

A 1943 Geneva cross of Golden Delicious and Jonathan, triploid and large-fruited, which became a major European as well as North American crop and gives a juice with good sugar and useful acid.

Also written Jonagold, Jonagored.

How it is classified

No recorded classification

No classification scheme has been recorded for Jonagold. That is common outside Europe: the English, French and Spanish systems were each built for their own fruit, and a cultivar grown where none of them applies simply has no class. What the fruit contributes to a blend is described below regardless — the class is a shorthand for that, not a substitute.

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: published analysis

WSU acid and Brix figures from western Washington fruit, with the remaining axes from description.

Rich and honeyed from its Golden Delicious side with a sharper, more aromatic edge from Jonathan; a fuller juice than most dessert fruit.

Aroma

No aroma descriptors are recorded for Jonagold, 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.

One property here has 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
  • Refractometer on pressed juice.
  • Meter on pressed juice.
  • Titration, reported as malic acid. Published to two decimal places and shown at the one the site displays.
  • Folin–Ciocalteu, reported as gallic acid equivalents.
  • Reported as malic acid from maritime western Washington. Jonagold grown in the dry irrigated interior of the state ripens differently and would not be expected to give the same figure.
  • Refractometric, calibrated on sucrose. Good for a dessert apple and well below the russets and crabs in this file.
  • A Folin–Ciocalteu figure in gallic acid equivalents. It is not interchangeable with a Löwenthal permanganate “tannin” figure: the two assays respond to different things and can differ by a factor of two on the same juice.

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.

Virginia cultivar polyphenol characterisation

Winchester, in the northern Shenandoah Valley, Virginia · 2012–2013 · Journal of Agricultural and Food Chemistry

Humid subtropical shading into continental, with hot summers — warm enough that acid falls faster through the ripening period than it does in a maritime autumn, which is part of why the titratable acidities here run lower than English figures for comparable fruit.

Triploid, so it needs two compatible diploid pollinators and gives nothing back.

Triploid

A triploid carries three sets of chromosomes rather than two, and its pollen is effectively sterile. It cannot pollinate another tree and needs two compatible pollinators of its own, which is a real constraint on how an orchard containing it has to be planted.

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

Better than most dessert fruit as a soloist because the sugar gives it body and the Jonathan side gives it some lift. It still has no tannin and no length.

About Jonagold

Jonagold is what happens when a breeding programme crosses its two most useful parents. Golden Delicious supplies sugar, size and a honeyed richness; Jonathan supplies acid and an aromatic lift; the result is a large triploid apple that became a mainstay in Belgium, Germany and the Netherlands as much as in New York and Washington.

As pressing fruit it is one of the better dessert apples. The sugar is genuinely good by dessert-apple standards, the acid usually clears the sharp threshold, and the juice has more body than a Gala or a Red Delicious. None of that makes it cider fruit in the West Country sense — there is no tannin whatever — but a blend built on Jonagold starts from a better place than one built on Rome or York.

The measurements above are from maritime western Washington, and the caveat about the interior of the state is not a formality. Washington grows apples in two utterly different climates: a wet, cool maritime strip west of the Cascades and a hot, dry, irrigated interior east of them. The same cultivar in those two places gives different juice, and a figure without a site attached would be worse than no figure at all.

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.

Parentage · a recorded cross

Recorded as a cross by the breeding programme that made it, which is strong evidence about what was intended and weaker evidence about which pollen took; no genotyping study CiderHQ has read confirms it.
