How it is classified

Perry pear classification

Medium sharp

Moderate acid with low to moderate tannin.

Moderate acid with light tannin. The hardness of the flesh does not translate into unusual tannin, which surprises people who expect it to.

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

Medium-sharp placement in the Long Ashton perry pear account.

Small, extremely hard fruit giving a moderately sharp juice with a light grip; the perry is plain, and the cultivar’s value is logistical.

Aroma

No aroma descriptors are recorded for Rock, 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

No analysis recorded

CiderHQ holds no sourced juice analysis for Rock. Figures for this cultivar circulate, but they reach the present through compilation rather than through the original tables, and publishing a number we cannot attribute would give it an authority it has not earned. What is known about how the fruit behaves is described above and below.

October, and gathered rather than caught: unlike most perry pears the fruit can be picked and stored before milling. This is the single most useful thing about it. The National Perry Pear Collection records it ripening in November at Hartpury, one band later than the late window recorded here.

Exceptional for a perry pear. The fruit will hold for several weeks in cool conditions without breaking down, which allows a mill to schedule it rather than react to it.

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

How it is used

On its own

Rarely bottled on its own

Occasionally made alone. The perry is unremarkable; the cultivar earns its place by being available when nothing else is.

About Rock

Perry pears are notorious for having almost no margin: the fruit is ready when it falls and is ruined a week later, and a perry maker spends the autumn reacting to trees rather than planning around them. Rock is the exception. The flesh is genuinely hard — hard enough that milling it takes more work than milling any other perry pear — and the fruit will hold for several weeks in cool conditions without collapsing.

That property is the whole point of the cultivar. It allowed a farm to deal with the perishable fruit first and come back to the Rock afterwards, and it allows a modern mill to schedule a pressing rather than to drop everything when a tree lets go. The juice itself is unremarkable: moderate acid, light tannin, a plain perry. People sometimes assume that hard fruit means high tannin, and in this case it does not.

The yield is lower than from soft-fleshed pears and the fruit needs thorough milling to give up what it has. Trees are large standards of the usual perry pear kind, biennial once mature, and long-lived. The tough skin also makes it rather more scab-resistant than most of the Three Counties crop.

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

Unrecorded. The name describes the hardness of the fruit, which is the cultivar’s defining property.

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.

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.
