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.
Placed as a sharp on description. No analysis exists for this cultivar and the placement is provisional.
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.
| Axis | Typical | Range |

| Acid | High | |
| Tannin | Light | |
| Sugar | Moderate | |
| Bitterness | Slight | |
| Astringency | Slight | |
| Aroma | Present | |
| Body | Medium |
Description in Welsh cultivar records. Nothing measured attaches to this fruit.
Supplies acid to a Welsh blend, with a distinctive pointed fruit that is easy to identify in the orchard.
Aroma
No aroma descriptors are recorded for Pig Aderyn, 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
CiderHQ holds no sourced juice analysis for Pig Aderyn. 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.

About Pig Aderyn
Pig Aderyn means bird’s beak in Welsh, and the fruit is pointed enough to earn it. Welsh cider apple names are frequently descriptive in this way, and unlike the English habit of naming fruit after farmers they tell you something you can check by looking at the apple.
It is a sharp used in Welsh farm blends, conserved rather than commercially grown. Because the name is descriptive it may have been applied independently in different districts, which is the usual hazard with names of this kind, and this record notes the possibility rather than assuming a single clone.
No analysis exists. This entry carries a class placed on description, an explicit note saying so, and no measurements — the same treatment given to any fruit whose numbers are unknown.
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
A Welsh cider apple of unrecorded origin, named in Welsh for the beak-like point of the fruit. The name is descriptive and may have been applied independently in more than one district.
| Name | Kind | Note |
|---|---|---|
| Pig y Aderyn | Regional name | Monmouthshire. The fuller Welsh form. Both are used for the same fruit and neither has priority. |

Fruit that plays a similar part
Cultivars sharing a classification under the same system and a comparable role in a blend. Not a similarity score — a stated relationship.
Bramley’s Seedling
England’s dominant cooking apple, a triploid of very high acid and negligible tannin, and by volume one of the most important fruits in modern British cider.
Browns Apple
The standard Devon sharp: a bright red, heavy-cropping, high-acid apple with almost no tannin, and the fruit most English blends reach for when they need lift.
Granny Smith
An Australian chance seedling of the 1860s that became one of the most planted apples on earth, and — because it is reliably sharp when almost nothing else commercial is — a genuine workhorse of commercial cider worldwide.
McIntosh
The defining apple of eastern Canada and northern New England — an Ontario seedling of about 1811 whose perfumed, high-acid juice is the aromatic foundation of most Quebec and northeastern cider.
Baldwin
The dominant New England apple of the nineteenth century until a single catastrophic winter destroyed the orchards; a firm, moderately sharp keeper still used in northeastern cider blends.
Braeburn
A New Zealand chance seedling found near Motueka in the 1950s, sharper and denser than most modern dessert apples, and one of the better commercial cultivars available to a cider blender.
