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.
A sharp when pressed: good acid, negligible tannin. Placed on description; no cider analysis is attached.
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 | Negligible | |
| Sugar | High | |
| Bitterness | None | |
| Astringency | None | |
| Aroma | Pronounced | |
| Body | Light |
Description of an aromatic dessert apple, with aroma banded high because the strawberry-and-red-fruit character is the reason British producers press it.
Brings a strong strawberry-and-red-fruit aroma and clean acid, and gives a cider that tastes emphatically of fresh fruit.
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.
- Strawberry — A soft red-fruit note from furanone and ester chemistry, arising in fermentation or from added fruit.
- Fresh-cut apple — The smell of a cut apple surface, produced within seconds of the fruit tissue being broken by six-carbon aldehydes released from membrane fats.
Measured analysis
CiderHQ holds no sourced juice analysis for Katy. 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.

An early apple with a short life; press promptly.
Mid-season flowering and a reliable cropper in a British climate.

On its own
Established as a single-varietal cider
Genuinely established as a British single varietal, and unusual in this file for being a modern dessert apple rather than a traditional cider one. The cider is pink-tinged, strongly aromatic and tannin-free, and the style has a real following.
About Katy
Katy — Katja in its native Sweden — is a reminder that the British cider repertoire is not closed. It was bred at a Swedish research station for a cold-climate dessert market, took well to British orchards, and was then picked up by cidermakers for a reason nobody breeding it had in mind: it smells intensely of strawberries and that aroma survives fermentation.
A single-varietal Katy cider is a genuinely modern British style. It is pale pink, aromatic, clean, entirely without tannin, and closer in shape to a Nordic or a New Zealand cider than to anything from Somerset. Whether that counts as English cider is a question the category has to answer eventually, and the honest observation is that a good deal of what British producers now sell is made this way.
In a blend it is used sparingly and for aroma. Its acid is useful but not exceptional, its sugar unremarkable, and its aromatic contribution strong enough that ten per cent will be noticeable in a finished cider.
One point of accuracy: this is not a British cultivar. It is grown in Britain and used in British cider, and both its name and its origin are Swedish. Records that present it as an English apple are simply wrong.
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
Raised at the Balsgård fruit breeding station in Sweden and introduced to Britain in the second half of the twentieth century. A documented institutional origin.
Parentage · not established
Given as a cross involving James Grieve and Worcester Pearmain. The cross is consistently reported; it is not independently verified here.
| Name | Kind | Note |
|---|---|---|
| Katja | Trade name | The original Swedish name. Katy is the form used in Britain, and the two denote the same cultivar. |

Discovery
A very early red dessert apple raised in Essex, used by cidermakers to start the season with something aromatic and sharp.
Cheddar Cross
A very early sharp raised at Long Ashton, giving acid at the start of the season when little else is ready.
James Grieve
A Scottish-raised dual-purpose apple of clean, bright acid, widely grown in Britain and pressed for acid and freshness in modern cider.
Sops in Wine
An old English name for red-fleshed apples that stain the juice, applied to several distinct cultivars and identifying none of them reliably.
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.
Golden Russet
The highest-gravity fruit in widespread North American cider use — a small bronze russet from New York whose juice regularly presses above 1.060 and which many revival makers treat as their benchmark cultivar.
Styles it is characteristic of
Eastern counties cider
Cider from eastern and south-eastern England made largely from dessert and culinary apples, giving a lighter, sharper and less tannic drink than the West Country tradition.
Irish cider
Cider from Ireland, dominated commercially by large-scale production from Armagh and imported fruit, with a smaller full-juice sector working from orchard-grown apples.
Scottish cider
Cider from Scotland, made in a cool maritime climate from dessert, culinary and cold-tolerant fruit, in a small sector built largely within recent decades.

What people ask next
Questions readers ask about the things this page mentions. Each one goes to the section that answers it rather than to a page written to receive the question.
- How do you blend cider

- What is juice blending
- How is supermarket cider made
- Is single variety cider better than a blend — Neither is inherently better and CiderHQ does not rank them. A single varietal shows one cultivar’s character and depends entirely on that fruit being balanced; a blend is how most makers reach balance deliberately.
