How it is classified
Asturian technological blocks
Semi-acid · Semiácido
Intermediate acidity with low phenolics. Together with the acid block this is where most admitted fruit sits.
Assessed in Asturias, as characterised for the protected designation.
Published by the Consejo Regulador of DOP Sidra de Asturias as “Semiácido”, on total acidity 3,9 g/L as sulphuric acid and total polyphenols 1,1 g/L as tannic acid. Asturian practice reports acidity as sulphuric acid, so the figure is not directly comparable with an English or North American malic-acid one.
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 | Moderate | |
| Tannin | Light | |
| Sugar | Moderate | |
| Bitterness | None | |
| Astringency | None | |
| Aroma | Present | |
| Body | Medium |
Published figures for the protected designation: total acidity 3,9 g/L as sulphuric acid, total polyphenols 1,1 g/L as tannic acid.
Clean and moderately acid with a modest aroma; a workmanlike fruit that contributes balance and gets out of the way.
Aroma
No aroma descriptors are recorded for Perico, 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.
Titratable acidity3.9 g/L
Asturias, Spain, Published characterisation, retrieved 2026-08-24 · Total acidity expressed as sulphuric acid equivalent, the Spanish convention. Not comparable with a malic-acid figure without conversion: multiply by about 1.37 to reach malic-acid equivalent. · Consejo Regulador de la DOP Sidra de Asturias
Acid measured by neutralisation — the quantity of acid, not its strength. Measured in grams per litre.
Total phenolics1.1 g/L
Asturias, Spain, Published characterisation, retrieved 2026-08-24 · Total polyphenols expressed as tannic acid equivalent. · Consejo Regulador de la DOP Sidra de Asturias
All phenolic compounds together, usually reported as gallic acid equivalents. Measured in grams per litre.
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.

Filed here as semiacido.
Vigour: high. Susceptibility to fungal disease: moderate to low. Flowering: very late. Cropping: moderate. As characterised by the Consejo Regulador.
Total acidity expressed as grams per litre of sulphuric acid, the Spanish convention; total polyphenols as grams per litre of tannic acid. Characterisation carried out by the fruit-research programme of SERIDA and published by the Consejo Regulador.

Juice and pressing
- Acid at 3,9 g/L — semi-acid, and below the regional midpoint
- Phenolics of 1,1 g/L, ordinary for Asturias
- Very late flowering, which gives useful frost avoidance
How it is used
- Acid backbone in sidra natural blends

On its own
Rarely bottled on its own
Reliable rather than expressive, and there is no tradition of bottling it alone.
About Perico
Perico is one of the more widely planted cultivars in modern Asturian orchards, and the Consejo Regulador places it in the semiácido block on 4 g/L of acidity, or 3,9 to be exact, with 1,1 g/L of polyphenols — a step milder than the acid-block cultivars it is often listed beside.
Its useful properties are agronomic. The tree is vigorous, flowers very late — which in a maritime spring is real frost insurance — ripens in the second ten days of November, and carries moderate to low susceptibility to fungal disease. Cropping is recorded as moderate rather than heavy.
It is worth being plain that a semi-acid Asturian cultivar has no English equivalent. The English scheme has no middle: fruit is sharp above 0,45% acid and sweet below it, with nothing in between, and a cultivar like this one falls into a category the four-way division simply does not contain.
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.
| Name | Kind | Note |
|---|---|---|
| Pericu | Regional name | Asturias. The Asturian form of the same familiar name. |

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.
Collaos
A late, moderately-cropping Asturian semi-acid cultivar, ripening at the very end of November — later than almost anything else on the permitted list.
De la Riega
A well-regarded Asturian cultivar in the semi-acid block at 4,3 g/L, low in disease and reliable in crop — balanced rather than sweet, despite a mild eating character.
Carrió
A very late Asturian cultivar in the semi-acid block, vigorous and heavy-cropping, pressed at the winter end of the season.
Clara
A pale Asturian semi-sharp of moderate acid and mild character, permitted within the designation and planted as a blending component.
Solarina
A very vigorous, heavy-cropping Asturian cultivar in the semi-acid block, ripening in late October and carrying a little more phenolic weight than the regional floor.
Durón d'Arroes
An Asturian cider apple admitted to the protected designation and characterised as semi-acid — 4,32 g/L of acid below the register’s median, with 1,23 g/L of polyphenols, ripening in the second ten days of December.
Where it grows
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 does cider ferment — Yeast consumes the sugar in apple juice and produces roughly equal masses of ethanol and carbon dioxide, along with the esters and higher alcohols that give cider much of its aroma. In a wild ferment several yeast species take turns before *Saccharomyces* finishes the job.
- How do you blend cider
- What is sidra natural — Sidra natural is the still, dry, unfiltered cider of Asturias and the Basque Country, bottled without added carbonation and poured from a height to rouse it. It is tart, funky and made to be drunk in small measures poured one at a time.

Sources
What this page rests on. Where a source is marked as registered rather than read, CiderHQ is recording that the body is authoritative on the subject without claiming to have worked through the document itself. See our evidence policy for what each state means.
Servicio Regional de Investigación y Desarrollo Agroalimentario (SERIDA)
Principado de Asturias · research institute · retrieved 2026-08-24
The Asturian regional agri-food research service, and the technical authority behind the Asturian cultivar classification and the analysis of sidra natural. SERIDA’s own site has not been opened; what CiderHQ has read is SERIDA’s varietal characterisation as republished by the Consejo Regulador of DOP Sidra de Asturias, which credits it explicitly. The Asturian measurements therefore cite the Consejo rather than SERIDA — citing the body that did the work, at a document CiderHQ has not seen, would be exactly the kind of borrowed authority this register exists to prevent.
Denominación de Origen Protegida Sidra de Asturias
Consejo Regulador de la DOP Sidra de Asturias · designation authority · passage verified 2026-08-24
The regulating council for Asturian cider. Read on 2026-08-24, and it turned out to carry far more than a permitted-variety list: an agronomic and technological characterisation of each admitted variety, with total acidity, total polyphenols, vigour, flowering, ripening, cropping and susceptibility to fungal disease. The characterisation is credited to SERIDA’s fruit-research programme. Two things it settles are corrections to what CiderHQ previously held: Asturias sorts cider fruit into nine technological blocks rather than five, and it publishes acidity as sulphuric acid rather than malic. The figures are transcribed into `data/trials/serida-asturias.ts` and cite this source, because this is where they were read.
