How it is classified
Asturian technological blocks
Bitter-semi-acid · Amargo-semiácido
Chiefly bitter, with semi-acid behind it — the mirror of the block above, and a different fruit.
Assessed in Asturias, as characterised for the protected designation.
Published by the Consejo Regulador of DOP Sidra de Asturias as “Amargo semiácido”, on total acidity 4,68 g/L as sulphuric acid and total polyphenols 1,93 g/L as tannic acid.
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 | Moderate | |
| Sugar | Moderate | |
| Bitterness | Moderate | |
| Astringency | Noticeable | |
| Aroma | Present | |
| Body | Medium |
The designation’s published figures: 4,68 g/L total acidity as sulphuric acid, 1,93 g/L total polyphenols as tannic acid.
Phenolic by Asturian standards — 1,93 g/L puts it in the top few of the register — with 4,68 g/L of acid behind it.
Aroma
No aroma descriptors are recorded for Montés de La Llamera, 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 acidity4.7 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 phenolics1.9 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.

Asturias, northern Spain · Published characterisation, retrieved 2026-08-24 · Consejo Regulador de la DOP Sidra de Asturias
Atlantic and markedly wet — cool summers, mild winters and high rainfall on the Bay of Biscay coast, a climate that suits high-acid fruit and long, cool ferments.
- Harvest
- the second to third ten days of October (published as “2ª a 3ª decena de octubre”)
Filed here as amargo-semiacido.
Susceptibility to fungal disease: low. Flowering: mid-season to late. Cropping: fairly high to high. 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.

- Total polyphenols 1,93 g/L as tannic acid, ranking 6 of 56
- Cropping recorded as fairly high to high

On its own
Rarely bottled on its own
Asturian practice is emphatically a blending tradition, and single-varietal sidra remains a modern minority interest. Nothing in the published characterisation rules it out; nothing recommends it either.
About Montés de La Llamera
This is the only variety the Consejo files as amargo semiácido — bitter first, semi-acid behind it — which makes it the single occupant of one of the nine technological blocks. The figures behind the placement are 4,68 g/L of acid and 1,93 of polyphenols.
The Consejo records the tree as flowering mid-season to late, ripening in the second to third ten days of October, cropping fairly high to high. Susceptibility to fungal disease is low — worth as much in Asturias as anything in the juice, given the rainfall.
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
Asturian cider varieties were selected in pumaradas over centuries and named parish by parish. No raiser or date is recorded for this fruit and none is likely to be.
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.
Picón
An Asturian cider apple admitted to the protected designation and characterised as acid-bitter — 6,78 g/L of acid well above the register’s median, with 2,01 g/L of polyphenols, ripening in the last ten days of November.
Blanquina
A pale-skinned Asturian cultivar of high reputation, and — like Raxao, with which it is usually named — an acid-block fruit rather than a semi-acid one.
Regona
The most acid cultivar the Asturian designation characterises, at 7,1 g/L, and one of the most planted: a late, hard, acid-bitter fruit that supplies the backbone of *sidra natural*.
Rheinischer Bohnapfel
The classic German *Mostapfel*: a very late, very acid, enormously productive Rhineland cultivar that carried more Apfelwein and Viez through the twentieth century than any other single fruit.
Txalaka
The most widely recognised Basque cider apple: a hard, sharp, late cultivar from Gipuzkoa that supplies much of the acid backbone of *sagardoa*.
Durona de Tresali
A very hard, very late Asturian cultivar from the parish of Tresali, in the acid-bitter block, and one of the last fruits of the season to be pressed.
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.

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.
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.
