Comparison
Asturian vs Basque cider
What is the difference between Asturian sidra and Basque sagardoa?
In short
Both are dry, unfiltered, spontaneously fermented ciders made without sulphite, and both are served by a pour that aerates the liquid. Neither is a variant of the other; they are parallel traditions on either side of the same coast.
Asturian sidra natural is poured — escanciado — from a bottle held high into a glass held low, one small measure at a time, in a sidrería or at the llagar. Basque sagardoa is more associated with the txotx: the cider is drawn from a barrel through a small opening, the drinker catching the stream in a glass, in the sagardotegi season.
The fruit differs too. Basque cultivars and Asturian cultivars are largely distinct sets, and Basque cider is often perceived as the more acidic and the more austere of the two. Both are protected: Sidra de Asturias as a PDO and Euskal Sagardoa as its Basque equivalent.
The two things being compared
Each side described in its own terms first, so the table below has something to hang on.
Asturian *sidra natural*
Dry, still, unfiltered, wild-fermented cider from Asturian cultivars, poured from height as a culín and drunk immediately.
Basque *sagardoa*
Dry, still, unfiltered Basque cider, characteristically acidic, associated with the txotx pour direct from the barrel in the sagardotegi.
Where they differ
Dimension by dimension. Where a row needs a qualification, it carries one rather than being simplified until it fits.
| Dimension | Asturian *sidra natural* | Basque *sagardoa* |
|---|---|---|
| Cultivars | The Asturian permitted-variety list, dominated by semi-sharp fruit. | A largely distinct Basque cultivar set. |
| Acidity | High. | Often higher still, and more austere. |
| Service | Escanciado from a raised bottle into a glass held low. | Txotx — a stream drawn from the barrel and caught in the glass. |
| Setting | Sidrería and llagar, year-round. | Sagardotegi, with a defined season when the barrels are opened. |
| Designation | Sidra de Asturias, a PDO with a permitted-variety list. | Euskal Sagardoa, with its own specification and permitted varieties. |
| FermentationThe traditions agree closely on fermentation; they diverge on fruit and on service. | Spontaneous, unsulphited, cool and slow. | The same. |
| Meal culture | Tapas and small plates alongside the pour. | A set menu of cod omelette, cod with peppers, steak and cheese with walnuts and quince. |
Notes under a dimension name qualify the whole row, not one column.
When Asturian *sidra natural* is the relevant one
The circumstances in which this is the thing being described, rather than a reason to prefer it.
- The cider is Asturian and poured from a bottle.
- You are describing the sidrería and its year-round service.
When Basque *sagardoa* is the relevant one
The circumstances in which this is the thing being described, rather than a reason to prefer it.
- The cider is Basque and drawn from the barrel.
- You are describing the sagardotegi season and its accompanying menu.
A misconception worth clearing up
This comparison exists partly because of the claim below, which is repeated often enough that most readers arrive holding it.
Basque cider is Asturian cider made in the Basque Country.
What is actually the case: They are separate traditions with distinct cultivars, distinct designations and distinct service. The shared features — dryness, wild fermentation, no sulphite, an aerating pour — are common inheritance along one coast, not one tradition borrowed by the other.
Related comparisons
Distinctions that turn on the same thing, or that this one is routinely confused with.
English vs Spanish cider traditions
Two complete traditions with different premises: the English builds structure from tannic fruit and manages sweetness and carbonation; the Asturian and Basque build acidity and wild-ferment character and animate the drink at the moment of pouring.
English vs Spanish classification
The Asturian scheme sorts fruit by acid and bitterness into five classes including a semi-sharp group with no English equivalent, on thresholds fitted to Asturian cultivars rather than English ones.
Wild vs cultured fermentation
A wild ferment runs on the yeasts already present on the fruit and in the building; a cultured one is started with a selected strain in sufficient quantity to dominate from the beginning.
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.
- What is the difference between wild and cultured fermentation in cider — A wild fermentation is carried by the yeasts already on the fruit and in the press house, in a succession of species; a cultured one is started by pitching a single chosen strain. Wild ferments are slower, more variable and can carry aromas a single strain does not make.
- Why is spanish cider so different from english cider — Asturian and Basque cider is fermented dry, is usually not carbonated, and is poured from a height to aerate it in the glass. English cider is more often sweetened, more often carbonated and rarely poured that way, and the two traditions use different fruit and different classification systems.

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.

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.
