Terroir
Natural factors
- The comarca is nestled within the Picos de Europa massif, at altitudes exceeding 1,500–2,000 metres, whose mountain ranges shelter the area from incoming Atlantic weather fronts.
- The rugged relief is characterised by Carboniferous limestone, affected by karstic processes, with shales and sandstones on the valley floors.
- The developed soils are acidic in character, and the enclosed, basin-like nature of the area imparts edaphoclimatic conditions distinct from those of the rest of the region.
- According to the J. Papadakis classification, the climate is warm-temperate Mediterranean with a continental character, with moderate annual rainfall of 600–700 mm and dry summers.
- Climatically the comarca would fall within CMO zone C II, although by regulation it is classified in zone C I, with an effective heat summation of 1,567 °C compared with 1,347 °C for the Cantabrian coastal zone.
- The topography forms a large basin enclosed by limestone cliff walls, made up of four valleys converging at Potes, with slopes that often exceed twenty per cent.
- Average maximum temperatures of around 25 °C during the final phase of ripening cause that phase to be slow and extended, which encourages the accumulation of varietal aromas in the grapes.
Human factors
- The document from the Monastery of Santa María de Piasca, dated 822, records the sale of a vineyard in exchange for various goods, making it the oldest written reference to viticulture in Liébana.
- In 1678 some residents of Liébana filed a complaint about the excessive spread of the vineyards, and the growers responded that pruning the vines required men to be roped together because of the steepness of the slopes.
Product characteristics
- The quality of the polyphenolic profile is reflected in the organoleptic analysis of Liébana wines, which display good development and longevity in both young and aged wines.
Terroir / wine link
- The marked diurnal temperature variation encourages the expression of colour and the synthesis, complexity, finesse, and accumulation of aromas from the authorised varieties.
- Moderate daytime temperatures promote the accumulation of sugars and a reduction in acidity, while cool night-time temperatures stimulate greater accumulation of anthocyanins and tannins, which are responsible for colour and structure.
