Terroir

• The territory rests on a core of Paleozoic granites and metamorphic rocks, above which rise calcareous-dolomitic sequences of Mesozoic and Eocene age in the Supramonte and the plateau highlands of the Tacchi.
• During the Plio-Pleistocene, episodes of basaltic effusion occurred, today observable as small plateaus near Barisardo, in the locality of Teccu.
• Vineyard soils are often moderately developed Entisols and Inceptisols, shallow to moderately deep, sandy loam to loam in texture, skeleton-rich and frequently sub-acid.
• On alluvial deposits and colluvial slope deposits, more developed vineyard soils are found, showing clay accumulation and reddening, yet still skeleton-rich and fairly deep, classified as Alfisols.
• The climate across much of the production area is warm-temperate, with mild winters especially in the coastal zones and nearly rainless summers, while precipitation is concentrated in autumn and the winter–spring period, averaging around 800 mm annually and reaching 1,000 mm per year in the wetter zones bordering the Gennargentu.
• Beyond the main warm-temperate zone, cooler areas exist above 800 metres elevation in the mountains of the more inland part of Ogliastra.

• Finds in the form of askoid jugs recovered from the nuragic complex of Bau Nuraxi di Triei, dated to around 1000 BC, have been shown by gas-chromatographic analysis to have contained wine.
• An expense ledger from the Vatican Archives dating to the early 1600s records the purchase of white wine from Telavé, in the village of Triei, attesting to the continuity of viticulture in the area.
• The rows are trained on vertical trellises (controspalliera) with Guyot or spur-cordon pruning, while older vineyards and more traditional zones retain bush-vine (alberello) training.
• Cannonau, from which a highly regarded red wine is produced, is the most widely cultivated variety in Ogliastra and the defining variety of the area's winemaking, alongside which around ten minor indigenous white varieties have been identified.
