Principal grape varieties

Terroir

• The area is founded on a metamorphic granitic core dating to the Paleozoic, with remnants of Mesozoic calcareous-dolomitic rocks forming the gently rounded hills of the zone.
• Sedimentary and volcanic rocks accumulated over time have been carved by erosion into low, often tabular relief forms rising above the western plains, the latter created by the intersection of scree deposits, alluvial accumulations, and mixed deposits of lagoonal and coastal origin.
• Vineyard soils include Entisols and Inceptisols of varying degrees of development and depth, as well as Alfisols with clay accumulations at depth, some highly evolved with illuvial carbonate hardpans.
• The climate is Mediterranean, with mild, moderately rainy winters and hot, dry summers, with a mean annual rainfall of 500 mm distributed over approximately 55 days concentrated mainly in autumn–winter and spring.
• Winter temperatures rarely fall below zero, with a mean annual minimum of 12°C, while summer temperatures can reach 40°C, with a mean annual maximum of 22°C.

• The area's winemaking tradition dates back at least to the Phoenician-Punic period, in the eighth century BC, when the Phoenicians traded with the Nuragic peoples.
• The grape variety Carignano was introduced during the Spanish period by the Aragonese people, between the fourteenth and fifteenth centuries.
• The most widespread training system is the traditional bush vine (alberello), with variable planting densities of 1.00–2.50 metres between rows and 0.8–1.20 metres within the row.
