Natural factors

Soils formed on Oligo-Miocene detrital sediments: marne, calcari, and arenarie in various combinations, with volcanics ranging from tufi to basalts.
The stratigraphic sequences rest to the east on Paleozoic granitic-metamorphic massifs; in the lower areas, Quaternary alluvial terraces extend across the landscape.
Vineyards occupy slopes and older alluvial terraces on entisols, inceptisols, and alfisols, sometimes with high carbonate content.
Rolling or tabular hill relief up to 500–700 m a.s.l., with slopes increasing from south to northeast; the terrain is flatter to the west.
Inland Mediterranean climate: annual rainfall of 500–700 mm concentrated ~80% in autumn and winter; summers with peaks above 40 °C, winters rarely dropping below zero.

Human factors

Vine cultivation documented since the late Neolithic, with amphora finds and Oenotrian evidence at the nuragic sites of Simieri, Turriga, and Monte Luna.
In the Roman period, the Trexenta was already divided into a cereal-growing zone and a zone with a strong viticultural vocation, with recent studies focusing on the recovery of ancient winemaking techniques.
