Styles

Natural factors

Granitoid rocks formed in the Paleozoic (~300 Ma) in a deep magma chamber, later exposed by erosion: the structural backbone of the Sardo-Corsican tectonic block.
The granitic landscape is dotted with tors, inselbergs, and tafoni smoothed by wind and water, with niches historically used as human shelters.
Soils ranging from weakly to moderately developed (entisols and inceptisols), with a sandy-loam texture, low carbonate content, sub-acid to acid reaction, and low CEC.
Xeric soil moisture regime: prolonged summer water deficit and strong winter surplus, particularly around the Limbara massif.

Human factors

Paleozoic granitic soils (~300 Ma), weakly developed, sandy, acidic, and carbonate-free, with abundant coarse skeletal material.
Intense winds throughout the year across a zone extending from the coast to 500 m elevation, with a prolonged summer water deficit (xeric moisture regime).

Product characteristics

Acidic sandy soils derived from Paleozoic granites: low carbonates, sandy-loam texture, and high permeability — a direct imprint on the mineral profile of the wines.
High annual wind exposure and prolonged summer water deficit shape wines from grapes grown under controlled water stress.

Terroir / wine link

The sandy, acidic, carbonate-poor granitic soils of Gallura impart to the wine the character of an ancient (300 Ma), highly draining substrate.
