Natural factors
- Calcareous, anhydritic, and gypseous soils on the hills (mean elevation 128 m, slope 11%); alluvial and sandy deposits in southern Capalbio (97 m, 2%).
- Monte Argentario and Isola del Giglio rest on a granitic pluton with serpentines, calcari, and scisti; mean elevations around 250 m with steep slopes.
- Mediterranean climate with prolonged spring-summer aridity, minimum rainfall between the first and third decade of July; 630 mm/year.
- Huglin Index between 2,300 and 2,500 units; mean temperature ~16 °C; peak rainfall in November.
Human factors
- The vine has been cultivated in the area since Etruscan, Greek, and Roman times: stone palmenti for treading grapes carved into the rock on Isola del Giglio, pithoi for wine storage discovered at Marsiliana.
- Ansonica requires intense sunlight and dry summers; the disciplinare records minimal precipitation between July and August with prolonged aridity beginning as early as spring.
Terroir / wine link
- Prolonged summer aridity and the winds (Scirocco, briny Libeccio, dry Maestrale) intensify water stress—a condition Ansonica demands in order to ripen properly.
