Terroir

• Flysch-type soils with four facies: marnosa, arenaceous, mixed, and conglomeratic, of Eocene and Paleocene origin.
• The flysch rocks derive from the uplift of marine seabeds: marine fossils are frequently found in the vineyards.
• Viticulture exclusively hillside, between 60 and 270 m a.s.l., across approximately 1,500 hectares, with average slopes of 15–30%. (via Wikipedia · CC BY-SA 4.0)
• The Julian Prealps to the north provide shelter from cold northerly winds; the Adriatic coast, approximately 20 km away, moderates thermal variation, creating a temperate microclimate.
• Average annual rainfall 1,350–1,400 mm, with a peak in October–November; average summer temperatures 21.5–22.5 °C, winter temperatures approximately 4 °C.

• Terraced hillsides known as «roncs», widespread in the 18th century through the work of Giacomo Fabricio to adapt the hills to specialized viticulture. (via Wikipedia · CC BY-SA 4.0)
• In the mid-19th century, Teodoro Latour introduced French and German white varieties, broadening the varietal heritage of Collio. (via Wikipedia · CC BY-SA 4.0)

• Flysch-type soils, with marnosa, arenaceous, mixed, and conglomeratic facies of Eocene and Paleocene origin.
• A mild microclimate благодаря the Julian Prealps, which provide shelter from cold winds, and the proximity of the Adriatic coast (approximately 20 km).

• The Eocene–Paleocene flysch (marne + arenarie) breaks down into granular, free-draining soil, a condition the disciplinare identifies as ideal for vine quality.
