Terroir

• Flysch-type soils presenting four facies — marly, arenaceous, mixed, and conglomeratic — of Eocene and Paleocene origin.
• The flysch rocks derive from the uplift of ancient seabeds; marine fossils are frequently found in the vineyards.
• Viticulture is exclusively hillside, at elevations between 60 and 270 m above sea level, across approximately 1,500 hectares, with average slopes of 15–30%. (via Wikipedia · CC BY-SA 4.0)
• The Julian Prealps to the north shelter the vineyards from cold northerly winds; the Adriatic coast, approximately 20 km away, moderates thermal variation and creates a temperate microclimate.
• Mean annual rainfall is 1,350–1,400 mm, peaking in October–November; mean summer temperatures range from 21.5 to 22.5 °C, with winter averages around 4 °C.

• Terraced vineyards known as roncs were widely established in the eighteenth century by Giacomo Fabricio to adapt the hillsides to specialised viticulture. (via Wikipedia · CC BY-SA 4.0)
• In the mid-nineteenth century, Teodoro Latour introduced French and German white grape varieties, broadening the varietal heritage of Collio. (via Wikipedia · CC BY-SA 4.0)

• The Eocene–Paleocene flysch (marls and sandstones) breaks down into a granular, free-draining soil, a condition the production regulations identify as ideal for vine quality.
