Terroir

• The soils of Collio are flysch in nature, with a lithology distinguished into marly, arenaceous, mixed, and conglomeratic facies, of Eocene and Paleocene origin.
• The vineyards are situated on hillside soils at a mean altitude ranging from 60 to 270 metres above sea level, with an average slope of between 15 and 30%.
• The general aspect of the vineyards is south-facing, with some parcels oriented toward the south-east as well.
• Mean summer temperatures range from 21.5 to 22.5°C and mean winter temperatures are around 4°C, with average annual rainfall of approximately 1,350–1,400 mm.
• The production zone extends between the Isonzo river to the east and the Judrio to the west, bordered to the north by Slovenia, across communes including Cormons, Dolegna del Collio, and San Floriano del Collio.

• In the mid-eighteenth century the Società Agraria Teresiana, through the work of Giacomo Fabricio, promoted the spread of a terraced vine-training system known as roncs, with one row — or sometimes two — per terrace.
• In the second half of the nineteenth century Count Teodoro Latour introduced into Collio prestigious French and German wine-grape varieties to replace local varieties of lesser interest.

• The white wines of Collio display a pale straw colour, sometimes with greenish or golden highlights, and clean, intense fruity aromas with a pleasingly soft palate.
• The red wines of Collio present a bright ruby-red colour, an aroma with a pleasingly delicate herbaceous note, and a flavour of rounded body.

• The distinctive flysch soil type of Collio imparts to its wines a differentiated phenotypic expression in terms of particular aromas and flavours compared with other winegrowing situations in the region.
