Collio is a hilly area of the Friuli Venezia Giulia region, divided between Italy and Slovenia, which extends between the Isonzo river and its right tributary, the Iudrio river, bordered to the south by the Friulian plain and to the north by the hamlets of Mernico, Cobaler and Lasizze. Collio Goriziano, more specifically, includes about 1,500 hectares of vineyards that have large surfaces happily exposed to the sun, ideal for viticulture. The vineyards are located at an altitude that varies from 60 to 270 meters above sea level.
The cultivation of vines in Collio dates back to Roman times, but also continues during the period of domination by the Goths and the Lombards. In the 17th century, the names of the wines produced in Collio began to emerge, among which we find Ribolla and Cividino among the whites and Refosco and Corvino among the reds. Modern viticulture arrived in Collio in the second half of the 19th century. At this time, the prevalence of white grape varieties was already marked, so much so that in the early 1900s approximately 90% of the wine produced in Collio was white and the rest red. After the Second World War, Collio found itself separated by the border between Italy and Yugoslavia, giving rise to two distinct wine-growing areas, Collio Italiano and Brda in the Slovenian part.
