Collio or Collio Goriziano is a qualitatively important, predominantly white wine, doc zone on the north eastern border of Italy with Slovenia. Collio did much in the early 1970s to increase Italians’ confidence in their ability to make fine white wine.
Collio, a corruption of the Italian word for hills (see colli), is in the province of Gorizia (hence Colli Goriziano). Half of what was once a single wine zone was annexed in 1918 by Italy, with the border running straight through vineyards. The other half is now known as Goriška Brda (see slovenia).
