Friuli–Venezia Giulia has the highest proportion of white wine of any Italian region. The primary grape variety in this region is Pinot Grigio. Other white varieties that are prevalent in Friuli include the international varieties Chardonnay and Sauvignon Blanc and the native grapes Friulano and Ribolla Gialla.
The largest denomination for both white and red wine in Friuli is Friuli Grave DOC, which lies mostly in the flatlands of the coastal plain. Some of Friuli’s most interesting wines, though, come from the hilly area along the border with Slovenia. In this area are Collio Goriziano DOC—often shortened to Collio—and, to its north, Friuli Colli Orientali DOC. These two denominations produce a wide range of wines, red and white, blends and varietals, from any of a dozen varieties, including Friulano and Ribolla Gialla along with several international varieties.
