Ribolla Gialla

White wine grape · reported 2006–2025

Further reading: VIVC catalog entry

Ribolla Gialla is an Italian variety from Friuli; VIVC lists one parent as unidentified and the other as Heunisch Weiss, the same ancient grape (also called Gouais Blanc) that is a parent of numerous European varieties. It has no bearing acreage reported to CDFA in California, though it has appeared in district crush records since 2006 across 8 districts. It is a high-acid white grape. In California it survives only as scattered, largely unreported plantings.
