Refosco

Red wine grape · reported 2000–2025

Further reading: UC Davis Foundation Plant Services

Refosco is associated with Friuli in northeastern Italy, though the atlas carries no confirmed origin record for it. It has no bearing acreage reported to CDFA in California, despite a long thin trail in district crush data: 182 district-years across 11 crush districts spanning all 26 tracked crop years. It is a deeply colored, high-acid red. In California it remains a minor, largely unreported planting with a long but sparse data history.

What is published

Counts describe what this atlas holds for Refosco, not what California grows. A zero is a published answer: it means the source names the grape and reports nothing under it, or does not name it at all.
