Schiava Grossa, also known as Vernatsch or Trollinger, is a light-bodied red grape widely planted in South Tyrol and southern Germany for easy-drinking, low-tannin wines. It is a brand-new entrant to California's CDFA reports, appearing in the crush series only in 2024 and 2025, within a single crush district, with volumes so far negligible — never exceeding 3 tons crushed in either year and no price data yet recorded. No bearing acreage has been reported. Its recent appearance suggests a small, just-established planting rather than any developed commercial program.
