Thompson Seedless, known internationally as Sultanina and originally from Central Asia, is above all California's raisin grape — the TTB's approved name pairs both terms directly. Despite that primary use, CDFA's crush records make it one of the most-processed grapes in the state by sheer tonnage: peak-year volumes have topped 567,000 tons crushed statewide, with 2025 alone totaling about 10,721 tons, tracked continuously across nine districts since 2000. Prices have stayed low throughout, never exceeding $600 a ton, reflecting its role as bulk, concentrate, and juice material rather than varietal wine.
