Triplett Blanc is a UC Davis-bred cross of Colombard and Vernaccia Sarda, developed for high yield and grape concentrate as much as table wine. California's CDFA ledger shows bearing acreage falling from 675 acres to 234 by 2025, concentrated in the Central Valley counties of Fresno, Madera, Merced, and Tulare — exactly where bulk and concentrate production is centered. Crush volumes have been enormous at times, with one year topping 27,000 tons statewide and 2025 alone totaling about 2,054 tons, at prices rarely exceeding $324 a ton. It functions as a bulk-wine grape rather than a varietal one.

What is published
Counts describe what this atlas holds for Triplett Blanc, 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.
