De Chaunac is a French-American hybrid, bred by crossing two Seibel hybrid selections, developed for cold hardiness and disease resistance rather than vinifera character; it was historically a high-volume red in the eastern United States and Canada. California's record for it is short and closed: six crush vintages, all between 2000 and 2005, in a single district, and nothing since. No California FPS registry entry exists for it either. It reads as a variety that had a brief, minor commercial moment here in the early 2000s and then vanished from the state's plantings.

What is published
Counts describe what this atlas holds for De Chaunac, 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.
