Petite Sirah in California is, by DNA, mostly Durif, a French cross once mistaken for true Syrah and adopted here under its old California name; its registry identity maps to more than one cataloged variety, reflecting that tangled history. The state has embraced it commercially: bearing acreage grew more than four-fold, from 2,494 acres in 2000 to 11,008 acres in the latest report, spread across 40 counties with five grower tech sheets on file. It is known for deep color, dense tannin, and dark fruit, made both as a standalone varietal and as a blending component for structure.

What is published
Counts describe what this atlas holds for Petite Sirah, 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.

5 wines from 1 producer, each read from that producer’s own tech sheet and linked to it. No average is shown, and none should be computed from these. Wineries that publish tech sheets are selected by their own marketing departments, so a mean across them describes publishing habits rather than a grape.
