Sand, silt and clay, against every other appellation
Loam
44% sand · 34% silt · 22% clay
Sandier than 58% of California appellations and clayier than 49%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 24% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.

Producers
A curated roster, not a census — only source-verified entries appear, 2772 published across the atlas.
The roster places a producer in the appellation it names, never in a county — a winery’s address is a street in an AVA, and filing it under the county would be a claim about which of an AVA’s counties it sits in. So this region has no roster of its own, and 1 producers are entered in the appellations within it:
