The boundary, as written into law

Every American wine appellation is defined in federal regulations by walking the boundary landmark by landmark. The official description of this one begins:

From the beginning point at the conjuction of the Napa County-Sonoma County line and the Napa County-Lake County line, the boundary runs along: (1) The Napa County-Lake County line; (2) Putah Creek and the western and southern shores of Lake Berryessa; (3) The Napa County-Solano County line; and (4) The Napa County-Sonoma County line to the beginning point.

Boundary traced by the UC Davis Library from the official descriptions in federal regulation, and released under an open licence. Smoothed for manufacturing. Decorative use only, not for legal boundary determination.
