WineGISNapa Valley wine map: AVAs, wineries and vineyard locations
Napa Valley is both a familiar wine name and an American Viticultural Area. Use the map to understand the smaller named AVAs and how winery addresses relate to the surrounding geography.
Explore this region on the mapRead an AVA as a geographical area
An American Viticultural Area identifies a defined grape-growing region. Napa Valley contains smaller, nested AVAs. These geographical boundaries are not individual vineyard ownership lines or a Burgundy-style quality ranking.
Compare places along the valley and hills
Search for names such as Oakville, Rutherford and Stags Leap District, then compare their locations on the map. Check each detail panel for the meaning and source of its boundary rather than assuming the same thing is represented by every outline.
A winery pin is not a vineyard boundary
A winery or tasting-room address may differ from the land where grapes are grown. WineGIS distinguishes producer locations, vineyard points and reference boundaries. An uncertain or approximate point remains labelled as such; a search result alone does not establish a vineyard's exact position.
How to explore with WineGIS
- Start with the region, then zoom in to compare names and boundaries. Click a mapped feature to read its details and available sources.
- Switch between the base maps or use terrain tools where available. A mapped boundary, vineyard location and winery address describe different things.
- Add your own location markers and optional notes. They stay in your browser until you explicitly share a snapshot.
Coverage and limitations
Not every Napa Valley vineyard has a verified location in WineGIS. Approximate and unresolved locations remain distinct from confirmed information. AVA map layers are references; the official federal descriptions take precedence. Personal markers are your notes, not verified vineyard records.
