About Wine Mapper
An independent guide to every licensed winery in the United States.
Where the list comes from
Every winery in the U.S. must hold a federal permit from the Alcohol and Tobacco Tax and Trade Bureau (TTB). Our list starts from TTB's public list of wine producers, last updated November 2, 2026. We show the winery's business name (its trade name when it has one), town, county and state. We don't publish street addresses or the names of individual permit holders.
A permit means a business is licensed to make wine; it doesn't mean it has a tasting room. Some producers sell only online or wholesale, or are open by appointment only. 1,903 listings share a production address with several other brands and are marked shared facility. Always check a winery's website or call before you visit.
Wine regions and maps
Region boundaries come from the UC Davis Library AVA Project, which digitizes the official TTB boundary descriptions and releases them under a CC0 public-domain license. Maps on this site are simplified for speed, and base maps are © OpenStreetMap contributors.
How we match wineries to regions
We place a winery in a region when most of its ZIP code area lies inside that region's boundary. That works well for most regions, but it's approximate: a winery near a boundary may be listed in a neighboring region, and some very small regions show no wineries. Region acreage is calculated from the boundary map and is approximate.
