Attribution & Rights
The Atlas combines original editorial work with public, open, and third-party reference material.
AVA legal authority
Official American Viticultural Area authority comes from the U.S. Treasury Alcohol and Tobacco Tax and Trade Bureau and 27 CFR Part 9. TTB materials are the controlling legal reference for AVA definitions.
Spatial reference
The Atlas uses the UC Davis Library AVA Digitizing Project as an additional spatial reference. That dataset is published under CC0. Atlas map displays are interpretive visualizations and are not presented as official federal maps.
Independence
The Texas Wine Atlas is independent and is not sponsored, endorsed, certified, or operated by TTB or UC Davis.
Copyright and third-party rights
Copyright © 2026 The Texas Wine Atlas. All rights reserved for original Atlas material, subject to third-party and open-source rights. Third-party names, trademarks, photographs, data, maps, and source material remain the property of their respective owners or licensors.
Evidence and source handling
The Atlas maintains source and evidence records so factual claims, relationships, geography, media, and provenance can be reviewed and attributed rather than silently treated as verified truth.
