An American Viticultural Area is a federally designated wine-growing region — Napa Valley, Willamette Valley, Finger Lakes. The TTB defines them in 27 CFR Part 9, with each AVA's boundary, history, and parent/child relationships buried across decades of rulemaking notices.

This dataset flattens all 340 AVAs into a single CSV. Each row has the official name, alternate names, all states and counties the AVA touches, the establishing date, and the CFR rulemaking author who drafted the current rule. Nested AVAs are linked via parent/child arrays.

AVAs almost never change — new AVAs are established a few times a year and existing ones are amended even less often. The dataset is refreshed when 27 CFR Part 9 is amended.
