What are AVAs?
Official wine regions
American Viticultural Areas are federally designated grape-growing regions with distinctive geographic, geological, and climatic characteristics. When a wine label names an AVA like "Napa Valley" or "Willamette Valley," at least 85% of the grapes must have been grown inside that AVA's boundary.
A single vineyard is often in many AVAs
AVAs overlap freely. A block in Rutherford is also in Napa Valley and North Coast. A block in Carneros may be in Napa Valley and Sonoma Coast and North Coast all at once. Counting which AVAs apply isn't a single lookup — it's a geographic question.
TTB regulation
The Alcohol and Tobacco Tax and Trade Bureau establishes AVA boundaries through formal rulemaking. Each AVA is defined by a specific polygon recorded in the Code of Federal Regulations. As of 2026 there are more than 270 designated AVAs in the United States, with more added each year.
Case 1: Los Carneros has two parents
The Los Carneros AVA straddles the Napa–Sonoma county line. Part of Carneros sits inside Napa Valley AVA. The other part sits inside Sonoma Valley AVA. There is no single "parent" — Carneros has a substantial geographic overlap with two distinct AVAs that aren't parents of each other.
A hierarchical model is forced to pick. Either Carneros is a child of Napa Valley (wrong for Sonoma-side vineyards) or a child of Sonoma Valley (wrong for Napa-side vineyards) or floated up to a shared grandparent (loses the relationship entirely). Every choice misclassifies real blocks.
Case 2: Sonoma Coast cuts across half a dozen siblings
The Sonoma Coast AVA is enormous — roughly 750 square miles — and it geographically overlaps with Russian River Valley, Sonoma Valley, Petaluma Gap, and parts of Northern Sonoma. Those AVAs aren't parents or children of Sonoma Coast. They're peers that happen to share land.
A vineyard in the Sebastopol Hills, for example, can legitimately label its wine under any of Sonoma Coast, Russian River Valley, or Northern Sonoma — provided the 85% rule is met. A tree model can't represent that without picking a "primary" and losing the others.
Case 3: New AVAs like Petaluma Gap redraw the map
AVAs get added, expanded, and occasionally split. Petaluma Gap (approved 2017) carved out a region that previously sat inside Sonoma Coast and Northern Sonoma. Vineyards in that pocket gained a new AVA designation overnight without moving an inch. The "parent" relationships in any hand-maintained hierarchy went stale the day Petaluma Gap was approved.
Software that hard-codes the hierarchy starts producing wrong answers and nobody notices until someone audits a label.
Check label eligibility
AVA designations on a wine label aren't decoration — they're regulated claims with measurable rules. Drop your blend into the free varietal & appellation calculator and watch an interactive varietal × AVA grid light up in real time, showing exactly what the wine can legally be called on the label.

Frequently asked questions
How many AVAs are there in the United States?
As of 2026, the TTB has approved more than 270 AVAs across the United States. New AVAs are added periodically through a public petition and rulemaking process. The current authoritative list is maintained in 27 CFR Part 9.
Can a single vineyard really be in more than one AVA?
Yes — and most are. A block in Rutherford is automatically also in Napa Valley and North Coast. A block in the Sebastopol Hills might be in Sonoma Coast, Russian River Valley, and Northern Sonoma simultaneously. Each containing AVA is a separately valid labeling option, subject to the 85% rule.
What's the difference between an AVA and an appellation?
In US wine law, "appellation of origin" is the umbrella term — it can be a country, state, county, or AVA. AVAs are the most granular appellations available in the US system and the only ones defined by geographic and climatic distinctiveness rather than political boundaries.
Why does the TTB approve new AVAs?
Anyone can petition the TTB to establish a new AVA by submitting evidence that the proposed region has distinguishing geographic, climatic, soil, and historical viticultural characteristics. The process typically takes several years and includes public comment. Petaluma Gap, Van Duzer Corridor, and Tip of the Mitt are recent examples.
How does Crush figure out which AVAs my vineyard is in?
You give Crush GPS coordinates for your vineyard or block — either a pin on the map or a polygon outline. Crush runs a point-in-polygon (or polygon intersection) test against the full TTB AVA dataset and returns every AVA that contains your location. The result is a set, not a single primary AVA.
Can I embed this AVA map on my own website?
Yes — see the Embed this map section above. The embed is free and works on any site that supports an <iframe> tag, including WordPress, Squarespace, Webflow, and most winery website builders.
Track your vineyard AVAs automatically
Crush looks up the full set of AVAs from GPS coordinates and tracks them through every operation from harvest to bottle. No hand-curated hierarchies, no dropped designations.
