Contact

Questions about a specific wine region, a labeling regulation, a grape variety, or the difference between a Winkler heat summation scale and a simple elevation map — this is where those questions land. The contact page covers how to reach the editorial team at International Wine Authority, what response timelines look like, and which subjects fall within the scope of this reference.

Response expectations

The editorial inbox handles substantive questions about wine topics covered across this site — American Viticultural Areas, TTB labeling requirements, winemaking technique, direct-to-consumer shipping law, and the full range of US wine regions. That is the sweet spot.

Response times depend on the nature of the inquiry:

1. Factual corrections and citation disputes — highest priority. If a specific statistic, regulatory citation, or named producer detail is wrong, that matters. Expect a response within 3 business days.
2. Editorial suggestions and content gaps — medium priority. Suggestions to add a topic, expand a region profile, or cover an underrepresented grape variety are welcomed and logged. Response within 7 business days.
3. Partnership and licensing inquiries — reviewed on a rolling basis. Expect an initial acknowledgment within 5 business days and a substantive reply within 10.
4. Press and media requests — handled promptly when the request includes a deadline and a specific topic. Undifferentiated press inquiries may take longer.

What the editorial inbox does not handle: personal legal or medical advice, investment recommendations for specific wine purchases, or dispute resolution between buyers and producers. The wine law and regulation and responsible consumption pages cover foundational information in those areas, but this is a reference site — not a professional services office.

Additional contact options

For questions that are already answered somewhere on the site, the Frequently Asked Questions page covers the most common inquiries about wine terminology, tasting, buying, and regulations. Before sending a message, it is worth a look — the answer may already be there, explained in more detail than a direct reply could provide.

For broad orientation questions — "where do I start if I want to understand US wine production?" or "how does the three-tier system actually work?" — the how it works page and the three-tier distribution system page handle those directly.

Factual corrections that require sourced documentation should reference the specific page URL and include the name of the original source being cited against. Corrections without supporting sources are still reviewed, but they move slower through the queue.

How to reach this office

Email is the primary contact channel. The editorial address is listed in the site footer. Messages sent through that address are read by the editorial team, not routed through an automated triage system. That means a human reads every message — which also means volume affects response time.

When writing in, specificity helps considerably. A message that says "I think something on the California page is wrong" takes longer to resolve than one that says "the Paso Robles AVA elevation range cited on california-wine-regions appears to conflict with the appellation boundary description in the TTB's Federal Register entry from 1983." The more precisely a question is framed, the more precisely it can be answered.

There is no phone number. There is no live chat. This is an editorial operation, not a customer service center — and the absence of real-time contact channels reflects that honestly rather than burying a phone number that nobody answers before the fourth ring.

Service area covered

International Wine Authority covers the United States wine landscape at national scope — all 50 states, with particular depth in the 8 states that account for the majority of bonded winery locations according to the Alcohol and Tobacco Tax and Trade Bureau (TTB). California alone holds more than 4,200 bonded wineries as of TTB's most recent compliance data, which explains why the California section carries considerably more structural detail than, say, a state with 12 licensed producers.

The site covers:

• Wine regions — from established appellations like Napa Valley and Willamette Valley to emerging regions gaining TTB recognition
• Regulation and law — TTB labeling rules, direct shipping law by state, and the mechanics of the three-tier system
• Wine types and varieties — red, white, rosé and sparkling, native American varieties, and dessert and fortified styles
• Industry and career — certifications, sommelier pathways, winery careers, and wine journalism
• Consumer guidance — how to read a label, storage, food pairing, and health considerations

Topics outside US borders — Burgundy appellation law, Spanish DO classification, Italian DOCG hierarchies — fall outside editorial scope. When a cross-reference to an international standard is necessary to explain a US regulation or comparison (the Champagne method in sparkling wine production, for instance), it appears as context, not as primary subject matter. The focus stays domestic and that boundary is deliberate.
