AIRI-Wine Switzerland: how visible are the 20 largest Swiss wineries to ChatGPT & co.?

Industry-standard measurement, July 2026: an 8% average AI visibility, 5 of 20 wineries never named at all. The full, reproducible report.

When a customer asks ChatGPT which Swiss wineries they should know, the name of an average top-20 estate comes up in just 8 out of 100 answers — the lowest figure of all five countries measured. 5 of 20 wineries were not named in a single one of the 36 answers, among them established houses such as Schuler St. Jakobskellerei, Château Constellation, Zweifel 1898.

The most visible estate is Jean-René Germanier at 28% — followed by the small but internationally renowned Weingut Donatsch (19%). Striking: the country’s largest producer, Provins, reaches only 17% visibility despite its market leadership, with an AIRI score of 45/100 — its website is hard for AI systems to use.

The ranking

The first two columns show the outcome — how often AI names the estate. The last two show the website side — how well AI systems can read it. The two measurements are independent and often diverge; that divergence is the finding.

AIRI rating by score: Excellent from 80, Good 60–79, Moderate 40–59, Poor 20–39, Critical below 20.

What the AIRI dimensions show

The AIRI average of 67/100 is the best in the series — Swiss websites are technically solid (brand clarity 85/100, crawlability 82/100). What is missing are the machine-readable signals: LLM instructions 29/100, structured data 39/100. Translated: AI is allowed to read these websites but finds no facts there it can cite — and in a small market with little international press there is no second source to compensate. That is exactly why Switzerland comes last on visibility despite a good AIRI score.
