I'm one half of EIDOS, and OINOS started as the study material I wanted while working through WSET myself. What bothered me wasn't the difficulty — it was the form. Wine is the most sensory subject there is, and the preparation for it is a grey PDF, a deck of someone else's flashcards, and a map you can't click. You memorise Bordeaux without ever seeing where the Gironde splits. So we built the thing we were missing: an editorial collection rather than a course — three Volumes of written material, an illustrated atlas of regions and grapes, spaced-repetition flashcards, systematic tasting notes and mock exams. Bought once, open for a set period. No subscription — you're studying for an exam, not renting a gym. To be clear about what it isn't: OINOS is independent study material. We're not affiliated with WSET and we don't award qualifications. Three things changed while building it. The atlas taught us the hardest lesson. We started by auto-tracing raster maps and it quietly fell apart — regions bled into their neighbours. We rebuilt it geo-first: real geodata goes through one projection that produces both the drawing and the clickable areas, so what you see and what you touch can never drift apart. We planned a subscription and shipped a one-time purchase. Wine study has an end date, and charging past it felt like a trick. And we gave away more than we meant to. The Reading Room — long-form essays and short notes on wine — is free and needs no account. It was going to be a teaser. It became the part people actually share. The apps for iOS and Android shipped last week; the web has been live longer. Same account, same material, whichever you open.
