By Roaster.

Where a cafe gets its beans is the quietest signal it sends, and often the most telling. A room can be styled in a weekend; a roasting relationship takes years. Sorting the guide by bean source is a way of asking the question that matters most — who decided what this coffee would taste like, and how close are they to the cup in front of you.

Three answers cover the Pattaya scene. The in-house roasters control the whole chain, green bean to cup, under one roof — the most direct expression of a coffee philosophy, and Pattaya has more of them than most visitors expect. Partner-roaster cafes work with a named roaster, often in Chiang Mai or Bangkok, and put that relationship on the menu rather than hiding it — a different kind of seriousness, built on a supply chain instead of a roastery. And Thai single origin is less a sourcing model than a statement: a cafe choosing to pour a domestic highland bean beside its imported Ethiopias and letting a customer taste them side by side.

None of the three is automatically better — a careless in-house roast loses to a well-chosen partner bean every time. But the source tells you where a cafe has put its attention. Use these pages to find the kind of coffee operation you want to support, then read the individual entries, where the audit, still in progress for Issue 01, does the rest.
