When I’m buying coffee in a café, I’m disappointed to get it from a coffee dispenser. Therefore, I’d like to tag the avilable coffee making such as dispenser, french press, portafilter and so on.

Who would like to join the efforts in collecting and maintaing the data? What attributes shall be used.

update 2018-09-13: I’ve created a project page to track progress and to discuss data model: https://wiki.openstreetmap.org/wiki/Kaffee-Karte
