In this episode we are starting a new episode series about a special kind of CoffeePreneurs which is inventors of new roasting equipment. Even though that particular field is extremely technical and involves a lot of industrial-type thinking it is clear that people succeeding with this is as passionate as any green coffee producer, importer, roaster, barista and consumer!I met with Jonas at Frederiksberg in Copenhagen to sit down and have a chat about his life, early days of making the prototype of the machine as well as the technicalities that makes this roaster special. Also we talked about general coffee roasting theory as well as what can be expected from their upcoming launch of the AiO.
