6 weeks in the making, but weve now taken the first steps at changing the colour of some coffee beans (specifically, the Peru Ceja de Selva Estate) from green to brown.
First roast yesterday was a dud - currently only using a mixing bowl and spoon, and the cooler weather + older heat-gun meant things went way too slow >
Lessons duly noted, some old carpet was used for insulation around the outside of the bowl, with a makeshift lid over half of the top. These additions were immediately noticeable with popping (what I assume to be first-crack) around ~12 minutes and one or two louder snaps somewhere around the 18-20 minute mark, where the roast was stopped and smoke beginning become noticeable, resulting in the after picture.

Expecting much better results than the first try, although still a little cautious as to what to expect when they hit the grinder tomorrow morning. Still trying to locate a breadmaker, and plan to get the thermocouples shortly to get a feel for temperature (anyone know if they are K-type?).
Next few days Im busy, but hoping to go for round 3 on the weekend 8-)
