I've been roasting on my Deidrich IR-3 for about a year now with wonderful (and sometimes not so wonderful) results. Any IR-3 owners out there want to chime in on what works and what doesn't for different coffees? With a 6 lb. load I'm averaging about 14-15 minute roast times, with 1st crack around 10:30- 12:00 depending on the profile, dumping anywhere from 430-460. Any crazy ideas or suggestions for profile refinements would be splendid! My cupping spoon awaits..
