Could you please give a synopsis of the equipment you use, where you got it, and how you roast ... any secrets along the way that you have picked up.
Still searching for that allusive perfect cup of coffee.
After wearing out two iRoast 2 in as many years, moved up to the Behmor 1600 drum roaster. Pro--very quiet, larger batches, no breakable parts. Con--for darker roasts, requires much smaller batches. Difficult to see the roasting progress. However, because it is so quiet, you can easily hear the beans crack. It's still working after two years. Note--if you purchase this one, make sure it comes with the small screen drum. Our original drum had a larger screen diameter, and small peaberry beans frequently got caught in the screen.
Has all information on roasting, beans, grinding, etc. that you need to start.
I have bought from them for years.
