an open bowl works well also. I can’t wait to be discussing roasting profiles for my Kona, Just after the first crack, the half way between the first and second crack, just my opinion, Cool to roast your own
I don’t go a few days, I go a few hours on a cookie sheet to cool and then place in one of the bags which allows CO2 to escape until ready to grind which will be a day or two to a week.
I attempted to roast outside tonight. The ambient temp out there is around 38F. Roasted it for 25 minutes and I may have missed it, but I don’t think I even heard first crack. The coffee was fairly dark but I did not get the results I was looking for.
Moved the operation back inside again and roasted another batch. About 4.5 minutes until first crack and went to 6 minutes total. This was much closer to what I was looking for. Nice dark roast, much more even. I think I can live with the small amount of smoke from indoor roasting, at least during the winter.
I was definitely under-roasting with my first few batches.
I do find it takes longer outside with colder ambient temps. By the time I reach 465F the smoke is pretty dense so I could never roast inside. Get a thermo/thermocouple and measure the temp, then you won’t have to listen. First is about 400F, second about 440F.
Yeah, I can still smell it this morning. I need an alternative solution. My garage outlets are not conveniently located for the purpose but I guess my next attempt will be to run a short extension cord to the roaster.
I clip it so it will be in the beans measuring the outer bean temp. In my setup when it hits 465F I have the perfect Vienna roast and I then begin to cool.
When it’s cold out I put the hot air popper in a ~3 gallon bucket (the kind you can get from the walmart bakery) and leave the popper top/deflector on so the air is redirected back down to the bottom of the bucket so it recirculates the hot air. Works like a champ.

Hmm, that’s a great idea. I’m going to give that a try. Thanks! It would probably work just as well with a homer bucket, right? Presuming the cord will reach.
