But I only roast to City/City Light or Full City in it. For French Roast or above, I use my barbecue drum on a spit out doors. This person/poster seemed to be concerned about money (or stove top) and my Jenn Air Range and stove top are what I started out with. I have never received a complaint from family ever and I usually plan on baking pizza after roasting a few batches of coffee indoors in our kitchen and everyone loves coffee hints/tastes. Although true I did smoke the house out trying to roast French Roast when I first started.
I also just wanted to say I try to write in a humorous way and not be looking down on people who've never home roasted coffee before. I also have a Bemor 1600 Roaster in my shop. Reality is that over the last 5 years my Jenn Air Range Convection Oven is my personal choice even over the Bemor. But my top choice is my barbecue drum roaster or an old 1920's roaster out in the shop. Anyway if I can help somebody learn a new way, when first getting into home roasting my posts will serve their purpose. You see... I was like this person with their questions on convection ovens 5 yrs ago. I couldn't get any answers in online forums, so I had to just experiment with using it and have had fabulous results. Got it down to a science now!

I've been using a convection oven for nearly a year. The coffee is great however the problem that i ran into that ultimately made me get a drum roaster was the chaff removal and the cooling. it took more time to dechaff and cool than it did to roast. It makes a terrible mess.

Also I forgot to add that I preheat the foil or screen I use for roasting and only load the beans into the oven when the temp buzzer goes off and set the timer for 10 minutes. I prefer fine wirre screen and window screen also works great. With temps down around 10*F right now, beans are cooled in seconds tossing them between two pans then laying them out on a pizza screen and just rolling them around to remove the chaff out side that's left. I use a high speed blower for the large drum in the barbeque on the spit held in a rig set to the side of the barbeque. It too cools fairly quickly, but you just can't beat winter outdoors for cooling beans ultra fast in temps around 20*F outside!
I should also emphacise that I use a custom program on my Jenn Air Range convection oven to change and control temps, so that I've found the ideal patern for different roasts that I can't do with any other roasting method I use. The reality is that in roasting coffee you basically have two methods of applying heat to the beans in a consistent way. Either move/stir the beans in the heated air or move the heated air around the beans like in a convection oven. Naturally the less conduction (which is still being applied in a drum to a degree) contact heat the better. That's why I use a fine wire screen where the beans contact very little metal surface area and my roast are very consistent. With custom formulas my coffee beans come out exactly the way I want now. I've got the formula down to 5 to 10 seconds either way before pulling the beans. Removal from the oven takes less than 10 seconds and they're cooled in less than 20 seconds outside to stop the roast! ....it's a science for me now w/ just 3 ft to the outside from the oven! .....it may not be a professional level roaster, but the results definitely are great!
