Subject: Jiffy pop method of roasting!
 

So far I've all of the traditional manual roasting methods I've tried have produced far better coffee than any mass produced "store" coffee, if not for the fact that they are fresh roasts.  But they are quite inferior to machine roasters that provide two key elements--even, enclosed heat source and tossed beans.

So in my experimentation, I incorporated those two elements by tossing the beans instead of stirring them. Unfortunately this really isn't feasible with typical pots and pans.  So I remembered seeing a cheap ramen pot from a Japanese gift shop, which was featherweight by comparison--a mere 3.5 ounces.

I found the results were highly improved over stirring but tossing them in open air resulted in considerable heat loss during the roast, so it took almost 20 minutes to get to first crack just for 8 ounces of beans.  As you can imagine, 20 minutes of this can be quite labor intensive.     I solved this problem my covering the pot with foil wrap.   The result was incredible, cutting my roast time by 2/3rds and producing incredibly even roasts--on par with drum roasted coffee.

Shortly after first crack, I walk over to the window, remove the foil and pour the beans back and forth between another identical pot until the chaff is all blown away (as well as the smoke).

I have dubbed this the 'jiffy pop" method.  

Here's the result:

You know you may have come upon something here.  You should try getting a real jiffy pop with the expandable aluminum on top and find a way to temporarially remove it, remove the popcorn and its gunk, and replace that with beans.  Then roast as you would regular jiffy pop.  I wonder if the coffee smoke would be cut down due to the expanding aluminum foil? (or does it have holes in the top of it ... can't remember, however it islikely).

A million dollar idea if you could find a way to patent the process for coffee roasting.  Likely you would have issues with jiffy pops likely already patended process, but you never know.  It is a different application.

Well it's not something that I think will make me a millionaire, at least not here in America where coffee is just coffee (to 98% of Americans), and specialty coffee is something that contains 2 shots of espresso and 8 shots of syrup!  Nevertheless getting a patent might actually be worthwhile.  Thanks for the suggestion!

This is really interesting. Do you continue to toss the beans while the foil is in place? It looks like the pan would be pretty full with 8 ounces of beans - have you measured the pan capacity and if so, what is it?

Yes, I toss the beans with the foil on.. the foil eventually bows upward due to the continual bouncing of the beans off the foil.  The pan will accommodate a lb or more but 8 is probably the max I'd want to do at a time..

Are you using the thermometer to judge when to stop the roast or are you still relying on the sound?

Both.. I use the thermometer to control the overall roast profile.   I don't roast too far past 1st crack, so the thermometer becomes more informational than instrumental in the finale, where sight and sound are the primary deciding factors.

Here is a demonstration I made.  In case you can't hear it,  1st crack starts around 4:30, and really takes off at the 5 minute mark.

By the way, please ignore huge mess I made at the end..  It's not optimal but works very well to cool the beans while removing the chaff and cleans up in 30 seconds with my shop vac.  I've since updated my process by keeping the foil on to avoid releasing a plume of smoke in the house (as well as the chaff mess) and do all that out of a window.   If anyone knows of something i can use to remove chaff from a post-roasted batch of beans without making a mess let me know.  I've been toying with a few ideas to do this.
