Very cool...I wish I kept my old hot air popper so I could give it a try.
I threw away the two air pop makers we had a couple years ago. But I ran out to the local SA and bought one for 3 bucks.
I have an old West Bend "The Poppery" hot air popper. I've recently noticed it seems to have quite a following with people roasting coffee beans. Where do you get the green beans? I suppose they cost more than roasted beans. How do you know when the beans are properly roasted?
There are a bunch of sellers on eBay and it is not as expensive as roasted beans. I was lucky enough to visit my daughter this weekend in the U.P. of Michigan where she goes to college. It is a very small town, Marquette, and very hippy-fied. I walked into the Dead River coffee shop and in the foyer, there were burlap sacks of green beans. I talked to the owner, a friend of my daughter, and he said he would sell what ever I wanted by the pound for $1.50 a pound. So she will be bring home beans when she visits.
He is what the master (cable guy) taught me and I confirmed with my own batch.
1. after a bit of roasting in the pop corn maker, there is a "first crack" that sounds like a higher pitch version of pop corn popping. then that calms down
2. a while later, there is a plume of smoke.
3. then the "second crack" which has a higher pitch sound than the First Crack, but are so close together it sounds like a sizzle/cracking sound.
4. At this point is where you determine the darkness of the roast.
light roast = turn it off just as soon as you hear the Second Crack.
Medium roast = turn it off in the middle of the Second Crack.
dark roast = turn it off at the end of the Second Crack.
Here is one thing that I never thought about: The darker the roast, the less the cafene (SP). When it roasts, same of the caffene burns off....I did not know that before.
This is important to me because caffene gives me heart palatations so I can't take in that much during the day.
They actually taste better if they are allowed to off gas for a couple of days.
I did not know that. I have noticed that the beans get oily looking after a couple days.
