Popper Roasting

Submitted by Kirk on Mon, 04/25/2011 - 08:08

I took the plunge and just started roasting this weekend. I ahve read Coffeegeek's post on it. I have heard so many different suggestions about roasting that my head is spinning. It seems that it has just as much to do with personal preference as it does with the equipment. I bought a little popcorn popper from Walmart and am wondering about a few things.

1) My beans keep shooting out of the popper and I am roasting about 90-100 grams already which is a lot more than everyone said I could roast at a time. If I roast less than that, it sprays the beans out into my chaff collecting bowl. Should I roast more than that to keep the "spitting" down? Is my popper just larger than others?

2) How long should I roast? I have heard 3-4 minutes, I have heard 5 minutes, I have heard 8 minutes. I don't want to burn them, but if I pull them off after first crack they seem a little fried. Do you generally pull them off during first crack? Right after?

Thanks!

Tough questions

I have only played a little bit with roasting mostly with a recalled Melita roaster. I read a bunch of the articles on Sweet Marias and that helped some and I am pretty sure there are some popcorn roaster articles on there, makezine, and youtube. Also, some of it has to do with the popper I watched a really good youtube video from the guys at Sweet Marias and they showed some of the things you want to look for.

Sorry I couldn't really help more.

Thanks! That does help, I'll

Thanks! That does help, I'll have to check out those resources. It's been interesting as I have roasted more now since I wrote that post. It's really amazing how different the beans can be! The Ethiopian I roasted last time reacted drastically different than the Mexico, it must have been a denser bean or something because I used less beans for roasting and the popper barely moved them! got a more uneven roast because of that... oh well, it's fun to experiment and find out what works.

Popcorn popper

Kirk - roasting in a popper is both easy and difficult. The idea is to keep the beans moving so they roast a litle more evenly. As such, the thought is to put less weight or bean mass in the popper so they move about freely. Even though doing this seems corect, it is not. This casues the bean mass in the popper to struggle to reach the temps necessary to bring the beans to 1st and 2nd crack. So what do you do?

The key is to have just the right amount in there so the beans can rise in temp based on bean mass and applied heat. I do this by starting the popper then slowly adding beans until the swirling stops and seems like it wants to spin but cannot on its' own. I then put the chute on and lightly shake the popper thus keeping the beans moving around until some of the moisture has left, then the beans will start spinning on their own. Then just a few more shales after a minute or so and then riht at 1c. This method makes sure there is enough bean mass to gain temp rise and not too much so as to burn the beans becasue they are not moving. Also, the corect type of popper is required. In addition, if you are using an extention cord or on a circuit that also has a refridg on the same circuit will create voltage shortages that will effect the roast.

A westbend popery I or II are best. No modifications really necessary. Let me now if this helps some.

Hard Work! :)

interesting. I will have to keep working on it! It's definitely not as easy as I thought it was in the beginning ;)
