first attempt at roasting with a Poppery II

I discovered another hot air popcorn popper at the thrift store and felt it worthy of the $3 investment. It's a Poppery II and is compact and quiet compared to the Popcorn Pumper.

I immediately roasted four ounces of Moka Kadir. Interestingly, my results were almost identical to the first time I roasted in the Popcorn Pumper. After 15 minutes I shut it down, having produced almost no smoke, no sustained cracking, and at a much lighter roast than I would normally use.

The result for the first shots I pulled were about as originally described. Under-roasted, solvent aftertaste, very little fruit or sweetness, and low aroma. After a day of rest the only change was that the sweetness may have developed a bit and the aroma was improved.

An interesting effect was that the espresso was produced very quickly and with an absolute torrent of foaming crema. This behavior lessened slightly on the second day. I didn't experiment to see how far I'd have to reduce the grind in order to mitigate it, since four ounces (3.2 after roasting) is not much to play with. There may be some underextraction that would account for a bit of the flavor, but I don't think that's the main factor.

I will try again with six ounces to see whether I can get results more like these. However, that quantity is going to be pretty close to jumping out of the top of the roasting chamber. I may need to tip it back slightly. This is a nicer piece of equipment to use, but at this point I don't know whether it can get the job done.

Update: After a few days, no real change. It is not going to improve with age. This is just a bad roast.
