Mike and others having problems, I posted earlier saying that I had gone through the diagnostic checks on my Alp and that I was going to try another roast. Well, it worked!!! When I was on the phone today with the guy that invented the Alp, I told him that I liked a medium roast, probably what most folks call "City". He suggested that I try a setting of 4 on the unit, listen for 1st crack, go two minutes past 1st crack and then press the "cool" button to start the cool cycle. I followed this advice just a little while ago and the beans turned out beautiful. For those interested, I was roasting 8oz of Sweet Maria's Kenya AB beans. On a setting of 4, the 1st crack occurred at 12 1/2 minutes. I went 2 minutes longer and pressed the "cool" button making the total roast time of 14 1/2 minutes. Had I allowed the unit to continue to its full timed roast, it would have roasted for 17mins 20 seconds which would have been too much for this bean and my liking. I also did this roast on my deck using a 14ga extension cord so I could set the Alp on a card table, watch it and make notes. I guess what I've learned so far is that no matter what setting I choose, it doesn't really mean that much. I still have to listen for 1st crack and time from there depending upon the bean. Anyway, I'm glad my unit isn't broke after all and it's a lot of fun when you see those beans and they look just right.
