Batch size was exactly why I sold my Sono and bought a Hottop. Funny thing is, I'm liking the coffee from the HT so much I'm roasting twice a week, which is more than the capacity of one batch on the Sono.
So maybe batch size wasn't the problem: Maybe the Sono just didn't roast that well? No slam intended - I'm serious.[/quote]
I have a HT and was thinking to go to the Sono but after reading this -- it sounds like I would be going backwards. So, I better look into an expensive drum roaster if I want to upgrade from the HT. Good to hear all the comments, good and not so good.
