Coffee roasting in hot air popcorn popper

This popper does about a half cup at a time. The beans expand some and I find that two half cup roasts fit into a ceramic wire bail jar for storage. This is drinkable at this stage, but I take the beans on a bit further to something like a City Roast/City Roast Plus. Photo of the roasted beans coming up. I think frying pan roasts give a somewhat different profile to the same beans.
