More Roasts

Since the HotTop arrived, I’ve gone through four roasts. The first roast (which I’ll call roast zero) was a total failure and I was quite bummed. That is, until I realized that in my excitement and haste, I had forgotten to install the rear filter. Without the rear filter, way too much air was drawn into the roasting chamber by the fan, which quickly stalled and then killed the roast. 250g of baked beans went right into the trash.

Once I figured out what I’d done wrong, the next few roasts went swimmingly. Here’s the data for roast of some of Sweet Maria’s Moka Kadir:
