So I've been stuck at home for 2 weeks recovering from COVID. Ran out of coffee (among other thing). Ordered some green so I'd not be out of fresh coffee if run out again. Hadn't roasted in a while. Roasted each of the three types I ordered into second crack. Tomorrow I'll try them drip just to taste the difference, and espresso, which is how I make my coffee regularly. When I used to roast years ago, I found that I liked the coffee better if I let it settle a few days after roasting; but I need my coffee NOW, so tomorrow I grind some. It isn't roasted as dark as it looks in the picture. When I used to roast for drip, my go-to favorite was Guatemalan Antigua, and I also liked Sumatra and Java. Knob on the popper is a dimmer in series with the heating element to lower the heat. Without it, this popper roasted WAY too fast. I made my selections based partially on low price. Not familiar with any of these, so it's a crap shoot.
