How’s the smell? I’ve considered doing this, but have a house full with a wife and 2 kids. I don’t hate the smell, but it’s not exactly enjoyable for all.
Roasting generates a lot of smoke, but if you have a top mounted range vent that exhausts outside, you could probably get away with doing it inside. We have a pop up range hood in an island range and ended up just roasting outside. If you use a cheap air popper, it also blows chaff all over the place, and if a bean falls out onto the floor or something they’re very hot, so you would need to keep kids/pets away.
i've been doing it without ventilation and i'm really surprised how mild it is. it definitely smells for a few hours, but not bad at all. if it's too bad, i open the door for a few minutes or a window while i'm roasting.
i can't recommend it enough! it's super fun, and a whole new domain to learn about :)
