I’ve been using a Capresso conical burr grinder for years. It works great, but I have to deal with grounds accummulating due to static and the lack of verticality in it’s design. We like dark roast, where the expressed oils don’t help, but I happily do the extra work because the coffee is stellar.
When we are on the road and need to grind coffee, I use a Hario Ceramic grinder. I took the handle off, replacing it with a nut. Then I use a rechargeable electric screwdriver fitted with a socket. Doing the grinding by hand is far too much work! Ritual is ok, but tedium isn’t!
But buying unknown coffee beans on the road is something I try to avoid. So much of the coffee we end up with is not fresh, or just poor quality, or we just don’t like it. That’s why I prefer to grind our favorite beans at home, measure and vacuum seal, and freeze.
