Me and some buddies from work started down this rabbit hole 5 or so years ago. In my garage is full size grill with a 10lb coffee roasting drum. Roasting coffee was one of our most rewarding pastimes. We are all farther from each other now, so it doesn't get used much, but when it did, everyone reaped the rewards of fresh delicious coffee, every day. Theta Ridge is a good place to get green beans from if you are looking in the 10-200lb range, fyi. Vacuum seal the green beans and they will last a while.
