By "processing", I specifically meant to exclude roasting. As far as I'm aware, coffee beans are generally roasted in the country where they're consumed. Roasted beans don't stay fresh as long as green beans. I meant the processing that converts cherries into dry green beans.

That processing always occurs near the place it was grown; cherries don't keep. The pulp has to be removed. That can be entirely mechanical, or it can be by fermenting. There are different ways of doing the fermenting. Then someone has to pick over the beans, to sort them for quality.

This is just what I've read; I'm no expert, I'm just an interested consumer. And @tsingy, I imagine you've read a lot more than I have; but you seem to have misunderstood my comment.
