I have successfully grown, harvested, cured, and consumed my own coffee. Tried just a few cups worth to see if it is worth doing, because there is some work to it. Currently, I have 7 coffee plants and 4 of them are fruiting, and one of them rather heavily.
Here's one branch of many of coffee flowers. Each one of those represents a coffee cherry.
And here is a bit of it freshly roasted. It's quite good. I could actually use it as EDC.
