Hey Dave, On my list of things to do a large solar dryer and cooker. In some places locals roast on a Wok shaped pan. I just read that the red beans are picked and hulled, leaving the green inside bean to be planted, coffee can take up to 2.5 months to germinate. That said I'd think a fairly fresh unroasted green bean could be planted. I planted the entire fresh bean. Will have to search around in the jungle, maybe I have some hidden plants. I should have said a shrub rather than a tree, just trying to convey they may be a bit large for AP.
Houston? If you're a coffee lover, it's probably not worth doing. If good coffee could be grown there, plenty of it would be growing already. I think 1500-2000 meters altitude and within 20 degrees or so of the equator is where you need to be, although I may be off a bit. Roasting is easy, a weekly chore and generally we grind by the cup here. It's well worth it. Once you start drinking really good coffee, you can't go back.
I've never had enough beans to try it. maybe a handful of red beans from one 6' plant. but the processing of the beans is labor intensive. labor of love :)
they need to soak(how long?), dry(usually in the sun), shelled, and roasting isn't easy either. got to have the right temp.
the plant is beautiful to grow in its own right and the flowers and cherries/ seeds are viable. I've grown several seedlings and given them away. bought mine from a specialty plant shop for a buck. part sun(under a huge tree) and warm days and cool nights. I'm in Northeast US and just bring it in when temps at night are about 40-45F
