I drink coffee. I wouldn't call myself and advid drinker of the stuff, but I have my coffee pot on a timer and a batch is waiting for me every morning (assuming I remembered to clean it and put fresh grounds in).
It sounds interesting, but i don't think I have the climate for it. I understand that coffee beans like to grow in tropic and subtropic climates.. even indoors that is not possible 3/4 of the year.
You also have to learn the art of roasting the beans. Which I imagine wouldn't be hard, but would be an art all in itself.
... well, there's my useless post of the day. Let us know how it turns out!!
