Good organic/fair trade beans
There is a micro-roaster in the Seattle area, Grounds for Change, that roasts organic, fair trade beans. They make a wonderfully smooth dark roast called Solstice Blend. You can order from them online at
http://www.groundsforchange.com and they'll roast your order fresh for delivery. I have tried their Espresso Blend on my home Krups espresso machine and it was dark without being bitter and had nice crema. They also have a french roasted Nicaraguan that I have not tried yet.
Enjoy!
