I did notice at NOFO yesterday they serve the counter culture coffee and offer it for bulk sale. I reccommend Java Estate. They roast their beans in Hampstead. Much of there buisness comes from phone orders. They do sell their beans at Temtations and Everyday gourmet. It is a local buisness and I believe in supporting the locals when possible.
I am a big fan of Counter Culture, but have you tried Port City Java yet? They roast their beans right there in Wilmington. PCJ has an extensive training program for anyone that sells their coffees; the training center is on Market near downtown. I think they make an excellent cup.
Really, North Carolina is very, very lucky when it comes to bean roasting. There are so many excellent roasters in the state (the aforementioned PCJ and Counter Culture, 8th Sin, Tradewinds, Joe Van Gogh, Larry's Beans, Stockton Graham, Java Estate, Dilworth Coffee, to name a few). Yes, Counter Culture is excellent, but do think about trying PCJ, they really do a nice roast.
