Thanks - I'll try again. I'm probably not much use to you as I'm in NZ. I just went around asking at places that said that they roast it. I got funny looks but everyone untried sold me green beans. Eventually I got far back enough in the chain to find the supplier that everyone buys from. The defensive attitude goes away when they know it's for home use, not potentential competitor. The supplier have a taster employed and a list of about 50 coffees that I can buy. The taster is an excellent source of knowledge that can always recommend something new and great.

Tldr: ask your local roaster for some or ask who their supplier is.
