HI TBro - I would say that the way to go is the beans themselves, which are available from a variety of suppliers, and many boutique roasters, of course I would recommend beans such as the PNG Okapa, also known as Purosa, which are high altitude and shade grown Jasper Coffee stock's the Okapa, as does my roaster, Joshua Bailey, here in Melbourne Where are you based? Your local roaster ought to be able to point you in the right direction Regards, Acg
