@peterjschmidt, I haven't done tests with grain pro, but some of my competitors have and say there is a difference. They prevent 2 of the biggest issues, the bag itself tainting the coffee, imparting it's jute flavor, and maintaining a consistent moisture. That said, if it is a recent arrival and going to be roasted promptly, I don't know how much of an advantage it would provide.
@wahoo, Econocaribe, Dupuy (formerly called Colmar), and ICW are the main warehouses. Importers/ traders themselves don't own the storage facilities. Most of the regular importers should have coffee in at least one of these warehouses. By the way, I miss your shop. I live in IHB Thurs-Sun and we used to come up all the time.
