SWP stands for Swiss Water Process. This is a completely chemical free process that guarantees the purity of the coffee and does not use harsh chemicals as used in other kinds of decaf coffees. It is a special blend established by our importer in Seattle and processed at the Vancouver, BC Swiss Water plant. Never had a decaf you could actually drink? Try this one! You will be pleasantly surprised at the smoothness of this dark roast. CLICK to email order, or call 541-728-7955. Back to STORE.
