I will be sampling my coffee at Nutrition Marketplace, on Swanson Blvd in Clive. They have the best water is Des Moines, a twelve stage filter system that takes up the whole back wall of the store. I've been buying all my pure water from Steve for 10 years. I'll post updates when the dates are set. I've got 13 bags of whole bean coffee there now.
