Specific details are scarce, but apparently a custom-designed packaging line was designed for this application. The coffee is freshly roasted, ground, held and degassed, and then filled with a very low residual oxygen content to ensure fresh-tasting coffee.
Each can holds 1.3 oz of ground coffee, which produces 4-6 cups of coffee. Eight cans are combined in a paperboard carton that sells for about $13.99. The can features a ring-pull aluminum top on a steel body and bottom. A full-wrap polypropylene label on each can includes graphics as well as brewing instructions.
