Using your Corkcicle Coffee Pour - over is easy. First, place a #2 or #4 filter in the pour - over. Then, add your favorite coffee grounds. Next, slowly pour hot water over the grounds in a circular motion. The double - walled design helps keep the coffee warm during the brewing process. Make sure to place the pour - over on a flat surface so the non - slip silicone bottom can do its job. After use, simply rinse the pour - over with warm water and mild soap. Don't use abrasive cleaners as they can scratch the stainless steel. Let it dry completely before storing it. Enjoy your delicious, freshly brewed coffee!
