A vacuum-insulated stainless-steel thermos jug, designed for seamless brewing with the Aarke Coffee Maker. Perfectly suited for serving at the table, and keeps your coffee warm without activating the hot plate, thus saving energy. For best results, we recommend brewing 6–10 cups and preheating the Thermal Jug before use. Simply fill it with hot water, close the lid, and let it stand for 5 minutes.
