The 37 oz. Bodum Bistro Thermo Jug uses a vacuum to maintain the desired hot and cold temperatures of liquids for extended periods of time. Equipped with an easy-press lid, a simple touch opens the jug and lets the fluids flow. To ensure the maintenance of temperature, the lid closes automatically after each use. Whether it’s used for ice tea in the yard, or simply for keeping hot herbal tea on the kitchen table – the Bistro Thermo Jug serves all purposes and looks elegant doing so.
