Moccamaster Glass Carafe Coffee Brewers come in a variety of styles and colors – but what sets them apart is their dual-element system. A powerful copper boiling element ensures water temperature is maintained throughout the entire brewing process between 196°-205°F. After brewing, our independent dual-phase hot-plate element maintains coffee holding temperature between 175°-185°, while never burning. All Moccamaster Glass Carafe Brewers switch off automatically after 100 minutes, for convenience and safety.
