DESC: Employing a stainless-steel vacuum carafe instead of a warming plate, this 1,200-watt coffeemaker brews up to ten 5-ounce cups in just 8 minutes for maximum flavor and aroma, and the carafe then keeps the coffee hot for 4 hours. The carafe prevents coffee from turning bitter, as it can when sitting on a warming plate, and doesn't have to remain with the machine for coffee to stay hot. To reduce calcification, Capresso's stainless-steel ThermoBlock system prevents water from contacting aluminum inside the machine.
