Coffee tastes best served hot. If hot coffee is poured into cold porcelain cups, much of the heat is lost. For this reason, professionals use correctly pre-warmed cups as a matter of principle. Jura’s slim, elegant cup warmer is a perfect accessory for automatic speciality coffee machines. The two heating elements keep the cups at a constant temperature of approximately 131°F - perfect for preparing an espresso or cappuccino topped with milk foam.
