The Jura glacette complements the glass milk container, keeping the milk cool for up to 2 hours, providing the optimum conditions for enjoying specialty coffees with milk. The glacette keeps the milk fresh and cool without being connected to the power supply. The passive cooling process involves a cooler sleeve which is inserted into and removed from the glacette via the screwable base. Simply store the cooler sleeve in the freezer overnight and in the morning, insert the frozen sleeve into the glacette. The shape of the glacette harmonizes with any JURA coffee machine.
