Keep milk chilled at the optimal frothing temperature in this dedicated container. Topped with a stainless steel lid that creates a tight seal, the attractive fluted glass vessel holds milk in the refrigerator until you're ready for a cappuccino, latte or flat white. The container attaches effortlessly to your JURA espresso machine (sold separately) to froth and foam the milk. Use the included black and white adapters to indicate the type of milk.
