Vacuum coffee storage is the ultimate storage solution for both freshly roasted coffee beans, and ground coffee. Once the air is removed from the jars, there is no more oxygen left to degrade the the coffees natural oils and aromas. These vacuum jars come complete with interchangable vacuum pump, or as seperate refills - which are sold without a pump.These VacuVin Coffee Saver vacuum jars are very well built units, and preserve coffee much longer than non-vacuum storage methods. Made from thick - approx 7/32 thick, polycarbonate, which is shatter resistent. The polycarbonate is smoke colored to block UV rays that are harmful to coffees.
The design is simple: a polycarbonate container to hold the beans, a lid to seal it, and a pump to pump the air out of the jar. The lid seals tightly up against the top of the jar with a rugged siliconized gasket. The underside of the lid has a plastic filter covering that should be left in place to prevent food or coffee being sucked up into the pump. The best way to describe the mechanism that maintains the vacuum is... like a whales blow hole, but flattened. Its a one-way valve, the blow hole opens when air is sucked through, but seals tight when after pumping. The vacuum is so tight, its not possible to remove the lid without relieving the pressure. To relieve pressure from the jar, simply squeeze the blow hole, and the lid comes off. No tugging, no pulling, once the vacuum is released, the lid almost falls off by itself.
All parts are removable for easy cleaning, all parts are dishwasher safe. Additional storage units are sold seperately, starter units can be purchased complete with pump and jar.
