The VacuVin Vacuum Coffee Saver Storage Jar Set with Pump will keep your fresh roasted coffee fresher longer. Once exposed to the air, ground coffee quickly loses its flavour and aroma. The vacuum pump simply extracts the air from the Vacuum Coffee Saver creating a vacuum, so that flavour and aroma of the coffee will be kept in perfect condition. The dark colour of the container protects the coffee from the harmful effects of light. No need to refrigerate or freeze your coffee which can have harmful side effects. A coffee storage jar is a necessary accessory and the VacuVin Vacuum Coffee Saver goes far beyond the standard jar. The perfect gift for the coffee lover.
