Abstract
Abstract Described is a coffee percolator for dispensing individual charges of freshly brewed coffee, which may also be employed, however, for satisfying a temporarily occurring increased demand. To this purpose the percolator is provided with a second outlet for dispensing the coffee into a storage container. In a preferred embodiment, two separate switching means are provided for actuation by the user for dispensing the coffee directly into a serving receptacle or into the storage container. This permits charges of different size to be preselected, so that a greater amount of coffee can be brewed for filling the storage container than would be required for filling a serving receptacle. The storage container is portable and provided with its own outlet, so that it can readily be carried to the site of use.
