Abstract
Described is a coffee percolator having a coffee meal supply container mounted at an upper portion thereof, in which heating of the coffee meal supply by the heat of the coffee percolator and the resultant loss of volatile aroma substances are avoided. This is accomplished by providing a cooling system effective to cool the bottom of the supply container. In a preferred embodiment the supply container is cooled by means of air aspirated by a fan through an air flow path extending along the bottom of the supply container and subsequently returned to the environmental atmosphere.
