A coffee package has a filter assembly double folded and enveloped air-tight in a wrapper in a vacuous or inert gas atmosphere. The filter assembly includes a generally rectangular support plate made up of an intermediate portion with an opening for pouring hot water therethrough and a pair of support legs connected with opposite sides of the intermediate portion. The support legs are formed with coactive nipping members adjacent to their edges such that, when the support legs are folded upright relative to the intermediate portion, the nipping members are firmly engagable with the upper edge of a receptacle to support the whole assembly in the raised position for use. A sack of filter paper open at one end is filled with a weighed volume of coffee powder and adhered to the back of the support plate to cover the opening in the support plate. The opening in the support plate may be formed in the production stages of the coffee package or defined by a lid which is removable from the support plate when coffee is to be served.
