An electrical apparatus useful to prepare a hot beverage from a flavor substance. The flavor substance is prepacked in single serve portions as filter units which include a filter carrier, a filter, a flavor substance and an upper closure. The apparatus has a storage tank for a liquid, a volumetric measurement tank, venting pipes that join the top corners of the volumetric measurement tank with the top section of the storage tank, a heater for the liquid and a shower head. A shut-off valve controls the flow of liquid between the storage tank and the volumetric measurement tank. The heater controls the flow of liquid from the volumetric measurement tank to the shower head. The apparatus allows the liquid to pass from the shower head through the upper closure of the filter unit so that liquid may pass through the flavor substance in the filter to form the beverage.
