A filter device adapted to separate immiscible liquids in beverages such as coffee or tea and other consumable material such as soups and gravies is so designed whereby the beverage or other consumable material passes through a special prewetted filter cloth member and the oils or other immiscible organic liquids contained in the consumable material are coalesced and retained upon the surface of the filter cloth member. The special filter cloth member is formed of synthetic fibers having a low moisture regain, provided with a multiplicity of fine interstitial openings and is napped on the upper surface.

The method of removing substantially all of the oils and undesirable oil-like hydrocarbons from brewed coffee or tea comprising the steps of passing liquid brewed coffee or tea from a source thereof onto and through a filter-like device positioned below said source, the filter-like device including a synthetic porous fabric filter-like member formed by adjacent strands of yarn and having opposite exposed surfaces, at least one of said opposite surfaces being napped by brushing and shearing the fibers which form said surface, the fabric which forms said one surface being an upper surface when said filter-like device is being used and being formed of relatively fine denier fiber yarns constructed so as to form intestitial openings between adjacent strands which openings have their largest dimension between 0.15 mm and 0.72 mm (0.006 to 0.028 inch) so as to coalesce and trap oils and oil-like hydrocarbons on said napped under surface and prevent said oils from passing therethrough while permitting the rest of the brewed coffee or tea unrestricted passage therethrough into a container therebelow.
