In a brewing system for coffee, wherein the entire apparatus for brewing is designed for a single batch of brewing and is designed to be disposed of and not reused for a successive batch of brewing subsequent to the initial batch of brewing, in order to preserve the purity of each brew batch brewed with said system and maintaining each successive brew brewed with said brewing system absolutely and completely free of any contaminants from a prior brew made with said brewing system, the improvements comprising: brewing structure having members symmetrical about a geometric central axis thereof; said structure having an upper member, an intermediate member and a lower member; said upper member being symmetrical about said axis; said intermediate member being symmetrical about said axis; said lower member being symmetrical about said axis; relatively raised and relatively lowered portions of the bottom of said intermediate member; said raised and lowered portions being symmetrical about said axis; said upper member having primary liquid flow limiting means controlling the rate of hot water into a chamber formed by the composite of said upper member and said intermediate member; said upper member having means venting gas from said chamber during said flow limited by said primary liquid flow limiting means said intermediate member having a central nub centered on said axis; a filter paper portion in the shape of a circular disc having a central aperture operable to surround said nub and said nub limiting the horizontal translation of said filter paper portion horizontally away from said nub and said filter paper portion being located interiorly of said intermediate member and resting on said upper portion of the bottom of said intermediate member; apertures arrayed symmetrically about said central axis in said bottom portion of said intermediate member and providing secondary liquid flow limiting means limiting the flow rate of brew from said chamber to said lower member; said upper member being of a material selected from the group consisting of: plastic, coated paper, treated paper, foil, and laminated metallic foil; and said intermediate member being of a material selected from the group consisting of: plastic, coated paper, treated paper, foil, and laminated metallic foil.
