Claim:
1. An apparatus for cold brewing coffee comprising: a filter insert provided as a first component part of a filter assembly, said filter insert having a stainless steel mesh cylindrical side wall extending from a bottom end to a top end of said filter insert, a stainless steel mesh flat bottom perpendicular to and extending continuously across from opposing sides of said mesh cylindrical side wall and a support frame provided in a lattice arrangement along an outer surface periphery of said filter insert for supporting said mesh cylindrical side wall and said mesh flat bottom, wherein said mesh cylindrical side wall and said mesh flat bottom form a first enclosed tubular chamber adapted to receive a measured ratio of a coffee grind and water mixture, and wherein said stainless steel mesh is a woven mesh construction with openings on the order of microns to facilitate a controlled release of contents brewed within said first enclosed tubular chamber; a filter frame provided as a second component part of said filter assembly, said filter frame forming a second enclosed tubular chamber adapted to releasably receive said first enclosed tubular chamber of said filter insert therein, said filter frame having a perforated cylindrical side wall that is spaced radially outward from said mesh cylindrical side wall of said filter insert, a perforated flat bottom perpendicular to and extending continuously across from opposing sides of said perforated cylindrical side wall that is spaced axially outward from said mesh flat bottom of said filter insert and two support bars attached to said perforated flat bottom, wherein a first space is defined between an inner diameter of said filter frame and an outer diameter of said filter insert when said first enclosed tubular chamber of said filter insert is received and arranged coaxially within said second enclosed tubular chamber of said filter frame; and a barrel having an open top end and closed bottom end, said top end of said barrel receiving said filter assembly comprising said coaxial arrangement of said filter insert and said filter frame, and said bottom end of said barrel adapted to support said support bars attached to said flat bottom of said filter frame, wherein a second space is defined between an outer diameter of said filter frame and an inner diameter of said barrel.
