Claim:
A cold brew coffee apparatus comprising: (a) a first container having a first container interior volume, a first container bottom surface, and a first container opening remote from said first container bottom surface; (b) a second container having a second container interior volume, a second container bottom surface, and a second container opening remote from said second container surface; (c) a filter comprising a frame supporting a water-permeable barrier, said filter having a filter base and a filter rim, said filter defining a filter interior volume, said filter sized to fit within said first container interior volume through said first container opening; and (d) at least one feature selected from the group consisting of: (i) a middle unit comprised of first and second opposed openings and a closed channel, wherein said first container opening and said second container opening engage to form a water impermeable seal by said first container opening engaging said second opening of said middle unit and said second container opening engaging said first opening of said middle unit; (ii) a gasket associated with said filter rim, said first container bottom surface being adapted to receive said filter rim, said filter rim and said first container bottom surface forming a seal therebetween and securing said filter within the first container; and (iii) a gasket associated with said filter rim, said first container bottom surface having a cylindrical depression for mating with said filter rim, said filter rim and said cylindrical depression forming a seal therebetween and securing said filter within the first container; wherein said filter is positionable within said first container so that said filter rim attaches to said first container bottom surface to divide said filter interior volume from the remainder of said first container interior volume; wherein said first container and said second container are capable of forming said water impermeable seal between said first container opening and said second container opening; whereby cold brew infusion occurs when water in said first container interior volume passes through said water-permeable barrier and soaks coffee grounds within said filter interior volume to form a soluble coffee extract.
