The brewing device may include a housing (110) and one or more handles (120) for attaching the housing to a beverage container, such as a mug. The handles (120) may be moved between a stored and deployed position. The housing (110) may be porous and include a plurality of perforations (112) on each side. There may be about 70 perforations, with an even number distributed on each side of the housing, and the perforations may have a diameter of about 2.33 mm so as to permit the flow of oils and other elements of coffee which might otherwise be filtered through the housing material. ## Claims ### Claim 1 A brewing device comprising: a housing having two opposed sides and an interior area dimensioned to be capable of holding a brewable substance, the housing substantially composed of a porous material; a handle provided on one of the two opposed sides of the housing, the handle capable of being attached to a beverage container so as to fix the housing at a position within the beverage container; and a plurality of perforations provided on the housing; wherein the handle includes a wing connected to one of the two opposed sides of the housing by an arm, and the wing and arm are capable of being attached over a lip of the beverage container; further comprising a plurality of connecting strips provided on the same one of the two opposed sides of the housing as the handle, and wherein the handle is movable between a stored position, with the wing positioned proximate to the housing and connectable with the connecting strips, and a deployed positioned, with the wing positioned at a distance from the housing and capable of being attached to the beverage container. ### Claim 2 (depends on 1) The brewing device of claim 1, wherein each perforation has a diameter of about 2.33 mm. ### Claim 3 (depends on 1) The brewing device of claim 1 wherein the plurality of perforations comprise between about 30 perforations and about 80 perforations. ### Claim 4 (depends on 3) The brewing device of claim 3 wherein the plurality of perforations include substantially the same number of perforations on each of the at least two sides. ### Claim 5 (depends on 1) The brewing device of claim 1 wherein the plurality of perforations include about 70 perforations. ### Claim 6 (depends on 5) The brewing device of claim 5, wherein the plurality of perforations include substantially the same number of perforations on each of the at least two sides. ### Claim 7 (depends on 1) The brewing device of claim 1 further comprising a second handle including a second wing connected to the other of the two opposed sides of the housing by a second arm, and the second wing and second arm are capable of being attached over the lip of the beverage container. ### Claim 8 (depends on 1) The brewing device of claim 1, wherein the perforations are arranged in rows around the connecting strips. ### Claim 9 (depends on 8) The brewing device of claim 8, wherein the perforations are arranged in two rows collectively forming a “U” shape. ### Claim 10 (depends on 1) The brewing device of claim 1 wherein the plurality of perforations includes about 70 perforations with substantially the same number of perforations provided on each of the at least two sides, and each perforation has a diameter of about 2.33 mm. ### Claim 11 (depends on 10) The brewing device of claim 10 wherein the brewing device further comprises a second handle provided on the other of the two opposed sides of the housing, the handle and second handle movable between a stowed position proximate to the housing and a deployed position at a distance from the housing, the handle and second handle capable of being attached to an upper rim of the beverage container in the deployed position, and the plurality of perforations arranged around the handle and second handle in the stowed position. ### Claim 12 (depends on 10) The brewing device of claim 10 wherein the perforations are arranged in two rows collectively forming a “U” shape, and the perforations are spaced apart on a left side of the “U” shape about 4.5 mm from center to center, on a right side of the “U” shape about 9.5 mm from center to center, and on a bottom side of the “U” shape about 9.5 mm from center to center. ### Claim 13 (depends on 10) The brewing device of claim 10 wherein the brewable substance is coffee having a medium grind. ### Claim 14 A brewing device comprising: a housing having two opposed sides and an interior area dimensioned to be capable of holding a brewable substance, the housing substantially composed of a porous material; a handle provided on one of the two opposed sides of the housing, the handle capable of being attached to a beverage container so as to fix the housing at a position within the beverage container; and a plurality of perforations provided on the housing; wherein the plurality of perforations includes about 70 perforations with substantially the same number of perforations provided on each of the at least two sides, and each perforation has a diameter of about 2.33 mm;
