A coffee brewing device includes a housing for holding ground coffee with at least one wall of the housing being formed from a permeable filtering membrane which permits a flow-through of water. The interior of the housing is vented to the atmosphere through an attached conduit, which can be used as a handle, so as to permit the escape of gases which are generated when the coffee grounds are submerged in a cup of hot water. Baffles which serve to control the extent and direction of gas movement may be positioned in the housing. By such control, the generated gases may be utilized to agitate the coffee grounds to thus get a more complete mixing of the grounds with the water prior to a venting of the gases to the atmosphere. The baffles may be of both a perforated and non-perforated design so as to control gas bubble size and direction of flow.
