Abstract
A drip coffee maker is provides including a means for delaying the release of brewed coffee from the brew basket assembly position in a brew basket housing. The brew basket assembly includes an upper basket portion vertically movably mounted with respect to a lower basket portion. A bias member is interposed between the basket portions, vertically biasing the upper basket portion with respect to the lower basket portion. A basket valve is included in the upper and lower basket portions, and is actuatable between an open and a closed position. A carafe is included, and has a lid portion with a lid aperture therein. The carafe is removably positionable under the brew basket assembly with the lid aperture proximal to the basket valve. The basket valve opens when the weight of the hot water and coffee grounds in the upper basket portion exceeds a threshold weight of the bias members.
