ABSTRACT OF THE DISCLOSURE An improved and optimized design for a universal infusion coffee filter pack designed to fit and provide for consistent brewing of quality coffee in a variety of American style and European style coffeemakers. The infusion coffee pack comprises a first circular piece of filter paper, having its surface area stretched and increased by at least 3% to form a rounded pocket, and sealed to a second circular piece of filter paper to a form a substantially one half inch sealed flange therearound. A metered quantity of coffee grounds is sealed within the rounded pocket, and is provided with a head space of substantially fifty percent or greater of the volume within the rounded coffee pocket. The first and second circular pieces of filter paper each preferably have a diameter of approximately five inches, and are filled with a metered amount of ground coffee to brew five cups of water. In this optimized design, the presence of the one half inch flange in combination with the increased surface area caused by stretching results in a brewed coffee having an increase in soluble solids extraction and a decrease in the standard deviation of soluble solids extraction.
