Beschreibung
Zusammenfassung:	The present invention pertains to a brewing filter apparatus capable of preparing foam, froth, or creme, particularly for coffee beverages, under low pressure. The apparatus can operate at pressures below 15 bar and as low as 1-3 bar. The apparatus comprises a mesh cover, coarse filter, fine filter, large O-ring, coffee container, small O-ring, and foam maker having two opposing holes. The holes have a diameter in the range of 0.3 to 1 mm. The creme is created by the turbulent contacting of two opposing jets of coffee, which enter the foam maker through the two opposing holes. To further increase agitation and the surface area for contact, a stainless steel wire mesh may be situated in the center of the foam maker directly in the path of and in between the opposing jets of coffee to facilitate the formation of more creme.
