Abstract:
Shown is a method of making a coffee concentrate, and a coffee concentrate obtainable by the method. The method involves primary and secondary extraction, with split tapping of the primary extract into a first and second primary draw off. The extraction is conducted under such conditions as to satisfy a minimum mass transfer Fourier number, and a minimum ratio of the extraction yield of the first primary draw-off to the extraction yield obtained in all extraction sections.
