Abstract

In making coffee extracts the difficultly condensable aromatic constituents of coffee vapours are incorporated by scrubbing these vapours with cold, concentrated coffee extract. In carrying out the process, ground roasted coffee is extracted with hot or boiling water in a closed system to produce the coffee extract. This is concentrated and the vapours produced drawn off, cooled and scrubbed with the cooled concentrated extract.
