An apparatus comprises a freeze concentration device forming large ice crystals, a foaming system for coffe extract, a freezer for the foam, and a freeze dryer, there being a source of frozen coffee extract particles provided at the foaming system, for example a granulator after the freezer with a recycle device to the foaming system for fines.
