ABSTRACT OF THE DISCLOSURE This invention involves dispersing coffee extract in relatively warm immiscible liquid refrigerant wherein the temperature of the extract/refrigerant mix is maintained at about 15°F. to the ice point of the extract. This permits the formation of large ice crystals whereby the finished product is darker and more coffee-like in color. Next the temperature of the mix is reduced to below -20 °F. and the frozen extract is separated from the refrigerant and is then freeze-dried.
