A method of fabricating a dissolvable coffee, the method comprising the steps of:
- providing a mold having a cavity, the cavity having an interior surface which forms a shape of the dissolvable coffee;
- filling a liquid coffee concentrate in the cavity of the mold;
- placing the liquid coffee concentrate which was filled in the mold in a freezer to freeze the liquid coffee concentrate from a liquid state in the mold to form a formed and completely frozen liquid coffee concentrate to a solid state in the mold;
- removing the mold from the freezer;
- placing the formed frozen liquid coffee concentrate in a chamber of a freeze drying machine for a prescribed period of time by a freeze dryer machine manufacturer to freeze dry the formed frozen liquid coffee concentrate;
- turning off the freeze drying machine;
- while the freeze drying machine is turned off, leaving the freeze-dried coffee concentrate in the chamber of the freeze drying machine between about one to six hours after a freezing drying process has run its full course so that an outer peripheral portion of the freeze dried coffee has a hardness greater than a hardness of an interior portion of the freeze dried coffee.
