Granulated frozen coffee extract is heated to partially melt the surface of the powder. Porous spray-dried coffee powder is mixed with the heated granulated frozen coffee extract to obtain particles of the frozen coffee extract coated with particles of the porous spray-dried coffee powder. Weight ratio of porous spray-dried coffee powder and heated granulated frozen coffee extract at the mixing step ranges from about 66:33 to about 20:80. Particles of the coated frozen coffee extract are freeze-dried.
