A coffee milling process comprising the steps of: introducing particles of a roasted coffee precursor into a milling chamber 2; introducing particles of soluble coffee into the milling chamber; jetting a gas into the milling chamber to mobilise the particles of the roasted coffee precursor and soluble coffee. The process produces a milled and blended coffee product by comminuting the particles of the roasted coffee precursor by self-collision with other particles of the roasted coffee precursor and by collision with particles of soluble coffee. Methods for providing freeze-dried and spray-dried coffee are described. A freeze-dried soluble coffee product comprising soluble coffee and ground coffee is also disclosed. |
