Abstract
A coffee milling process comprising the steps of: a) introducing particles of a roasted coffee precursor into a milling chamber; b) introducing particles of soluble coffee into the milling chamber; c) jetting a gas into the milling chamber to mobilize the particles of the roasted coffee precursor and soluble coffee; d) thereby producing a milled and blended coffee product by comminuting the particles of the roasted coffee precursor by self-collision of the particles of the roasted coffee precursor and by collision of the particles of soluble coffee with the particles of the roasted coffee precursor within the milling chamber. Processes and products incorporating milled and blended coffee products are also described.

A coffee milling process comprising the steps of:
- a) introducing particles of a roasted coffee precursor into a milling chamber;
- b) introducing particles of soluble coffee into the milling chamber;
- c) jetting a gas into the milling chamber to mobilize the particles of the roasted coffee precursor and the particles of the soluble coffee;
- and
- d) producing a milled and blended coffee product by comminuting the particles of the roasted coffee precursor by self-collision of the particles of the roasted coffee precursor and by collision of the particles of soluble coffee with the particles of the roasted coffee precursor within the milling chamber, wherein the comminution results in the milled and blended coffee product having a dry Helos particle size distribution D90 of less than or equal to 40 micron.

- and
- jet-milling the particles of the roasted coffee precursor together with the particles of the soluble coffee within the milling chamber to comminute the particles of the roasted coffee precursor with the particles of the soluble coffee;
- wherein prior to the jet-milling, the roasted coffee precursor has an average particle size of greater than 100 microns and the particles of the soluble coffee have a particle size of between about 100 and about 3500 microns.
