Included is the preparation of particulate coffee products with improved particle packing characteristics. Fine coffee particles having particle diameters of less than about 600 micrometers are compacted to a bulk density of from about 0.40 to about 0.70 gm/cc. The resulting coffee products have the isodensity and isobrew solid profiles as shown in FIGS. 1 and 2, respectively, where the bulk density and brew solid values for any ternary particle mixture represented on the graph increases with increased coffee fine fractions therein. The process can also be used to control or increase the bulk density of particulate coffee products thereby eliminating or reducing the need to rely upon roasting means to control bulk density. The compaction operation changes the particle morphology without rupturing the cell walls of the coffee.

[ What is claimed is:] [1.] Particulate roast and ground coffee products with improved particle packing characteristics, which products comprise from about 40% to about 85% noncompacted roast and ground coffee particles having average particle diameters greater than about 600 micrometers, and from about 15% to about 60% compacted roast and ground coffee particles which consist essentially of fine roast and ground coffee particles having a compacted bulk density of from about 0.40 to about 0.70 gm/cc and average particle diameters of less than about 600 micrometers,wherein the coffee products have an isodensity profile as set forth in the FIG. 1 isodensity ternary graph, where bulk density values for any ternary mixture of particles as represented on the graph increase with increased fractions of fine roast and ground coffee particles in said coffee products, andwherein the coffee products have an isobrew solid profile as set forth in the FIG. 2 isobrew solid ternary graph, where brew solid values for any ternary mixture of particles as represented on the graph increase with increased fractions of fine roast and ground coffee particles in said coffee products.
