1. A method for producing a cold-brew coffee extract, the method comprising the steps of:
(1) adding water to coffee beans to form a suspension;
(2) wet grinding the suspension in multiple steps to provide a suspension having an average particle size less than or equal to 100 μm;
(3) subjecting the suspension of step (2) to one or more separation steps, wherein the suspension of step (2) is separated into at least one liquid phase and a solid phase, the at least one liquid phase comprising coffee aroma, and the solid phase comprising wet coffee grounds; and
(4) further processing at least one liquid phase to provide the cold-brew coffee extract, wherein the temperature of the suspension during steps (1) to (3) does not exceed 47° C.; and wherein the cold-brew coffee extract obtained in step (4) exhibits a residual fat content of 1 wt % to 10 wt % and a dry matter content of 2 wt % to 12 wt %.
