Claim Text:
1. A process for producing a coffee tablet for use in an automatic drip coffee maker (ADC) comprising: subjecting ground roast coffee to a multi-step compaction process including a pre-compression step having a first compaction pressure, wherein the ground roast coffee is compressed at a first compaction pressure between 10.6 MPa and 63.6 MPa, and a subsequent main compression step having a second compaction pressure, wherein there is a delay period of between 80-900 milliseconds after the pre-compression step and before the subsequent main compression step and no pressure is applied to the ground roast coffee during the delay period, wherein the pre-compression step is carried out at a lower compaction force but in the same compaction die as the subsequent main compression step so as to form an unbroken coffee tablet prior to use, wherein the coffee tablet exhibits a hardness when dry of at least about 40 N (Newtons), a friability when dry of no greater than about 6%, and readily disintegrates when contacted with hot water during brewing in the ADC.
