Abstract:

The present invention is a process for making a reduced density roast and ground coffee product comprising the steps of: (a) cracking roasted coffee beans to a size such that about 40% to about 80% are retained in a 6-mesh screen (3. 36 mm, 0. 132 in. ); then (b) normalizing the cracked beans; and then (c) grinding the cracked and normalized beans. The roast and ground coffee product produced by the combination of the three steps has a density between about 0. 24 g/cc and about 0. 41 g/cc. The reduced density roast and ground coffee product has an acceptable non-chaffy appearance. Problems associated with the use of air removal and screening are avoided.
