Abstract
A flowable roasted and ground coffee product is provided having a median volumetric ('X50') particle size of from 270 to 1100 .mu.m, a density of from 0.5 to 0.7 gm/cc and 30-41% by weight of which extracts when brewed. The product is in the form of aggregates of granular roasted and ground coffee particles having a maximum X50 particle size of 270 .mu.m and is produced by forcing roasted and ground or roasted whole bean coffee through an orifice under conditions of pressure and shear sufficient to grind the coffee and to form the coffee into a dense mass of roasted coffee made up of the granular roasted and ground coffee particles tightly bonded together. The dense mass of roasted coffee is then reground to produce the roasted and ground coffee product which is in the form of aggregates having an X50 particle size in the range of 270-1100 .mu.m, the aggregates being made up of the granular coffee particles.
