ABSTRACT:
To reduce insoluble solids contained in a coffee extract obtained from a countercurrent extraction process, the percolation rate of extraction liquid passing through at least one extraction cell, which is positioned intermediately in the countercurrent cell series between extraction cells containing the least extracted coffee material and the most extracted coffee material, is reduced. The flow of extraction liquid may be increased through an extraction cell in the series downstream from the at least one cell in which the percolation rate is reduced.
