Abstract

Processes for controlling strength of an extracted beverage including providing a pseudo packed bed of an extractable beverage material and contacting at least one liquid extraction stream with the pseudo packed bed of beverage material at a selected depth to obtain at least one zone of minimum extraction and at least one zone of maximum extraction. As the depth at which the liquid extraction stream is introduced into the packed bed increases, the zone of minimum extraction increases and the zone of maximum extraction decreases.
