Abstract
Two flash evaporation steps are incorporated into a countercurrent extraction process employed to extract coffee. One flash evaporation step is performed upon a first extract obtained from an extraction cell having a temperature of above 150.degree. C., the flash evaporation being performed at a temperature reduced from 150.degree. C. The second flash evaporation step is performed upon a second extract obtained from an extraction cell positioned at least one cell downstream in the series from the cell from which the first extract was obtained, the second flash evaporation being carried out at a temperature higher than the temperature of the first flash evaporation and the product thereof being introduced to a further downstream extraction cell.
