A device for wort boiling has a wort preheater which is heated by exit vapour and which is located upstream of the boiling and steaming in a brew pan or of a pressure and temperature increase and subsequent let-down of the wort within defined residence times. Downstream of the boiling process, two or more evaporation stages are provided in series, in which an evaporation of the wort right into vacuum takes place. The heat arising during the condensation in the vapour condensers of the individual evaporation stages is transferred to brewing water as coolant, in the direction opposite to that of the wort evaporation, and the brewing water is at the same time heated. The equipment for wort-boiling has at least one sludge separation (20) which is located immediately upstream of the stage (82) at the highest pressure and highest temperature of the stage evaporator (82, 86) for the evaporation of the wort or immediately downstream of the stage (86) thereof at the lowest pressure and lowest temperature and at the same time upstream of the wort cooling (90). <IMAGE>
