Disclosed is a system (100) for in-line channelling of raw milk according to a predicted future coagulation property of the milk. The system includes a milk line (126) configured to provide direct milk flow between a milking station and a plurality of collection points (132A, 132B). A sampling chamber is also provided to receive pulsating milk samples from the milk line. An analyser (124) is provided to determine at least one optical property of a sample of milk flowing through the milk line (126). This optical data is used by a processor (1145) to estimate a future coagulation property that the milk will have after the addition of a coagulant. A controller (1149) receives this estimate from the processor (1145) and directly channels the raw milk in the flow line to one of the plurality of collection points (132A, 132B) in response to the estimated coagulation property.
