1. A method of obtaining an indication about a fat content of milk, wherein at least one liquid droplet is made to fall down on a quantity of the milk, wherein the sound of an event of the liquid droplet hitting a surface of the quantity of the milk is detected so as to obtain an acoustic signal of the event,
wherein the method comprises:
performing an analysis of the acoustic signal by executing a routine thereby to yield an estimation of a value related to the fat content of the milk from the acoustic signal;
wherein the analysis of the acoustic signal involves a determination of a frequency spectrum of the acoustic signal.
