A device and a method of sensing characteristics of a food material and a machine and a method of brewing coffee. The device comprises: a wave source () configured for emitting waves to said food material (), with the wavelength range of said waves comprising a selected near infrared band neighboring a visible band; a detector (), configured for detecting intensities of the waves reflected by said food material; and an analysis module (), configured for determining said characteristics according to the detected intensity of the reflected waves. Preferably, the food material comprises coffee powder, and the characteristics comprise at least any one of: color of the coffee powder (corresponding to the roasting degree of coffee powder); and grind fineness of the coffee powder.

A method of providing an indication as to the amount of milk remaining in a breast during lactation based on a determined fat content of milk that has been expressed from said breast is disclosed. The method of determining said fat content comprises measuring an optical characteristic of milk following expression and by comparing said measured optical characteristic with data representing a corresponding optical characteristic of a sample of milk having a known fat content to determine the fat content of said expressed milk which is indicative of the amount of milk remaining in the breast.
