A beverage making system that includes a plurality of packs containing
different beverage making ingredients and having different infrared
reflectance spectra in a region thereof. A beverage making apparatus
includes a station for receiving at least one of the packs; a source of
liquid adapted to supply liquid into the at least one pack while the pack
is located at the station; a system controller for controlling the supply
of liquid from the source according to a beverage making program; and an
infrared pack recognition system comprising an infrared light source for
illuminating the region of the pack while it is located at the station.
The apparatus also includes a detector for measuring an intensity of
infrared light reflected from the region and for supplying an output
signal to the system controller, whereby the beverage-making program is
selected by the system controller in response to the output of the
infrared pack recognition system.
