Abstract: The method for sorting grain (10) comprises the step of conveying the grain (10) with at least a part of the pericarp, seed-coat or aleuron layer or any combination thereof attached into a colour-sorting device (1). The grain (10) is sorted according to colour into at least a first colour-fraction (11) and at least a second colour-fraction (12). The first colour-fraction (11) or the second colour-fraction (12) is conveyed into a size-sorting device (2). Subsequently, the first colour-fraction (11) or the second colour-fraction (12) conveyed into the size-sorting device (2) is sorted according to size of the grain (10) into a size-accept fraction (13) and a size-reject fraction (14).
