COLOUR BY PFUND SCALE
The colour of honey varies naturally, ranging from light yellow to amber, dark amber and black in extreme cases and sometimes even green or red hues. Honey usually darkens with age. Exposure to heat and storage time may affect honey’s colour. The colour of honey can be graded on a continuous scale called the Pfund scale. A Pfund colour grader is a standard amber-coloured glass wedge that goes from light to dark and provides continuous readings over the entire colour range of honey. The honey is placed in a wedge-shaped container and compared to the scale, and the place where the colour matches is measured from one end of the wedge. As per Indian Standard and Agmark requirements, the colour of honey may vary from light to dark brown.
