The color of non-treated honey comes from the botanical variety used by bees: it is the reason why its coloration allows to commercially identify the single type of origin.
Honey's color also tends to darken as it is aging, according to the conservation or the production method used by beekeepers. (for example: use of old beehives, contact with metals, conservation temperature, light exposure, etc.)
The colors' classification are expressed in millimeters (mm) of the Pfund scale, compared to a standard analytical reference scale graduated on glycerol.
