The colour of honey varies in shade, depending on the foraging activities of honey bees and other factors. Here we'll compare the different shades of honey, and consider some common questions, such as whether darker honey is healthier, and how the colour of honey is measured.
The colour spectrum of honey ranges from transparent through various shades of amber, to very dark, black or almost black1,2.
The colour of honey can be influenced by a variety of factors including2:
Different species of plant have varying properties that will influence the chemical and mineral composition of the honey. For example, colour is affected by pollen content.
Foraging region and season
Region and season (where and when bees forage) can impact chemical and mineral composition of honey, and in turn, affect the colour of honey.
Storage time can affect the colour of some honey varieties (such as Linden and Acacia honey), making it darker1,2.
Crystallization can make honey turn lighter2.
It seems likely that darker honey might have the edge over lighter coloured honeys in certain respects. In general, research tells us that:
Some honey is certainly described as 'black' or 'nearly black', for example, including in scientific papers:
Meadow sage honey, a unifloral honey made by bees foraging on the plant Salvia pratensis, has been described as: "Black, strong, sage-like odor, liquid, viscous"1.
Fennel honey made from bees foraging on Foeniculum vulgare is described as: "Almost black, strong, caramel odor, liquid, viscous"1.
Scales have been developed to measure and grade the colour of honey.
The Pfund And Lovibond Scales
Joseph Williams Lovibond was an English brewer born in 1833. He developed the world's first practical colorimeter and was the originator of the Degrees Lovibond scale. The system has been used to measure the colour of honey along with the Pfund scale, developed later.
These scales use the terms water white, extra white through to dark amber. This table is from the USDA's document: "United States Standards for Grades of Extracted Honey"
|USDA Color Standards|
|Color Range USDA|
|Color Range Pfund Scales|
|Water White||Honey that is Water White or lighter in color||8 or less||0.0945|
|Extra White||Honey that is darker than Water White, but not darker than Extra White in color.||Over 8 to and|
|White||Honey that is darker than Extra White,|
but not darker than White in color.
|Over 17 to and|
|Extra Light Amber||Honey that is darker than White, but not|
darker than Extra light Amber in color.
|Over 34 to and|
|Light Amber||Honey that is darker than Extra Light Amber|
but not darker than light Amber in color.
|Over 50 to and|
|Amber||Honey that is darker than light Amber,|
but not darker than Amber in color.
|Over 85 to and|
|Dark Amber||Honey that is darker than Amber in color.||Over 114|
Other tools are also being proposed for measuring the colour of honey5.
