Honey produced in France is also graded but as follows:
Price of White honey - usually Rape (Canola) like Sunflower(golden/
lemon yellow) has the least "respect" due to it being produced in
quantity. Dark honeys such as Sweet Chestnut (Castanea sativa) command a
mid price. Others such as light coloured Lavender higher still, then
Heather/Ling (both being dark)  finishing with specialised honeydews and
pine "honeys", again very dark in colour. This list is only an
indication of how colour may/ may not influence the price.
The classic honey for the French population is "Acacia" (False acacia -
Robinia sp.) - mainly due to it resting in a liquid state over many
months.

So, prices vary according to taste, production levels and blending
ability.
