You don’t need nutritional info on pure honey, the standard glasses and labels from the German beekeeper’s association certainly don’t have that info on them, also, you’d need to test batch-wise. They analyse for maximum water and minimum enzyme levels, but not nutritional value that’s basically given by the water content, a bit more or less protein or pollen doesn’t change the values in a way anyone caring about macros would care about: For those intents and purposes honey is pure sugar.
