Honey Pollen Density Comparator

Pollen grains per gram, log scale — classified by the Louveaux (1978) 5-class system. Tap any bar for detail. Higher density correlates with darker colour, stronger flavour, and higher antioxidant load.

The Acacia Authentication Gap: With just ~3,000 pollen grains per gram — 90× fewer than chestnut — acacia honey is almost impossible to verify by pollen counting alone. Fraudsters exploit this by blending cheaper honeys without a detectable pollen signature shift. Modern authentication relies on NMR spectroscopy or DNA metabarcoding for reliable acacia origin proof.
