How do you know your Acacia honey comes from Acacia trees? Or your favourite wildflower honey actually comes from wildflowers? Well traditionally, bee keepers noted down any plant they saw their bees feeding on, but we now know that the honey bee will forage at different plants for different products. So are the bees actually collecting the nectar from the Acacia or are they feeding on the pollen for proteins? Well the pollen actually provides the key. In every spoonful of honey are lots of pollen grains. Each a unique shape and allowing melissopalynologists (people who study the pollen in honey) to determine which plants the bees used to produce this batch of honey.
Since the beginning of honey production, certain honey types have been favored because they taste better, are better for cooking or do not rapidly crystallize. Thus, they are preferred over others, are in high demand and are sold at higher prices.
