The production of honey happens with the help of flowers, bees, and other sucking insects without requiring human intervention. The bees gather pollen from the flowers that they thus allow to reproduce and that have adapted their scents and colors to attract them. The insects collect their nectar through their trunks and store it in their crops up to the hive. Other insects (aphids, mealybugs) are involved in the production of honey by feeding on the sap they release on the leaves of the trees in the form of sweet-tasting honeydew, also collected by bees, after digestion. In the hive, the bees mix nectar and honeydew with their saliva and then pass the mixture from crop to crop. As it passes through, the mixture is enriched, transformed, dehydrated, concentrated, and gradually becomes honey. The more the honey contains honeydew, the darker and stronger it is (oak, chestnut honey, etc.); the more nectar it contains, the clearer and sweeter it is.
