How do bees turn watery flower nectar into honey?

Honeybees transform watery flower nectar into honey through a two-part process involving chemical breakdown and moisture reduction.12

Chemical Transformation

As bees collect nectar, they store it in their "honey stomachs," where enzymes begin breaking down the complex sugar sucrose into simpler sugars, specifically fructose and glucose. This process, known as inversion, is essential for the nectar's conversion into honey.12

Moisture Reduction

Nectar typically contains between 50 and 80 percent water, which makes it susceptible to fermentation. To preserve the substance, bees store the nectar in beeswax honeycomb cells and work to reduce the water content to approximately 18 percent. They achieve this by rapidly beating their wings over the filled cells to promote the evaporation of excess moisture. Once the honey reaches the desired consistency, the bees seal the cells with wax to preserve the food source for the colony.132
