How do bees make honey?

Last updated:

Bees make honey by collecting nectar from flowers, storing it in their special honey stomach, and then passing it between bees to break down the complex sugars into simpler ones. They finally deposit the processed nectar into honeycomb cells and fan it with their wings until most of the water evaporates, creating honey.

Nectar Collection

Worker bees fly from flower to flower using their long, tube-shaped tongues to drink nectar. They store the nectar in a special stomach called the honey stomach, which is separate from their digestive stomach. A single bee may visit 50 to 100 flowers during one nectar-gathering trip.

Enzyme Processing and Regurgitation

As the nectar sits in the honey stomach, enzymes like invertase begin breaking down complex sugars into simpler sugars like glucose and fructose. When the bee returns to the hive, it regurgitates the partially processed nectar to another bee. This bee-to-bee transfer continues, with each exchange adding more enzymes and further breaking down the sugars.

Deposition and Storage

After several bees have processed the nectar, it is deposited into hexagonal wax cells in the honeycomb. At this point, the nectar still contains too much water to be considered finished honey. The nectar in the cells is thinner and more liquid than the honey we know.

Water Evaporation

Bees work together to reduce the water content in the nectar. They fan their wings rapidly over the cells, creating air circulation that evaporates excess moisture. This process continues until the water content drops from about 70% in fresh nectar to about 17% in finished honey. Once the moisture level is right, bees seal the cells with beeswax caps called capping.

Why Bees Make Honey

Honey serves as the primary food source for the honeybee colony. Bees rely on honey during winter months and during times when flowers are not in bloom and nectar is scarce. A strong hive needs to store large amounts of honey to survive the winter and feed the colony until spring flowers return.
