Why do bees spit out the honey?

Bees collect nectar from flowers and store it in a special stomach designed for that purpose. Various enzymes are added to the nectar to make a fructose and sucrose mixture. When the process is complete, the bee regurgitates the mixture and places it in a cell within the hive. When the mixture has been drained of excess moisture, other bees make a wax cap to place over the stored honey in the cell. It is then ready to be extracted by a beekeeper. Honey is the purest food that can be bought and NEVER goes 'off'. Even though jars of honey in a supermarket will have a 'sell by' date, this is only to abide by food regulations, but the honey will last for ever.
