I have found all of my RAW honey will / has crystalized. The later in the season that I pull the batch , the faster it seems to turn faster. Was all of the honey from the same super / hive and pulled at the same time?
The pollen is the base for the crystallization. Just warm it up and it will return to liquid. DON'T over heat it. I have taken a pot of VERY hot water and put my bottles in it and let it cool. It may take a few tries, but better to go slow then to destroy the richness and benefit of the pollen and honey.
That's my thoughts. Anyone else?
