The Honey Crystallization ProcessAny honey can occur in the crystallized form with the exception of Acacia honey, Chestnut honey and honeydew honeys, which generally tend not to crystallize.Honey crystallization is a natural process that can occur over time. When honey contains more glucose than fructose, it is more likely to crystallize. Crystallization begins when glucose molecules aggregate to form crystals. These crystals diffuse through the honey, giving the solution a thicker, grainier consistency.The speed and extent of crystallization depend on various factors, including temperature and honey composition.Crystallization can take days to weeks to fully develop.
