A key indicator of raw honey is its tendency to crystallise over time, resulting in a firmer texture made up of fine crystals. How quickly or slowly honey crystallizes depends on the composition of the honey. Classically, honey is composed of the sugars: glucose and fructose in approximately similar amounts (these proportions may vary depending on the source of the nectar). But there are honeys that contain less glucose than fructose, and crystallize more slowly or over a very long period of time (it can take several years), such as Honeydew honey (Fir, Oak, Pine), as well as Acacia Honey. Whereas honeys that contain more glucose, such as Spring honey, crystallise very quickly within a few weeks of collection.
Additionally raw honey contains pollen and other tiny solids that are natural in the production of honey. These particles act as “starter crystals,” providing something for the sugars to start crystallising around. Crystallisation is a natural process and does not compromise the taste or quality of the honey. In fact, it signifies that the honey is raw, free from added sugars, syrups, and heat treatments.
