Honey is a supersaturated sugar solution, which is to say it holds more sugar than it comfortably can. Glucose is the less soluble of its two sugars, so over time it comes out as crystals while the fructose stays dissolved.
How fast depends on the ratio between them:
- under 1.11 fructose to glucose is the fast band
- 1.11 to 1.33 the medium one
- above 1.33 slow or effectively never
Temperature matters as much. Crystallisation runs fastest at about 14 degrees, and a store held between 10 and 16 will granulate. None of this is spoilage.
