How fast does your honey crystallize?
Typical months until first crystals form at room temperature (14–20 °C) for 19 common varieties, plotted on a log time axis. The number beside each bar is the glucose/water ratio — the single best physical predictor of crystallization speed.
Rule of thumb (Manikis & Thrasivoulou, 2001):
G/W above 2.1 ⇒ crystallizes within weeks. G/W below 1.4 ⇒ often stays liquid indefinitely. Every ~0.2 drop in G/W roughly doubles the time-to-crystallize.
Ranges are peer-reviewed typical values for pure monofloral honey stored at 14–20 °C in a sealed jar. Refrigeration (2–7 °C) accelerates crystallization — glucose solubility is lowest near 14 °C. Crystallized honey is not spoiled; warm the jar in a 35–43 °C water bath for 30–60 minutes to re-liquefy.
