When stored properly, honey never goes bad. It may crystallize or darken over time, but it will still be safe to eat, although warmth or heat can change honey’s flavor.
It is important to store honey, sealed in air-tight, glass containers (Honey will oxidize if stored in plastic or metal) to prevent it from fermenting. Unclean or wet utensils can also ruin honey, but if stored correctly and used with care, honey will last forever!
