Though you might keep a jar of honey for many years, there are proper ways of storing it that will keep its quality and delay crystallization.
You should always store honey at room temperature, out of direct sunlight. Refrigeration is not recommended as it will absorb moisture. Also, exposure to lower temperatures will make the honey crystallize faster.
Honey will not spoil due to a variety of factors including its acidity and lack of water content. These honey properties work together, allowing the delicious treat to be enjoyed forever. The expiration date or best-by-date located on the bottle is primarily used by stores to track the product.
If honey crystallizes, place bottle in warm water until honey returns to its original form. Crystallization is completely natural and does not affect the quality in any way. Do not microwave in its original container. If you choose to microwave, heat at 15-second intervals in a microwave-safe container.
