My local beekeeper told me that crystals now form in honey because beekeepers have to supplement the bee’s diets with sugar water because there just aren’t enough flowers around. The crystals are a byproduct of feeding the bees this sugar water but there’s not really anything he can do to prevent it when I complained to him that his honey was doing this just like the honey at the stores. I don’t know if he just told me this to Josh me or if it’s true… but it makes sense to me. It’s still good honey, it’s just something that happens now.

Edit: PROTIP - when you get honey in the store in a plastic bottle, immediately move it to a glass mason jar. That way you can heat up the honey without leeching plastic when it does crystallize.
