I was finishing up extracting my fall honey and I found about 50 gallons of honey that is about 30 years old. (in the basement not my hive). Is there anything that can be done with it and how can I tell if it is safe? Most of it is very dark. and still smells like honey maybe a little like hoarhound or maybe goldenrod. I just hate to see that much honey and have nothing to do with it. It was extracted by my grandfather in his early days of bee keeping, I'm not sure why he is keeping it.
