When you keep bees it's not that unusual to have a 5 gallon bucket of honey. A strong healthy hive can give 30-80 lbs of honey or more in a year, over and above what they need to keep for the winter. I'm hoping to get me a nice load summer.
What do you do with it?- eat it, sell it, give it to your family and friends, holiday/birthday gifts....it doesn't ever go bad and you can just warm it gently to reliquify it if it crystallizes.
