I wonder if there is such thing as unpleasant honey?
I pulled some goldenrod honey (I think it was) last fall that was not pleasant. Some of it tasted okay, but a couple frames didn't seem right. Maybe it fermented or something, because I let it sit in the super for about a week before extracting it. Anyhow, when I blended them together, the whole batch went weird. It had a really "gamey" aftertaste and bite to it. I ended up feeding it back to the bees.
The spring honey this year was excellent, smooth and full bodied, and it smelled like the Bidens we grew in the greenhouse. Those were the bees' favorite flowers this year; they would attack each plant by the hundreds. It was really good honey.
