The taste of honey is in the buds of the beholder. There are gourmet
honeys that I think taste terrible, but others love them. I have had
honeydew honey and it is a bit off for my taste. My experience has been
that it also ferments quickly. So it may be the honey you are talking
about.
Fermented honey will have bubbles or foam on the top. It looks like
honey that has been bottled too early and not been allowed to get all
the air out. It will be off tasting and should not be fed back to the
bees since it will cause dysentery. Seems like it will do the same with
people.
