How does "Fermented" Honey look?

[MoisesFromL.A]

So i found 11 quart jars in my garage probably 5-10 years old. I really have no idea. All of it is dark and crystallized, some have lots of bubbles, some looks layered, and some look like whitish web/ grains of rice??? How do i know whats good?

Fermented honey will not harm you. It just tastes nasty. See how it tastes. Fermented usually has bubbles, but I would think those would have stopped years ago. The "grains of rice" are probably large crystals.

The stuff with bubbles on top might be fermenting. When honey crystallizes the honey remaining on top has a higher moisture content making it able to ferment. We just had about 50 bottles go bad that way.
When extracted the moisture content was very low about 16%. When we re-liquified ours there was some brown stuff on top that might have been the yeast culture.
If you know anyone making mead they might like to have it.
