Stinky honey

“Help! My bees need a bath!”

“My honey stinks.”

“There’s a foul smell coming from my hive entrance.”

“I have reeky bees.”

“My bees are collecting rancid nectar.”

“My hive smells like my husband’s gym locker.”

Every autumn a large number of beekeepers report stinky honey. The source of the smell is nectar, most probably from plants in the aster family, including goldenrod and small daisy-like flowers that grow in clusters.

When your bees start to dry this nectar into honey the smell can be overwhelming and somewhat startling. It’s just not the odor you expect from your sweet bees.

Although goldenrod, dandelion, and aster honeys are often not favorites, they aren’t terrible, and they taste nothing like the odor they give off. Nevertheless, many beekeepers prefer to let the bees keep the aster honey for themselves.

This actually works quite well since asters are largely fall-flowing plants. Beekeepers can harvest in early fall and then let the bees keep the fall honey for overwintering.

Some beekeepers fear AFB when they smell aster nectar, but the odors are quite different. Aster nectar has been described as musty, musky, funky, rank, moldy, sour, and rancid. AFB has more of a dead animal smell . . . think rotting meat or fly-riddled carcass on the side of the road.

If you are uncertain, look at your capped brood. If your brood is healthy-looking you are probably smelling aster honey. If you see shrunken brood caps, discoloration, holes in the caps, and the brood frames smell like death, then you need to test for AFB.

You are fabulous! I have been talking about the sweaty sock smell of dandelion forage for years and everyone thinks I’m mad! Thank you for mentioning it in your blog.



You are very welcome! Maybe some folks are more sensitive to the smell than others.


My bees smelled like BO and dirty laundry this past summer but I still loves them


Tansy ragwort can be added to the list of poor tasting honey too.



Good point, and it too is in the Asteraceae family.


What a relief to read this!!! I was so nervous with the smell next to our hives..I was pretty sure it was something sinister. Now I see it was those blue flowers around the eastern end of the house. A very different smell and quite puzzling. My wife thought it was the pollen. I am glad its not AFB. Thanks for sharing!



I encountered a different kind of stinky honey today. I think it’s from fermented honey. Longish story short, I pulled off a deep of honey that had been sitting on top of a colony all winter and I found four frames that appeared to be sweating. Fully capped, dark, liquid honey, but wet on the outside — and stinking like a cheap tequila. If I was a honey bee stuck inside a wooden box, I’d get drunk just off the fumes from it. But I figured drunk bees are better than starving bees, so I gave the honey to some other colonies that were short on honey. This is my first time feeding bees what I can only guess is fermented honey. Do you think I did the right thing?

This sounds like a Dear Abby letter.


Dear Stinky,

I can’t imagine that the honey under the caps had turned. Is it possible that the smell came from a few broken or uncapped cells? Or that mold was growing on the moisture that accumulated on the surface of the capped honey? Like slime mold? In any case, the answer is here: “One for the road: bees with a buzz.”


Uh, I hope it isn’t slime mold. It’s seems not unlikely now that you’ve put the thought in my head. I’ll check out the bees in a few days and see how they’re handling it. I don’t mind them getting a little light headed, but slime mold doesn’t sound good. Thanks.



I give them fermented syrup now and then; I just make sure it’s not their only choice. Still, when you think about it, feral swarms must deal with it. Alcohol is a fact of life.

I don’t much about slime mold, but they probably handle that as well.


We just pulled and extracted some of the stinkiest smelly honey we have had and it taste like it smells. My question will the smell or taste ever fade any to where it is edible? From what I have read it’s the musty, BO smell. I guess i just lost 2 gallons of honey. It is just frustrating because we lost all hives last year now back to 8 hives to have this to deal with. I guess it is always something to keep me on my toes.



It sounds like goldenrod or something similar. I don’t think the taste changes much over time, but some people like it. You could always sell it—just let folks have a taste first so they know what they’re getting. Also, you can cook with it. Better yet, save it for your bees for winter stores. They will certainly like it. Extracted honey can be put in a feeder instead of sugar syrup and is better for the bees. If it crystallizes, you can feed it straight from the jar—you don’t even have to take it out. You certainly didn’t lose the two gallons, you just have to put it to different uses.


Thank you. I bought some raw honey, and it tastes musty. If I knew a bee keeper, I would donate it; it tastes that bad. I am glad to know that it will not make me sick.
