Stored bucket of syrup smells fermented
I had a bucket of syrup in the basement 57 degrees, the bucket was left for a few months when I opened it there was foam on the top and it had a fermented odor. I realize a yeast was introduced somehow. My question is can the syrup be used safely in another form or reheated and canned. Thanks
2022 - 157 taps, 40 gallons of syrup
2021 - 171 taps buckets and tubing, 41 gallons of syrup
2020 - 225 taps bags and tubing, 45 gallons of syrup
2019 - 180 taps buckets and bags, 50 gallons of syrup

Heat it back to 218 or so, and cool it, then taste it. It might be OK or it could be sour. Don't leave syrup in a bucket for more than maybe 3-4 week max, and try to keep it below 40F even then.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
I have made good sugar with fermented syrup. Just have to be careful boiling it as the alcohol can make it foam dramatically...
I know of others that have added fermented syrup to the flue pan while boiling at the end of the season with good results...

Storing syrup in plastic, especially if wasn't properly hot-packed, was low in density and/or has some headspace WILL lead to fermentation. It most likely will never be good as table syrup again, but as suggested, adding a little at a time slowly to the flue pan during a long boil (near the end of a season) might make it OK.

Thank you for the responses.
My main concern was any food borne illness issues, second could it be used in cream or sugar processing or simply becomes bear bait.

Bear bait and nothing more.

I had this happen a few years ago. 2 5g buckets got pushed to the side and forgotten. It was ropey when I discovered and smelled like a brewery when I boiled it separately. Foamed like crazy. We bottled it and I gave it away to family. We called it "cooking syrup" and it was excellent for that purpose.
2010 - barrel stove & a steam table pan. 10 - 12 trees
2011 - same deal as the year before. My son is now hooked along with me.
2012 - Took over the garden shed and set up a Mason 2x3. Hoping to tap 30 - 50 trees. Ended up with 100 taps out.
Finished the season with 16 gallons made
2013- - Purchased a Smokey Lake 2 x 3 Hybrid pan. WOW, what a difference!!
