Sugar Syrup expiration dates

[VermontHoneyBee]

Hello

I add Honey Bee Healthy to my syrup and have been monitor to see if I see it going bad and so far it does not appear to go bad even if the bees have taken it all in 5 days.  Is there any science of how long it takes for sugar syrup to go bad?

Thanks

You must still have somewhat of a flow going, as my bees are consuming a gallon of 1:1 syrup in about 36 hours.  I have Honey Bee Healthy and Vitamin Bee Healthy in my syrup.

It has to do with pH, innoculation (how clean the water is, the bucket is, the feeder is), how strong the syrup is (2:1 keeps much better), how warm the syrup is (it ferments rapidly up in the 90s and slower as you get colder).   I make 5:3 syrup and add ascorbic acid and it keeps a long time.  When you make 1:1 with no acid it does not keep very long at all.

Are you "emergency" feeding?
If so, what is the scenario?

I am feeding to encourage comb drawing.  My hives are new and I really don't have any frames with comb.

Yeah, I know... short version is "don't do that".
You create false positives which will, not might or could but
*will* foster poor outcomes in expectations both for bees and
yourself in management.
Allowing your bees to govern growth is what sustainable
beekeeping is about. Unless you're in a lab or Alaska feeding for
growth is silliness, inevitably.
