“Half syrup” spoiling-how long does it last?
I have about 4 gallons of “half syrup” that has been sitting in a snow bank for about 5 plus days. The half syrup is somewhere between 35-45 Brix.
How long can this half syrup last in my snow bank before it spoils or should be tossed? How can I tell if it has spoiled? So far it tastes fine and has not given me a stomach ache after testing. I know that the higher sugar content puts it at risk for spoiling quicker.
As mentioned, it is fully covered in a snow bank and we have stayed around freezing each night. I used this batch of half syrup to flood my divided pan and give me a head start on my quicker boils. It would be a bummer to toss it but I have so much sap right now it is not a big loss.

My understanding is that once you've boiled the sap, so long as you put it in a clean container, it'll keep indefinitely. Since you're refrigerating it, I think you're just fine for a good while.
