Off flavored syrup.

[Tom59]

I pulled a couple quarts of last years syrup out. When made, was checked with a hydrometer, bottled at 185/190, Bottled in canning jars properly sealed. Opened them up and they have an odd flavor, hard to describe, best i can can say is almost like its fermented? Theres no mold, light sediment on bottom. Any way of salvaging this or have to chuck it? thanks

You can often make good molded sugar out of it. The extra heat often gets rid of the off flavor.
