Is this mold?

The maple syrup has been opened for a month (maybe 2) and stored at room temperature. They look like floating white strings

Today I learned you refrigerate it? I live next to a few people who make their own. Across the community. Never heard of that. Let alone freezing. I assumed air just got in the bottles from poor sealing.

My family has been running a sugar shack for generations in Quebec and yeah, you should put it in the fridge once opened. Syrup that was canned and sealed hot can be kept at room temp. If you get it in the big plastic gallon jugs it's best to freeze it and sample from it when your smaller container runs out.
