Sugar water residue/growth in jars

924 Views 4 Replies 4 Participants Last post by  paulmon
I've never had this black 'growth' in my jars/jugs. I switched from C&H sugar to a much cheaper sugar this year and I have to wonder if that didn't cause this. I am wondering if this is a mold. The 'new' sugar have Contents: Sugar stamped on the bags. Has anyone experienced this?

See it also if not using bleach or apple cider vinegar. Wife feeds humming birds and it will get like that in the fridge if left to long as well.
