What the Hummingbird water is concerned, I always give it another short boil after I added the sugar. I have found that sugar has "dust particles and minute foreign objects" in it. They are very small, but nevertheless, they are there and have made my water bad even in the fridge.(some gray clouds are floating in it, which I strain out with a coffee filter) I now freeze my "water stash" until I need it in those plastic apple sauce containers from Costco. They are great for this.
