White vinegar will remain stable as its 5% and distilled to be as pure as can be. Not much can survive in a vinegar as to bacteria and mold.

Is it just me, or do pickles made with 1/2 water 1/2 vinegar solution get less vinegary after a few years? We had a batch that were made with a 7+% cider vinegar one year, that would peel paint. Two years later, they were fine. Or, it might just be my deteriorating taste buds.

Taste buds do go bad as you get older. As to the 7% vinegar, wow, a bit strong! The cukes do tend to leech out their water, so it will dilute the vinegar a little.
