I don't understand how it could ferment so quickly. My experience is different. I do have some frames that are about a year old that I have removed and not extracted that have fermented. Is this honey from a previous year or just a few months old. In terms of bubbles they are rather common for me when I fill bottles from my Dadant holding tanks. I have no problem with17.7% moisture content as I look for below 18%. I do try to get it somewhat lower if possible. JW has a good recommendation as he seems to be a good philosopher.
