16.5% moisture content, not ounces. Honey, by definition, USDA Grade A anyway, is of a moisture content between 16.5% and 18.5%. Less or more, it is still honey, just not Grade A. Over 18.5% moisture content is prone to fermentation. Especially if it picks up some more moisture or starts to crystalize. Which can concentrate the moisture, leading to fermentation.
