Newb question: I haven't really noticed this before, but my hives, which are two months old, each have funny smell, not a bad smell… sort of reminds me of a winery, sort of ferment like smell, but not sure. Hives are flourishing otherwise, and I'm about to add supers. Any thoughts what the smell means? I have heard it might mean that they are about to swarm… which sort of freaks me out because I need to add supers today, and maybe that's why… they are about 80-90% built up. Thanks again!
