and the plot thickens....is it possible for a hydrometer to go bad???
My hibiscus mead, which was made on the same day, has been happily fermenting(or so I thought) in the same closet as my bochet. It formed a krausen on top and the airlock was bubbling away, so I hadn't bothered to pull a gravity reading until today. It's been about a week and I just checked it and it only dropped 1 point

Every sample I've pulled from the bochet, and now the hibiscus, has read a temp of 66F, with the yeast tolerances listed at 59-80, I don't think that's my issue, but am wondering if it would hurt to bring them upstairs for a bit to see what happens at a slightly warmer temp.
