I have extracted honey this spring and for some reason the moisture content is too high. It has started to ferment slightly as it has a slight vinegar smell. Can this honey still be used to make mead? Do I need to do anything to it (ie. heat it?)
If it's capped then it has very low moisture content and you are "all good". Honey is hygroscopic though and it will suck in moisture from the air if you let it ... so there's your problem. You need to seal it or otherwise isolate it from the air as soon as you've extracted it. Particularly, as here, if you live in a humid environment.It was capped and ok when I extracted it. I suspect that since it sat in the bucket in the garage several days before I could bottle it, it drew moisture from the air.
