Do any of you make mead? I have been making some meads for a few years now and would love to swap ideas.
This was almost certainly an introduction of a foreign yeast, possibly airborne but probably on a utensil, in your carboy, mixing pail, etc.. If you are not absolutely scrupulous about sanitation and keeping the right level of water in your airlock, undesirable yeasts can get in there.It was something in between bad mead and vinegar, tasted sweet and sower at the same time, but in an unpleasant way.
