We made a batch elderflower mead for the first time...and we plan to bottle it later today as it has been 5 weeks. Up until 3 days ago the elderflowers were floating at the top of the fermentation vessel...but we noted that all have sunk to the bottom with just the majority of the very plumped up raisins floating at the top. Is this to be expected, or when we open it up later to bottle are we going to be disappointed with a batch gone bad?
