Fifteen months ago I made a blackberry mead that fermented like mad! I used no sulfites. I racked it, aged with oak for three months, and it's been sitting in my 50 degree basement for more than a year and I want to bottle it. The last time I tasted it, it was acidic--I would describe it as "sharp" on the tongue and the gut. Did I leave it on the fruit too long, making it too acidic? Or perhaps, did it just need to age? Will I find it improved after the aging? Is there anything I can to to save it? Help!
