Hey, so i bought a bottle of traditional mead in glastonbury maybe 2 or 3 years ago, drank a quarter or so of the bottle, put lid on, packaged it up when i moved house, lost it, found it today in a box, cant find a use by date on it, was opened once when i got it, i moved house and the bottle has been unopened since then which is roughly 2 or 3 years.....will it be safe to drink???
