Got a 1 litre bottle of an ESB I bottled last June still sitting in the bottom of the fridge.
That batch started smelling like nail polish remover from early on during the fermentation. As the months have gone by, drinking a bottle every now and again, the smell hasn't improved all that much, still pretty revolting, but the last bottle I drank, about a couple of weeks ago, the flavour was actually getting a bit better. Sweet, sour and bitter but sort of nicely balanced. Crystal clear and a beautiful colour with great head retention and lacing. Looks good in the glass.
That's one brew I haven't shared with many people
