I had a batch of JAO that lasted 4 years, it was still very good at that age, not the same as it was at 1 year, but some changes are expected when you age. I don't know if I would say it was "Better" but I definitely would not say that it was "Worse" it was still good and very drinkable.
Storage I think is the key, stored well, it will do better than stored poorly.
