Bear in mind we are talking bottling not kegging as it conditions cold in the keg and is a different beast IME
I find different beers behave differently and the best way is to take notes and replicate. I like trying beers fresh I get a kick out of it. I do find some that will round off better after some tine, and others that will degrade with time.
The only reason that lager lasted so long is I wasn't in the same state with my beer. By memory I think the hallertau was pretty non existent by then.
