Barrel Aged shelf lives after opened

maybe 2 days. depends how much you care about carbonation / how much it matters to that particular beer.

some big stouts i've enjoyed more the second or third day because the small amount of oxidation probably helped (or i just magically enjoyed it more, who knows).

 

This is kind of like that "How many licks does it take to get to the center of a Tootsie Pop" question, isn't it?

 

I've never run in to this situation.

 

Not very long, should be consumed immediately after opening but I would push to the next day MAX. Oxidation is not very friendly to many beers...

 

I've found this on several occasions as well—a lot of times, lesser stouts (BA or no) that are too bright/young/harsh mellow out or blend a bit after a day open (but corked and refridgerated, of course). I wouldn't do this with every beer, but especially if I have one that I'm just not loving, sometimes I'll do this intentionally to see if it improves. Anyway, to the OP's question, if you care at all about carbonation or flavor, they'll be pretty far gone if you wait longer than two nights.

 

Some version of this thread pops up pretty frequently, and the same question always comes to mind: why would you open a beer that you couldn't drink in one sitting?

Unless you're dealing with a really high ABV growler of barrel aged beer, there's no reason not to just drink it. and if you cracked a really high ABV growler of barrel aged beer without a plan (or friends) in place to consume it, then you deserve to have sub-par beer tomorrow.

 

Barrel aged or not, it doesn't matter once it is opened. Drink it all or share it... it will never be as good the next day.
