In the Dec 07 Zymurgy Charlie Papazian reviewed bottles of homebrew going back to the first AHC competition that he had stored, and none of them went bad, some had not held up but most of them he felt were awesome...We're talking over 20 years worth of beers.
This is a great thread about one of our guys tasting 4-5 years of his stored brew.
Beer's like wine, a lot of them improve with age....That's why stone has "vertical epic" with vintage, and people have vertical tasting parties
I made a beer that won't even be opened before 5 years go by on . http://www.homebrewtalk.com/f12/help...recipe-195096/
The first beer I brewed was a sweet stout. And I got 3 years out of it. But I didn't put any more bottles aside to see.
