[quote=Mr_Turtlehead Macrobrew beers say 30 days but was wondering about homebrews???[/quote]
How can it be good for 30 days when it was crap to start with?
Seriously, that's just marketing BS to get you to buy more beer. I have homebrews that are approaching 10 years old (Belgian Xmas Ale) and get better every year.
Storage conditions are what's critical in keeping beer fresh. Light and heat beddy, beddy bad for beer.
