I have looked around the site and have not found this question so if it's here, sorry!
It seems to me that the first few weeks I am drinking my beers they taste really good. Maybe the first 2.5 gal or so. Then the flavors start to change. The beer is not as good as it was. I usually put a case or so of each beer, in the fridge at a time. Could keeping them cold for long periods of time make the flavors change? Or could I just be tired of that particular beer after awhile? That seems more likely but I thought I'd ask. If it is the fridge thing, then I'll quit putting so many in at once.
