How bad is it to storage beer at 20 to 25 degrees celsius? Unfortunately I don't have a basement or a different room where it's between 10-15 degrees. Since it's summer, the temperature in the house is between 20 and 25 degrees. All of my beers are stored in a closet where it is 23 degrees at the moment. I have 3 year old Orvals, Barleywines, IPAs and some other beers. Is this going to damage the beer? Or shouldn't I worry about it?
According to this non pasturized &lt;45°F (&lt;7.2°C)
And even then a shelf life of 60 - 90 days   

It might be time for a party

Beer Storage

As for wine cooler.  For shelf life the colder the better as long as you don't freeze.
