Hi all, so I've got about a half full corny keg of IPA on tap, that I want to swap out with something new to have ready for some guests in the next few weeks. Any ill effects to the IPA if I were to take the half-full keg out of the keezer, and let sit at room temp for let's say a month or so, while the new one's on tap? Thanks in advance!
You can figure that staling reactions go about 2-3 times faster for each increase of 10 degrees celcius (18F). Let's say your keezer is at 4C (39F) and your room temp is 24C (75F). You can figure that a month at 75F will age the beer equivalent to about 4-9 months at 39F.
There are plenty of styles I'd be comfortable doing this with, but IPA is not one of them. Good decision!
