I have my new with and my Chocolate pale in the keg now and love them both. I always drink the beers way to quick to fully appreciate the aging flavor. So my question is: If I fill my growler with beer and seal it well, will it stay carbonated? I have heard of people bottling from their keg and saying it gets flat faster. If it does stay carbonated, should I keep it at 42 deg, the serving temp of my beer, or should I bring it back to room temp and let it age?
