I have a commercial porter on tap that I feel I have too cold. When I let it warm up the flavour just bursts out of my mouth, but at the ~43F that it comes out it just tastes like cold carbonated water. I've read, though, that the warmer you store your beer, the shorter the shelf-life. I need this keg to last at least two months. So, is my only recourse to store it cold, and then let it warm up to room temp after pouring? Or are there other solutions?
