Refrigerate or not?

[hotwine]

We usually drink half a bottle each evening, and yes, it does help to refrigerate the remainder overnight. We replace the cork with a Vacuvin stopper, pumped several times, and that works fine for preserving the wine until the next evening.
I had been in the habit of simply leaving the re-corked bottle overnight on the kitchen counter, until reprimanded for doing that a few weeks ago by at least one board member; we now enjoy the "leftovers" much more than before.
