If one knows that he/she is going to finish the wine the following day, then the easiest is just to pour off half the bottle immediately upon opening into a clean, empty half bottle, and vacuvin or recork it, and put in the fridge. Minimal quality loss (sometimes even improving very young, closed wines).
