Depending on the wine, your mood, what you are eating or not eating, the time of day, the phase of the moon, your age, is the dog whining, your personal tastes, if the wine is in a paper bag and your are on a park bench, it can go either way. Now you know why I voted for the third option.
There is no rule of thumb, just myths. Some wines, like lambruscos taste better when chilled, others like merlots better at room temperature, and white wines always better slightly chilled. In Italy and southern France I found almost everyone
puts a small sugar cube at the bottom of the glass before pouring table wine, in the north I found people heating red wines slightly before serving, adding spices, and a bit of water. In most of France, no one bothered as long as the wine wasn't sour, and then they added honey. No one had worst tastes for wine than the Brits, not even the Irish.
In blind taste tests, connoisseurs couldn't tell the difference between cheap wines and the most expensive. That should tell you something.
Ultimately, wine is not like a cola, and however you enjoy it is fine by me. But then
I like ginger ale warm or at least at room temperature. So what do I know?
I give the grandkids watered wine at formal dinners, and afterwards they act as if they were drunk having consumed one short glass, but then without the watered wine they also do act like they are drunk. There can be no other explanation for the odd things they tend to do.
Now stop hogging the bottle, pass that jug of Gallo, and I don't care what temperature it is.
And remember, Champagne and other sparkling wines were once considered trash wines.
