Some red wines, such as Beaujolais, are better chilled lightly in high summer and I often ask for an ice bucket when served red wine in a restaurant if served wine at much more than 60 F. But chilling to say 45 F, as one might for a white wine, emphasises the acidity and tannin at the expense of fruit and results in wine that simply doesn't taste as good as it would if it had been at room temperature.
when the rules on serving whine were first introduced ... there was no central heating .... so the average 'room temperature' for red wine was around 8 degrees or so now with the advent of central heating and the increase of the average room temperature red wine should in fact be served chilled
