What temperature do I serve red wine?

Wine Tip # 47 – Service Temperature For Red Wine:

Ambient temperatures in many homes, whether due to the summer heat or winter heating, can push the serving temperature of red wines well above ideal levels. Even temperatures in the very early 20’s that we might find comfortably mild can still exaggerate the impression of alcohol and mask delicate flavours. Reds that have typically high alcohol levels, such as Barossa Shiraz, Châteauneuf-du-Pape and Barolo, can become decidedly spirituous, and lower alcohol wines can tend to look one-dimensional. We recommend opening bottles at a storage temperature of around 14˚C and letting your nose and palate guide you as the wine warms up. If you’re decanting for an extended period, do so in a reasonably cool place or all that careful aeration may be lost in glass of tepid wine. And if that bottle of wine is already 25˚, don’t think twice about popping it in the fridge for five or so to take the edge off.
