Should I warm wine in the microwave? Although warming wine in the microwave might seem like a "horrible" thing to do it clearly has some practical benefits.

So will the microwave change the aroma of the wine compared to the conventional way or is it  fine to do this**.

** Maybe before the guests arrive
According to Spanish winemaker guru the Marqués de Griñón, you can safely warm a bottle of wine to serving temperature (12ºC-14ºC). Put the microwave at high for two seconds for every ºC you want to raise the temperature.

Edit: I looked up the reference in his book. It says to heat a bottle out of the fridge (where stored after opening) in the microwave for two minutes at low.
