Allowing the wine to "breathe" before drinking it may enhance the taste. There is a bit of disagreement on whether or not this is true, but from what I have seen there is more evidence that aerating a wine does, in fact, help.
I have learned that you don't just pop the cork and let the wine sit for an hour or so to let it breathe. Pouring it straight into the glass also won't do the trick. To really get the best out of the wine you need a good tool. An aerating decanter can be just the thing we need.
