Decanting Wine — Wine Decanters
Should you decant — move the wine to a serving container?
Wines deposit sediment as a natural part of aging, some more than others. Decanting the wine can help to separate the clear wine from the sediment. Decanting the wine also introduces air into the wine — letting the wine breathe — releasing the aromas and enhancing flavors, particularly useful for red wines that are a little harsh.
Decanting old wines, just prior to serving, helps to ensure that the wines’ clarity and brilliance are not obscured by any deposit that may have developed over time (pour slowly and avoid decanting the last ounce).
Decant young wines as much as several hours before they are served to give the wine a chance to breath, simulating a stage of development that might normally be acquired after years of aging (pour quickly, even up-ending the bottle – the idea is to expose the wine to air). 
Wine decanter designs vary from the purely functional to the extravagantly decorated, but sometimes unusual design and functionality can go hand-in-hand as in the Orbital Decanter that, when removed from its base, will sit elegantly on your table while a gentle orbital movement increases the breathing of your wine with minimal disturbance.
Some experts prefer to let wine breath in the wine glass, but many find it hard to wait patiently once it's been poured.
