One of the main points of confusion when learning about wine is this: when do I decant, and when do I just pop the cork and pour? Typically, many red wines could benefit from a little time, opening up in a glass or decanter, to let the tannins that make a wine taste astringent, mellow out a little bit, and to let the flavors expand with exposure to air. But if you don’t have the time (or the idea of adding a decanter to your cluttered kitchen has you hyperventilating), there are useful tools called aerators that will come to the rescue. Typically held over a wine glass, wine is poured through the device and is softened in seconds. An excellent option is the Flavor Enhancing Wine Aerator from The Sharper Image, available at sharperimage.com, for about $30.
