If you're looking to properly aerate some red wine, a decanter will work just fine, but if you don't have a decanter, and you want to get that party juice ready right away, the Vinaerator and it's wine-whipping turbine might be able to help you out.
The Vinaerator not only uses its turbine to expose your beverage to an approrpiate amount of air right as you pour it, but it also seals off the bottle when not in use, and performs double duty as a wine stopper. So if you're some hybrid wine-snob alcoholic who demands your wine be properly aerated and properly aerated right now god damn it, this could be right up your alley. You can pick it up at Amazon for $40, or Walmart for $20, and then get to drinkin'. [The Green Head]
