I bought one wine aerator on a whim. It seemed like a perfect - if unnecessary - stocking stuffer, since we're both wine enthusiasts. If you're a serious wine drinker - or shopping for a wine drinker in your life - give this product a try. At $19.99, it's about the price of a decent California Cabernet, and will yield results for decades to come. I could taste a difference between the non-aerated and aerated wine. I plan on picking up a few dozen and giving them out as gifts to my friends.
