"Just pour and taste the difference". With the Metrokane wine aerating pourer you don't need a separate aerator. Simply insert the Rabbit Aerating Pourer into a wine bottle as you would a conventional pourer. When you pour the wine you see and hear aeration happening. When you taste it, you enjoy the enhanced flavor and bouquet of perfectly aerated red wine. The Rabbit Aerating Pourer is the first easy, uncomplicated way to aerate wine. Each aerating pourer separates for hand washing and stores in it's own case.
