You don't need a decanter or 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 the aeration happening. When you taste it, you enjoy the enhanced flavor and bouquet of perfectly aerated red wine. Featuring a sturdy plastic pourer with transparent aerator. Separates for easy cleaning; hand wash. Storage case included. Measures 2.5x2.2x7.6"
