Red wine needs to breathe to allow it to open up, release its intended aromas, and of course, make it taste better. Vinturi's patent pending design speeds up this process by instantly aerating with ease and convenience. It delivers recognizable improvements immediately: better bouquet, enhanced flavors and smoother finish. Perfect aeration in the time it takes to pour a glass. It couldn't be easier. Comes with a no-drip stand. Made of acrylic. Aerator and stand are dishwasher safe. The glossy, clear acrylic is elegant and clean. But do note that there are two slight fold lines that extend upward from each air hole. These are normal. During manufacturing, material folds around rods and wraps back, and this causes the fold lines.
