"The distinctly-shaped Vintorio aerator pourer features an air intake tube system centered around Bernoulli’s principle—the idea that increasing the speed at which a fluid moves directly translates to a decrease in its pressure. The pourer's large aerating chamber, ribbed and tapered rubber stopper, and ergonomically-angled acrylic pour spout also makes for effortless, aerated pouring free of any drippage. To use, just pop it into your bottle and pour away, and when finished, take the pieces apart and rinse to clean. Even more, this aerator pourer comes with a lifetime guarantee."
