Bought this not being a wine connoisseur but always having wondered quite what difference oxidisation makes... well, look no further. This not only makes an amazing different to the taste of wine but a) provide entertainment when pouring the wine (you wait for the sound) and b) is a great blindfold game, guess the aerated wine! It really gets you thinking about the taste of wine and what tastes you prefer and why. Can be a little bit messy as there are one or two drips always, but overall great product.
