I bought this item after visiting a wine bar in Redlands, Ca. The proprietor demonstrated the reason he used the Aerator with each pour. The wines sampled with the Aerator were superior each time. At home I use it when I decant a bottle or pour a glass directly from the bottle. Try it I think you will notice the difference. I have used this item as a gift on more than one occasion and received many thanks from the recipients.
Just like the other review says, pour two glasses, one using this aerator, one without and see the difference for yourself.
Best Way to get to know the Vinturi Wine Aerator is pour a small amount of your favorite red wine into a glass and take a sip... then after you finish, pour a full glass using the Wine Aerator and notice the differences... Nothing subtle about it! Best thing is that it makes a $10 bottle of wine taste like a $15-$20 bottle.
