Pouring the wine from the top of Aerator. As you pour wine into the aeration chamber, it speeds up as it circulates and drains through the air channel at the bottom. The resulting pressure differential "sucks" the surrounding higher-pressure air into the wine, thoroughly mixing the two for a few seconds before the liquid hits your glass. The other main thing that sets this Aerator apart is its built-in filter that sits at the top of the aeration chamber. This mesh filter will catch any sediments and lees in your wine.
This product does not include red wine and wine glasses.
