I find holding this over the glass an odd process. I would never make my guest do this, and it drips all over the place. Aerator does positively improved the taste of red wine, but there must be a more Mom friendly way.
I have many aerators and have found this one to be absolutely fabulous. In fact, I have purchased 3 of them for myself and 1 for my friend. They are great for not only the aerating purpose, but it also has the cap to keep the wine fresh.
