It is a well acknowledged fact that wine tastes better after proper aeration. Aeration releases the delicate aromas of wine as well as improving the flavor of the wine. Fine Wine Toys
While I may not believe that statement, there is an industry out there producing gadgets for those who do, and some of it is pretty weird stuff.
There is the deSign Wine Aerator which comes in both bottle and wine glass sizes. All you do is insert the aerator into the wine and squeeze the bulb at the top to bubble your wines with air. And voilà, you have a nice head of foam, well for a few seconds anyway. I’m tempted to buy one just to show that this is very, very unlikely to do anything to wine, apart from adding a few bubbles.
If the deSign Wine Aerator sounds fishy, its got nothing on the Sea-riffic Pewter Aerators. At $30 each the puffer fish, sea horse, and octopus are used by inserting one of them into the mouth of a decanter and then pouring the wine over the aerator. I imagine you also get a good deal of foam with this method as well.
And if you really want to pump-it-up then there is the Air au Vin Wine Breather. Its been recommended by the BBC's Food and Drink programme, so it must work!
What ever happened to giving your decanter a good swirl a few times, if you are into that type of thing!
