Great for times when you don't have a decanter handy, but need to aerate a bottle in a hurry! This nifty pourer/aerator combo utilises the Bernoulli (a Swiss scientist) effect where the reduced pressure of a stream of fluid (wine) draws an air flow through diagonal thin tubes inside the unit.

It also features a removable top lid which is good for covering the bottle in restaurants, wineries or when outdoor entertaining.
