There are a few different styles of aerators but all are used in basically the same manner. You basically want to slowly pour the bottle of wine through the aerator which can either be handheld, in the bottle, in a stand or even in a decanter or glass. The key to the process is to make sure you pour at a somewhat slow rate. By pouring the wine too fast you may experience leakage in certain aerates, such as the Vinturi, or the wine may splash off the aerator which can be a bit messy and wasteful. Plus, the slower you pour the more air is getting to the wine before it even flows into the aerator. So take your time and enjoy the aerating process!
