Yes, aerating wines helps open up young wines and can make younger wines more balanced and smoother. Red wines improve greatly with aeration but even younger white wines achieve benefits from aeration.
The key to aeration is timing! Some younger wines can take up to 2 hours to open up while an hour is great for a mature red. However, older wines (15 years or more) should not be aerated for more than minutes.
How to aerate your wine?Many people use a decanter and an aerating funnel. The increased surface area of the decanter allows faster aeration. The use of an aerating funnel induces air into the wine during the pouring process.
There are a number of good quality wine aerators and pourers (Vinturi, Decantus, Vino Dose, etc.) on the market which do a very good job and eliminate excessive waiting time.
There is also a battery powered wine breather system which has a steel rod that is inserted into the wine bottle optimizing the flavor of the wine with bubble aeration.
Of course there is the old tried and true method of swirling the wine in your glass.
