An aerator’s purpose is to expand the surface area of wine, which allows the air to mingle with it. Aerators force air to be circulated throughout it, the end result is a wine with an expanded aromatic profile and/or softer tannins.
A handy aerator will easily do the trick in minutes. A Vinturi Wine Aerator for example, is held above your glass while you pour wine through the top of the aerator. As the wine flows through the aerator, it breathes¬Ě as bubbles are sent through it. An aerator is appropriate for casual meals, where time is of the essence.
