It is simple. Place a glass under the Vinturi Tower Set and pour wine through the opening. When wine is poured into the Vinturi, its internal patented design creates an increase in the wines velocity while simultaneously decreasing its pressure. This difference in pressure draws in the proper amount of air, which mixes with the wine for the right amount of time, and delivers a better bouquet, enhanced flavors, and a smoother finish – the absolute perfect aeration. Its that easy.
