It seems that if you want to swirl your wine in the glass before sniffing it, there is an optimal combination of depth, glass diameter and rotation rate.
Depending on these factors, you can generate dynamic wave patterns with either single or multiple crests so that the amount of mixing between air and wine can be controlled.
Today’s invention is therefore a wineglass turntable for viniculturists.
Pour the wine in to the marked level and then run the turntable at the correct speed. After the appropriate interval, smell the wine.
Oh, and if it smells ok, drink it.
