A crucial step in wine tasting is the so called swirling, necessary to release the bouquet of the wine: a gentle circular movement of the glass generates a wave propagating along the glass walls, enhancing oxygenation and mixing. Although being used in a large variety of other applications (e.g. cells cultures in orbital shaken bioreactors) this motion is not yet well understood. In this fluid dynamics video we show the large variety of waves shapes generated by this simple movement, and we identify a group of dimensionless parameters governing the flow.
