“Oenodynamic”: Hydrodynamic of wine swirling
April 16th, 2018 | Tasting
When it comes to serious wine tasting one of the very first steps in the process is the so called ‘swirling’, necessary to release the bouquet of the wine. The theory behind it is that a gentle circular movement of the glass generates a wave propagating along the glass walls, enhancing oxygenation and mixing. In simple terms this action spreads the surface area of wine exposed in order to make the aromas more prominent.
Scientifically speaking this motion is not yet fully understood – it is all to do with fluid dynamics and the wave shapes generated by this simple movement. Suffice to say that it can make a real difference to the olfactory sensation that you will experience.
By the way, please don’t do what I have seen a few would-be ‘wine connoisseurs’ doing at the table – holding their glass stationery and moving their nose back and forth across the glass. Apart from making yourself giddy, this 70’s disco head movement will have no effect on the bouquet of your wine!
