| Abstract
| - For the very first time, a classical flow visualization technique was used to capture the fluid motionin traditional flutes and coupes poured with champagne. It was found that glasses engraved aroundtheir axis of symmetry produce a rising gas column along the vertical glass axis that induces, in turn,steady state recirculating flow regions. In the case of the classical engraved champagne flute, thewhole domain of the liquid phase is homogeneously mixed, whereas in the case of the engravedchampagne coupe, the recirculating flow region does not occupy the whole volume in the glass. Inthe engraved coupe, a dead-zone of very low motion was identified, which inhibits the formation ofthe collar at the glass edge. Our results finally strongly suggest that the glass-shape and engravementconditions should likely have a strong impact on champagne tasting by modifying the kinetics ofrelease of carbon dioxide molecules and aromatic volatile organic compounds from the liquid medium.
