Will overswhirling your wine make it go flat?
Swirling has become so reflexive for me, I sometimes catch myself swirling my water glass. When it comes to bubbly,
your instinct that excessive swirling might make the wine go flat is correct. A little swirl won’t hurt, but it’s less necessary than with still wine—all that carbonation in a glass of sparkling wine releases the aromatics without you having to use any wrist action.
