Instructions
Let's  raise  a  toast  to  .  And  its    bubbles.  Because  new    says  the  bubbles  aren't  just  tickling  your  tongue.  They're  erupting  with  aromas  vital  to  the  taste  of  the  beverage.  A  team  of  (who  else)  French  researchers  used  mass  spectrometry  to  nose  around  a  glass  of  champagne.  They  found  that  concentrations  of  certain    compounds  were  higher  at  the  surface  of  the  glass  than  in  the  liquid  itself.  They  report  the  finding  in  the  Proceedings  of  the  National  Academy  of  Sciences.  The    say  the  sea  shares  champagne's  secret.  If  you've  ever  enjoyed  ocean  air,  it's  because  compounds  called    are  dragged  along  with  bubbles  in  the  waves.  When  those  bubbles  burst,  the  surfactants  break  into  smaller  molecules  called  aerosols  that  are  suspended  in  the  breeze,  giving  coastal  areas  their  distinctive  oceany  odor.  In  essence,  a  glass  of  champagne  hosts  a  small  version  of  this  process,  but  the  bubbles  bring  more  appetizing  aerosols  to  the  surface.  Legend  has  it  that  Dom  Perignon  shouted  "I'm  tasting  the  stars"  when  he  uncorked  his  first  bottle  of  champagne.  But  it  was  physics  and  chemistry,  not  astronomy,  that  he  was  really  savoring.
