Pouring sparkling wine while tilting the glass at an angle and gently sliding in the liquid along the side will preserve the most bubbles, as opposed to pouring directly down to create a head of "mousse", according to a study, "On the Losses of Dissolved CO during Champagne serving", by scientists from the University of Reims. Colder bottle temperatures also result in reduced loss of gas. Additionally, the industry is developing Champagne glasses designed specifically to reduce the amount of gas lost. Champagne has been
