Champagne distinctive "mushroom" shape becomes more apparent. The aging of the Champagne post-disgorgement can to some degree be told by the cork, as, the longer it has been in the bottle, the less it returns to its original cylinder shape. Champagne is usually served in a Champagne flute, whose characteristics include a long stem with a tall, narrow bowl, thin sides and an etched bottom. The intended purpose of the shape of the flute is to reduce surface area, therefore preserving carbonation, as well as maximizing nucleation (the visible bubbles and lines of bubbles). Legend it has it that the Victorian
Champagne called "" (the term is also used for simply breaking the head of the bottle). 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
