We now know why champagne bubbles rise straight up

The wake of rising bubbles in carbonated drinks can disrupt other bubbles. When the molecules that give fizzy beverages their flavor coat the bubbly, they can form columns of stability as they float.

Champagne may contain surfactants that allow bubbles to rise in a column.

The chemicals that give champagne and other carbonated beverages their taste can cause the bubbles to rise in columns.

As bubbles rise, they create a wake that can knock other bubbles around. Bubbles in champagne rise in vertical columns from the bottom without being pushed.

Roberto Zenit from Brown University, Rhode Island, and his colleagues removed gas from fizzy beverages, including carbonated drinks such as beer or champagne. The researchers then poured liquids into a tank that had a needle in the bottom. They pumped air through the hand and measured the rise of the bubbles.

Researchers combined their observations with a mathematical formula that explains how the properties of liquids affect the amount of swirling near bubbles. Researchers found that two factors are responsible for mixing: The size of bubbles and the concentration of molecules known as surfactants. The fatty acids in champagne give it its fruity notes, and the proteins in beer contribute to its flavor. These molecules, by sticking to bubbles, can alter the surface movement of the bubbles.

Bubbles that are large and elliptical, or bubbles coated in surfactants, encourage swirling. This interrupts the trail
