Roberto Zenit, a senior author on the study, explains, “These protein molecules that impart flavor and uniqueness to the Champagne are also responsible for the stability of the bubbles they produce.”Īpart from surfactants, the bubble size too determines its stability. Surfactants reduce tension between the liquid and gas bubbles, facilitating a seamless and straight rise to the top. ![]() Researchers were intrigued: What caused Champagne’s bubbles to ascend in such an orderly fashion? Surfactants: The Science of Champagne Bubblesĭelving deeper, the study unveiled that the straight rise of bubbles in Champagne and sparkling wine is due to the presence of soap-like compounds called surfactants. ![]() This phenomenon, called a stable bubble chain, contrasts with beverages like beer, where bubbles often take a more chaotic route upwards. They feature a continuous rise of gas bubbles, rushing to the surface in a single-file line. But Champagne and sparkling wine stand out. In the world of carbonated drinks, from soda to beer, the bubbles’ behavior varies. ![]() Champagne toasts at celebrations are iconic, but have you ever wondered about the perfect straight-line rise of its bubbles? Scientists at Brown University and the University of Toulouse have uncorked the answer, revealing the science behind the behavior of bubbles in our favorite carbonated drinks.
