How Do All Those Bubbles Get Inside Champagne?

More

Science Friday shares how to celebrate this coming weekend. This New Year’s Eve, raise a glass—but instead of drinking your champagne, try watching it instead. You’ll see delicate trails of bubbles floating upward through the wine. We tracked down bubbleologists Dick Zare and Charles Bamforth to explain what these bubbles are made of, how they form, and how the fizz in champagne stacks up against beer foam. (Spoiler alert: Bamforth says he’ll be ringing in the New Year with an IPA.)

Bubbles form in your drink due to imperfections in the drinking container. In this video, the glass on the left has been coated and its surface passivated, or made smooth, which suppresses bubbling.
