Did you know that it is dirt and not carbon dioxide that make champagne and sparkling wine fizz? In a perfectly smooth and clean glass molecules of carbon dioxide would evaporate invisibly which is why for ages people thought that it was imperfections in the glass itself that caused the fizz.

Technology advancements in photography have shown however that these small imperfections in glass are in fact too small and that carbon dioxide can not adhere to them. Instead it is the small pieces of dirt, fluff and dust which act as condensation nuclei for the dissolved carbon dioxide making the bubbles.
