Optical Techniques Gauge Champagne Bubble Stability

Nadya Anscombe

The hallmark of a good glass of champagne is a stable ring of bubbles — called a collar — at the top of the glass. The formation and disappearance of these bubbles are delicate phenomena that are sought after by champagne makers, but they are not easily reproduced. They are determined by the adsorption layers formed at the gas/liquid interface on the inside of the bubbles and at the air surface of the liquid. Researchers in France have used optical techniques to investigate the stability of bubbles in champagne. The adsorption layer is essential for the stabilization of bubbles and...Read full article
