Acoustics researchers suggest that it's possible to hear the quality of champagne just by listening to the bubbles form. According to the University of Texas scientists, "There is a well-known notion that the quality of a sparkling wine is correlated to the size of its bubbles, and we are investigating whether the bubble size distribution of a sparkling wine can be obtained from simple acoustical measurements." Many people believe that smaller bubbles mean a better taste. From Smithsonian:
To measure the sounds of wine, researchers used small hydrophones—microphones which can record underwater sounds. They poured California Brut and Moët & Chandon Imperial champagne into flutes and listened in as the bubbles formed. The results suggest that they could indeed hear the fine champagne, discerning that bubbles of this drink are slightly smaller in size, more evenly sized and have more activity than the lower-quality sparkling wine.
