Lucas MENOU: How many bubbles in your glass of bubbly?

The issue about how many carbon dioxide bubbles are likely to nucleate in a glass of champagne is of
concerns for sommeliers, wine journalists, experienced tasters and (really ?) open minded physicists
wondering about phenomena in carbonated beverages. I propose here a brief review of several articles
trying to enlighten the fine interplay between dissolved CO2, tiny gas pockets trapped within a filled
glass acting as bubble nucleating sites and ascending bubble dynamics during the gas discharging
process until bubble production is stopped through lack carbon dioxide. Basing us on both theoretical
model and experimental evidence, we will try to determine the whole number of bubbles likely to form
in a typical glass of champagne.
