I did not tell you much, recently, about the professors of the Hautes Etudes du Gout, sorry.
This week : Gérard Liger-Belair
Gérard Liger-Belair is Professor of the University Reims Champagne-Ardenne (URCA)
He created there the team Effervescence, Champagne and Applications (GSMA – UMR CNRS 7331), which studies the processes linked with the dynamic of bubbles in liquids with dissolved gases (from the bubbles of champagne to the foams of the industry).
For the last decades, he developed an expertise on foams and bubbles, objects which attracted physicists, chemists and mathematicians.
The processes associated with bubble formation in champagne were poorly known until recently. However, in a glass of champagne, all the steps from birth to death of bubbles can be studied. Generally bubble are created on immersed particles, on the glass, and it evolves until detaching, reaching the surface.
These tiny spheres of carbonic dioxyde generate a wealth of phenomena of unpredicted complexity, and which are responsible for the whole sensation of the drinker. For about 15 years, Gérard Liger-Belair and his colleagues are developing analytical tools for studying bubbles.
Géard Liger-Belair published about 100 scientific articles, and about 10 books, among which :
- Effervescence ! la science du champagne, Odile Jacob, 2009
- Voyage au cœur d’une bulle de champagne, Odile Jacob, 2011
- Champagne, la vie secrète des bulles,Cherche-Midi,2014
He got scientific prizes for his research and publications.
