How long will it take you to count bubbles in your beer glass? Without sleeping for over a week and going fast again. Fortunately, CNRS scientists worked for us and established the calculation method … more or less reliable.
Science sometimes has the art of answering questions that no one asks: whyThe Comment The How many cocks does it take The How many children are there? The Here is further evidence of the usefulness of our researchers: We now know that a glass of beer contains between 200,000 and 2 million bubbles, but also that beer contains more bubbles than champagne.
How to put beer in your glass properly
This question was the subject of a very serious study by two researchers from the University of RheimsPublished in CNRS and in Journal . Because the occurrence of bubbles is actually much more complex than it sounds. The formation of bubbles depends not only on the nature of , But also temperature, size of glass, volume of liquid or Environment. ” 100 ml of champagne is poured directly in the middle of a vertically oriented flute that will contain approximately one million bubbles. But the Served more slowly by putting on the side of a bent flute (a technique that better conserves CO)2 Dissolve) will give tens of thousands more bubbles », Indicating the study’s lead author, Gayard Lager-Belair.
or, “ Presence of CO2 Breach is a required sensory parameter, Because bubbles transport compounds And fragrant, The scientist emphasizes Gerard Liger-Bellair. We previously showed that a minimum concentration of 1.2 g per liter of CO2 Requires dissolving in sparkling wine In mouth »
How long will it take for my beer to lose all its bubbles?
It remains to be known how to count. Gérard Legger-Bellair and his colleagues first measured the amount of CO2 Pouring beer into a tilted glass dissolves in a lager (heineken) to preserve CO2 Dissolved), and to a tasting temperature of 7.22 ° C. He modeled then Spontaneously collects to create streams of bubbles in the crevices of the glass. Finally, using a very large camera ()High speed photography), He observed how the bubbles grow and carry the dissolved gases to the surface, until no dissolved gases remain in the beer. Results: Between 200,000 and 2 million bubbles, half a pint of lager (25 Cl) is released before its gas is completely “emptied”. Not a very accurate estimate, it is true, but always more reliable than counting bubbles one by one.
Note that this estimate is not valid for champagne. Surprisingly, glass imperfections affect the two drinks differently, with more bubbles forming in the beer when the cracks in the glass are larger, researchers note – maybe beer is often served in mugs is. And if you think that to calculate the number of bubbles, hereUse :
