Champagne, unlike other wines, undergoes a second fermentation in the bottle to trap carbon dioxide gas, which dissolves into the wine and forms the fabled bubbles in the bubbly. More than 600 different chemical compounds join carbon dioxide in champagne, each lending its own unique quality to the aroma and flavor of champagne.
But even with all of that flavor, champagne would be just another white wine without those tiny bubbles. As the bubbles ascend the length of a glass in tiny trains, they drag along molecules of those 600 flavor and aroma substances. They literally explode out of the surface as the bubbles burst, tickling the nose and stimulating the senses.
Some historian say that a French Benedictine monk named Dom Pierre Pérignon discovered champagne in the mid-1600s, and became namesake for the famous champagne cuvée, Dom Pérignon. The video notes that early champagne makers had a tough time with that second fermentation. Some bottles wound up with no bubbles at all while others got too much carbon dioxide and exploded under the enormous pressure, wasting the precious vintage.
So what’s the best way to pour a glass of bubbly and maximize the sensory experience?
For an answer, this video by BiteSizeScience references a study published in the Journal of Agricultural and Food Chemistry. It turns out that pouring champagne on an angle retains up to twice as much carbon dioxide in the champagne when compared to pouring down the middle of the glass. Those additional bubbles carry out more of the hundreds of flavor compounds in champagne.
