The study authors explained that the bubbles in the beer hold flavor compounds and when a bubble bursts, the flavor is released into the air — right into the drinker’s nose.
The foam acts as an efficient gas exchange surface funneling aromas toward the drinker’s olfactory sensors, and it provides a drinker’s first tantalizing entrée as to the quality of the beer’s flavor, freshness, refreshingness, and wholesomeness,” read the study’s introduction. “The foam prevents beer from losing its flavor due to changes in its composition caused by exposure to air,” the study authors said.
They measured the aroma in the beer before it was frothed and after by using ultrasonic waves that mimic the way beer behaves when it’s poured into a glass. This allowed them to measure the scent of a flat beer and a frothed beer.The researchers found that the aroma components were 1.3 to 1.9 times higher in the beer with a frothier head compared to the flat beer.
