The four best-selling beers ("Super Dry", "Ichiban Shibori", "Premium Malt's", and "Black Label") of commercial beer makers announced by the Taste and Fragrance Strategy Research Institute belong to the company According to the results of a survey on "beer scent" conducted on 10 sensory inspectors and 120 general men and women who drink beer on a daily basis, it was found that the scent of beer has a relaxing effect on people. is.
We are also investigating "differences in fragrance height (strength and weakness of fragrance) of each brand" and "general fragrance preference", and we have obtained interesting results. Let's look at them in order!
● First, what is the inspection method for "beer aroma"?
Four types of top-selling beer from beer makers (Super Dry, Ichiban Shibori, Premium Malts, Black Label) are prepared in a hard plastic cup in a blind format, and before and after including the "fragrance level" felt by the sense of smell in the mouth (later). , After judging without swallowing, spit it out into another cup) All 6 items ("Gorgeous scent before mouth", "Fruity scent before mouth", "Good scent before mouth" , "Gorgeous scent after mouth", "Fruity scent after mouth", "Aroma after mouth"). It seems that each item was ranked from 1st to 4th.
● "Professional of fragrance judgment", more than half of them evaluate "Pre-Mol"
In the inspection for sensory inspectors, among the above 6 items, "Ichiban Shibori" was ranked first in "Aroma after being put in the mouth", and "Premium Malt's" was ranked in 5 items such as "Gorgeous fragrance". It seems to have gained the most support.
Sensory test on "beer scent" / Test result of sensory inspector (difference in fragrance height)
Regarding the overall evaluation of fragrance (flavor preference), "Premium Malt's" had the highest number of votes with 6 votes, "Black label" had 2 votes, and "Super Dry" and "Ichiban Shibori" had 1 vote.
● General monitors are also sensitive to differences in scent
In the inspection on a general monitor, the "black label" ranked first for the two items of "good scent before scenting in the mouth" and "fragrant scent after scenting in the mouth" for the strength of the scent, and the others. For the four items, "Premium Malt's" is ranked first.
Sensory test on "beer scent" / test result of general monitor (difference in scent height)
As for the overall evaluation of fragrance, "Premium Malt's" was the most popular, as was the result of the sensory inspector, and 44 votes were obtained. The second place was "Ichiban Shibori" with 34 votes, "Black Label" with 25 votes, and "Super Dry" with 17 votes. Compared with the results of sensory inspectors, although there are some differences, "Premium Malt's" is generally highly evaluated.
● "Relaxing effect" on the scent of beer
Along with the sensory test, electroencephalogram measurement is also performed to investigate the effect on the brain that controls the sensation of fragrance. For 8 general men and women in their 20s and 40s, 4 types of beer, which is the same as the sensory test, and 5 types of distilled water added as odorless subjects were installed in front of the nose and the brain waves when smelling were measured. It seems that it was done.
In the test, alpha waves are used as a physiological index of relaxation, and the results show a characteristic tendency depending on the brand. According to this, the values of "Super Dry" and "Premium Malt's" were high, and especially for O2 (right occipital region) where α waves appeared most abundantly, "Premium Malt's" showed the highest value.

Comparison of EEG measurement test results / α power value (n = 6)
In response to this result, Professor Yoshihiko Koga, a brain science specialist who focused on "fragrance," said, "This alpha wave shows that brain activity is moderately suppressed and works smoothly in terms of neurophysiology. In other words, it means that the brain is calmly active. When a large amount of alpha waves appear and the brain is calmly active, a psychologically calm or relaxed state can be obtained. " Commentary.
"The α waves in the above two bands are considered to be an objective index of how relaxed the neurophysiological state is, and it is not that" Premium Malt's "showed a high α wave power value in the back of the head. , This scent physiologically suggests that it has a high relaxation effect compared to the other four types of samples. "
Premium Malt's is scary! It might be a good idea to drink more scented drinks tonight!
