What if I can't get the flavor of the coffee? What is the sense of smell behind the nose? Is the flavor of hand-brewed coffee smelled?

"Why can't I get the flavor of coffee?" This is the most common question I have ever heard about flavor in front of the street. Of course, Qianjie also shared a lot of ways to taste the coffee.

But this article is to explore whether the flavor of coffee is drunk or smelled. According to the usual expression, the flavor of coffee is drunk. From a scientific point of view, coffee contains more than 850 aromatic substances, and most of them are volatile, that is to say, the taste buds on the tip of our tongue can not feel the flavor of these substances. Only a small number of aromatic substances are water-soluble, such as citrus acid, which we often drink, such as malic acid, citric acid, lactic acid and so on. (so the most distinguishing flavor of coffee is citrus.)

There are also some substances that are both water-soluble and volatile, such as acetic acid and caramel, which can be tasted by the tongue or smelled by the nose. If you drink it and feel it with your tongue, you can only feel the bitterness of the coffee.

The nose can sense more aromatic substances in coffee (it depends on the individual), such as flower, fruit, caramel, chocolate, cream, wood, scorch, medicine, etc., can be smelled through the nose. This is why many friends are attracted by the aroma of coffee. But this is not the whole function of the nose to perceive the flavor of coffee. In general, we put the nose close to the nose to smell coffee, which is called "pre-nasal smell". It can intuitively feel the dry fragrance of coffee beans after grinding and the wet fragrance of coffee after brewing. And the other is the sense of smell behind the nose!

The nasal cavity is connected to the oral cavity. When we drink the coffee, the substance in the coffee liquid is vaporized and volatilized through the catalysis of saliva, and then goes back into the nasal cavity along the nasopharyngeal tube, so that we can feel more flavor. For example, after the entrance feel the fragrance of flowers, berries, caramel, chocolate. This is also the flavor that we often mistakenly think of as drinking the tongue. In fact, it also comes from the nose. For some friends, they can only drink the sweet and sour taste of coffee, but not the flavor of coffee. It is possible to sense the taste of coffee directly with only the tongue. So if you want to "drink" the flavor of coffee, you might as well try Qianjie.

Before drinking coffee, you might as well smell the wet fragrance of coffee, then take a sip, use your tongue to feel the taste and taste of coffee, close your mouth and exhale gas from your nose, you will exhale the aroma of coffee through the nasal cavity, thus perceiving the flavor of coffee through the sense of smell behind your nose.
