Why is the water sweet after drinking coffee? Does this have anything to do with coffee water and the sense of smell before and after the nose?

Whenever a guest comes to the store to sit down and want to taste a cup of coffee, Qianjie will pick up a cup of boiled water for the guest to have a cup of water and wait for the coffee to come out. Interestingly, some guests responded to the front street after drinking coffee: "Why is your water all sweet?"

In fact, Qianjie provides guests with only ordinary water, so why is it sweet to drink water after drinking coffee? Let's briefly share the secret with you in Qianjie today.

The taste of coffee stays in the mouth longer than other drinks. Take the traditional espresso as an example, when we taste the concentrated coffee, the first feeling is a strong bitter taste, and then we will feel the compound aromas such as nuts, caramel, chocolate and so on; as we swallow the coffee, the coffee left in the mouth will make our mouth feel slightly sweet. If you do not drink water to "gargle", the process of slightly sweetening the mouth can even last as long as 15 minutes.

This is because the small molecules that provide sour flavors such as flowers and fruits have dissolved with the aid of saliva and dissipated with swallowing movements, but other substances such as lipids, natural fats and oils, which we often call "oils", will remain more on the taste buds, giving us a slightly rough, astringent taste. But a good cup of coffee this astringent feeling will not give people too many negative feelings, more pleasant feeling.

We generally call it "Huigan", which is a kind of description of the aftertaste of coffee. In fact, it is not the kind of sweetness produced by eating sugar, but a feeling set off after the bitterness and astringency dissipate. So when we immediately rinse our mouths after drinking coffee, the bitter grease left in the mouth is washed away, reducing the burden on the taste buds and causing a sense of sweetness.

In addition to the "Huigan" reason, black coffee, such as hand-brewed coffee or espresso, is a high concentration of liquid for water. When we drink coffee, the taste buds are "bombarded" with sour (/ bitter) taste, and the sensitivity to sweetness increases in a short period of time, just like drinking water after eating lemon or traditional Chinese medicine.

Generally speaking, whether it is "Huigan" or the change in the sensitivity of taste buds to sweetness, it is one of the comprehensive manifestations of the sweetness of coffee. next time, after you have tasted this cup of coffee, you might as well take a sip of water to see if it will be like what Qianjie said. Drinking water is sweet.
