As the saying goes, "good wine doesn't go to the head." What does it mean to reach the summit? Does it taste good？

As the saying goes, "good wine doesn't go to the top", and the top is not good wine. This often becomes the most intuitive way to identify whether a wine is good or not.

But besides trying to drink with your own body, can you directly see whether the wine is on your head through your eyes? See if there is "oil" on the surface of liquor. If there is oil, drink it carefully! Because this substance is the real murderer who caused the "top"-fusel oil.

It is often presented in the form of "oil", hence the name fusel oil. It is the general name of all kinds of alcohol substances, and it is an inevitable by-product in the brewing process. Fusel oil exists in any liquor, but the content is different.

When the content is low, it is an integral part of liquor flavor, which brings special flavor and is harmless to human body.

Sec-butanol brings fragrance; N-butanol, bringing jasmine fragrance; N-amyl alcohol, bringing creamy taste; Phenylethanol brings rose fragrance.

But when its content is high, it will cause poisoning and anesthesia damage to human body, make the nervous system congested and make people dizzy.

So people often feel that they woke up after drinking wine the day before, but their heads are very sour!

The reason is that fusel oil stays in the body longer than alcohol and is difficult to excrete. Although the wine is awake, the anesthetic effect of fusel oil has not dissipated?

In fact, most fusel oils are unrecognizable to the naked eye. Only when the alcohol content is low or the temperature is low in winter will it be found.

Fusel oil is soluble in alcohol and insoluble in water, and its density is smaller than that of water. When the alcohol content is low or the temperature is low, it will precipitate and float on the wine surface and be discovered by us.

When you see oil flowers floating on the water, it means that the fusel oil content is already high. I suggest you drink less of this wine?

What kind of fusel oil is high in content?

Experts believe that there are two kinds:

Corn wine (corn wine)

The most common cheap wine in various leisure hotels often leads to drinking too much. The reason lies in the raw material it uses-corn.

As mentioned earlier, fusel oil is an inevitable by-product in the brewing process, which is related to the content of protein in raw materials.

Some scientists have found that the fusel oil content in sorghum liquor is low, the fusel oil content in grain liquor is moderate, and the fusel oil content in corn liquor is seriously exceeding the standard.

From this, we can find a phenomenon: corn wine is mostly low-end loose wine in the market. This kind of corn wine (corn wine) has high yield, fast brewing and low cost. However, for the sake of profit and limited conditions, ordinary small workshops will not remove the endosperm of corn, nor will they specially filter to reduce the fusel oil content in the process of wine flow, so this fusel oil content is very high and it is easy to get drunk.

High-quality wines are mostly made of sorghum or whole grains, and regular manufacturers will deliberately reduce fusel oil, so as not to cause consumers to "drink" and affect brand reputation.

Inferior low-alcohol liquor (tail liquor, etc.) )

There is also a kind of wine, although it is sorghum wine, but it is mostly "fusel oil"-a finished wine made from the wine behind the winery.

Brewers often have a famous saying "pinch the head to the tail", which means that the wine that flows out first and the wine that flows out last are of poor quality, so give up!

The wine in the later period of the winery mentioned above refers to the last wine flowing out.

This wine has low alcohol content and high fusel oil content, and is generally abandoned by wineries. However, driven by the interests of some businessmen, these inferior wines entered the market.
