Is it normal for the cup to smell after drinking white wine for a while? What is the reason?

I did encounter something that stinks after drinking white wine, which left a deep memory for me. Here's the story.

This story happened about five years ago. At that time, I was still working in a private enterprise. After a hard year, it's the 24th day of the twelfth lunar month. After the Lunar New Year, the company began to have a holiday, and I began to enjoy the holiday very comfortably.

I ate and slept at home, and after a few lazy days, I began to lose sleep at night, but I couldn't sleep anyway. In fact, I know in my heart that I slept too much during the day.

Because I couldn't sleep, I got up to find something to do. Because the Spring Festival is coming soon, my parents do a lot of cleaning work at home, such as washing curtains, cleaning the stove at home, cleaning sheets and bedding at home and so on.

I have hardly helped them these days. I couldn't sleep that night, so I went to make trouble. I took the initiative to help my family do a general cleaning. My main goal is to clean the wine cabinets and cabinets in the living room.

In those years, my father would occasionally have a small glass of wine, which was specially prepared by my mother. A beautiful little glass, simple and generous, is also my father's favorite thing. It's not big, but it's really expensive, so dad also cherishes it.

On weekdays, I also noticed that after my father finished drinking, my mother didn't seem to have the habit of wiping cups, but put them directly in the wine cabinet with the rest of the white wine bottles;

Since it is a general cleaning, the first step is to put the things in the wine cabinet in order, clean the used wine glasses and teacups on weekdays, pick up my father's wine glasses, fiddle with them for a while, and inadvertently approach my nose, and I smell a stench;

The next day, I blamed my mother a little, but also reminded her that the wine glasses that my father had drunk should be cleaned frequently in the future, and they would stink in a few days.

When I got home, my mother and I talked about glass. Unfortunately, my cousin came to visit my parents at home. After hearing our conversation, he also popularized some knowledge about liquor for me. From that day on, I realized that the reason why the cup stinks after drinking white wine for a while is still very complicated, not as simple as I thought;

Today, I saw this question from the subject: after drinking white wine for a while, the cup smells stinky. Is it normal? What is the reason? Then let me tell you something about my own thoughts over the years:

1, there is a saying that after drinking wine, the cup stinks, indicating that the liquor you drink is Luzhou-flavor and fermented by pit mud, because the liquor contains ethyl acetate and has a little odor;

2. However, for the above statement, I feel that the explanation is not very detailed, because normal white wine is empty and fragrant. After drinking the wine, the cup has an unpleasant taste, which may be that there is something wrong with the white wine;

3. The bad smell of liquor is mostly caused by moldy brewing materials, unsanitary brewing equipment and high brewing temperature.

4. If the content of methanol exceeds the standard in liquid liquor dominated by edible alcohol or low-end bulk liquor, such problems will occur;

5. Many people who drink alcohol know that liquor contains odorous components, which are covered by aromatic substances or irritating substances in most cases, and the odor will not be too prominent. When we leave the liquor for a while, there will be a stinking wine glass.

6. If the wine glass stinks after drinking liquor for a period of time, this situation may be a manifestation of poor quality of liquor;

7. If it is grain wine, an empty cup is unlikely to stink in a high probability. If the glass is left for a long time and smells bad, some substances on the glass may be moldy and deteriorated;

At the end of the paper, I still want to say a few words. Is it normal for the cup to smell after drinking white wine for a while? What is the reason? What I encountered at home may be that the wine glass stinks for a long time, so some substances on the wine glass should be moldy and deteriorated;
