The Pretty Eldest Daughter of a Scholar's Family

Chapter 406 The Wine Is Sour

It took about half an hour to walk from Dongming Fang to the West Gate, and after leaving the West Gate, it took about a quarter of an hour to arrive at Zhuangzi where the winery was located.

Zhang Ping'an spent this day in restlessness. Knowing that the Su family moved today, he still ran outside Zhuangzi several times to look at the capital, hoping that Su Yunduo would come to Zhuangzi.

He felt that as long as Su Yunduo came, he would be able to solve the problem of sour wine.

That's right, when Zhang Ping'an was inspecting the cellar on a routine basis today, he smelled an unusual sour smell in the aroma of the wine as soon as he entered the cellar.

According to the method taught by Su Yunduo, he led people to investigate one by one, and finally found out that the sour smell came from several jars of pressed wine in clay pots stored at the exit of the wine kiln.

Although the source was found out, Zhang Pingan still didn't dare to be careless. After all, most of the wine was in sealed containers, and he wasn't sure if other wines were sour.

After thinking twice, Zhang Pingan sent an urgent letter to Lu Jinkang even though he knew that Su Yunduo would not be free today.

Seeing that it was getting late, but no one came from the city, Zhang Ping'an was restless, hating himself for not being able to solve his master's problems, and had to wait for Su Yunduo to rush over from the city to solve the problem.

Until he saw two carriages and a few fast horses coming from the city in the distance, Zhang Ping'an's restless heart fell instantly.

It was not only Su Yunduo who got off the carriage, but also a face-to-face noble lady, which made Zhang Ping'an's heart ache again, and he had some doubts about Su Yunduo's purpose here.

Could it be that Su Yunduo didn't receive the letter he sent into the city, and was just here to accompany the nobleman on vacation?

But it shouldn't be, even if you come with someone on vacation, it shouldn't be today.

Before Zhang Ping'an could figure it out, Su Yunduo's clear voice sounded, which solved Zhang Ping's doubts: "Auntie, let Zisu take you to resettlement first, I have to go to the wine cellar to see the situation first."

It turned out that the lady was the master's aunt, and it turned out that the master already knew that there was a problem with the wine cellar.

For no reason, Zhang Ping'an felt that his eye sockets were slightly hot, and when Su Yunduo looked over, he hurried to greet him.

"Can I visit your cellar?" Su Jieting made a request to Su Yunduo.

Su Yunduo paused slightly, Zhuan Er smiled and said: "Why not? If Auntie doesn't feel tired, please go and have a look with me."

As she spoke, she signaled Zisu to take Su Jieting's mother-in-law and maids to carry Su Jieting's cage to resettle, while she herself supported Su Jieting and went straight to the wine cellar.

This time Su Yunduo only brought Zisu a maid, but Su Jieting had several maids and wives beside her. Apart from the maid who followed Zisu to settle down, there were two other maids with Su Jieting.

Since Su Yunduo came here to deal with matters, he couldn't just serve Su Jieting.

Su Jieting also wanted to take the opportunity to investigate this niece, so after walking for a while with Su Yunduo's support, she patted Su Yunduo's hand and said, "You go and get busy, let's go slowly."

Su Yunduo was anxious in his heart. Although Lu Jinkang was watching over there in the palace, he still had to find out the reason earlier to ensure the quality of the wine and eliminate the hidden dangers of the winery.

Since Su Jieting asked her to take care of things first, Su Yunduo no longer insisted on supporting Su Jieting to walk slowly, but gave up the position to Su Jieting's maid, and she asked Zhang Ping'an for details as she walked.

Knowing that Zhang Pingan had picked out all the wines with special sour taste by sniffing, Su Yunduo couldn't help but praised: "You did a good job! I'll tell you the specific reason after I read it."

Seeing Zhang Ping'an's eagerness to ask for answers, Su Yunduo couldn't help saying more: "Wine is sour due to the following reasons.
One is that the sugar content of the selected grapes is too low, and the fermentation is not sufficient during the winemaking process, so the wine is naturally sour.This should be ruled out.

The second is that the fermentation time is too long, and it will become sour after fermentation.This can also be ruled out.

The third is that after the grapes are washed, the water on the skin of the grapes is not dried before entering the winemaking process, which will also cause the wine to become sour.When we brew wine, we strictly control this step, so this one can also be ruled out.

Fourth, after the wine is brewed, the dregs are not filtered in time, and the dregs continue to ferment into vinegar, which naturally becomes sour.This one is possible. You just said that those sour wines are placed near the exit of the cellar. If I guessed correctly, it should be the last filtered wine.

The fifth is that accidental pollution occurred in the process of taking and the sealing is not tight enough to cause the wine to become sour.This is the most likely one. "

After Su Yunduo finished speaking, he analyzed in detail the various reasons that might cause the wine to sour, and finally looked at Zhang Pingan who looked thoughtful and asked: "I wonder if Ping An was in Geshan Village or his hometown, and whether there was Have you ever seen a villager brew their own liqueur?"

Zhang Pingan scratched his head in embarrassment: "I... the slave has never seen it before."

Su Yunduo shook his head slightly. It is reasonable for Zhang Pingan not to have seen Zhang Pingan's situation, so he added something special: "Whether you use grain or fruit to make wine, improper use will cause pollution. The liquid is sour."

Zhang Pingan tried his best to digest Su Yunduo's words. He knew that it was Su Yunduo's special advice to him. When he was about to reach the wine cellar, Zhang Pingan finally digested most of Su Yunduo's words. Naturally, there was something he didn't understand in his heart. So he asked cautiously: "The so-called pollution caused by improper use, is there any other meaning besides the pollution caused by the dirt brought in by the dirty tools?"

Su Yunduo gave Zhang Pingan a thumbs up in his heart, and of course he also gave a big thumbs up for his good use of people, and the smile on his face naturally became brighter: "Yes, the so-called improper use is the first to be pointed out. The most natural thing is that the tools used are not clean, such as stains, such as water. In addition, the failure to perform a qualified seal after use is also an aspect.

There is a component in wine that is not very stable. It will form acidic substances when combined with air. When the acidic substance content reaches a certain level, the wine will naturally be sour. "

From the conversation with Su Yunduo, Zhang Ping'an had roughly sorted out the reason for the sourness of those jars of wine, and he was naturally ashamed and ashamed.

Not to mention whether the other wines were sour, but the jars of wine he found were indeed due to several reasons as Su Yunduo analyzed.

First of all, those jars of wine were filtered late, and the fermentation was slightly overdone.

When filtering, I felt that the wine smelled slightly stronger than the previously filtered wine, but after tasting it, I felt that the taste was good, so no one took it seriously.

The second is that during the process of using it, I pay great attention to the cleanliness of the tools used, but the sealing process after taking it is not proper, otherwise the smell will not come out, and it will not be so easy for him to take it with someone. Pick it out.
