Chapter 64 Confucius and Mencius' Winemaking Theory

Originally, according to Confucius and Mencius's idea, he asked his mother to stay in the hospital for a few more days.

But the family is in a mess now, how could Mother Kong be in this mood?
So when Confucius and Mencius returned to the ward, she insisted on going home.

Knowing his mother's knot, Confucius and Mencius did not dissuade her.

Kong Ren parked at the door with a [-]% new Wuling bread. This car was bought by Kong's father when he planted purple grapes, and it is already a symbol of the Kong family.

Carefully helped his mother into the car. As soon as Kong Ren stepped on the accelerator, the family of three flew towards Kongjia Village like an arrow.

The straight-line distance from Kongjia Village to Weixian County is 23 kilometers. It is said that it was the residence of the saint when he traveled to Zhongzhou, but the authenticity remains to be investigated.

Its biggest feature is its remoteness, and the whole village has only one country road to communicate with the outside world.

Confucius and Mencius lived on the side of the country road, and the small brown three-story building looked particularly eye-catching.

Although it has been so long, Confucius and Mencius still remember the pride on his father's face when the building was completed.

This is the first duplex building over three floors in Kongjia Village!

But now Kong Meng frowned, because the LED light in front of his house was off.

This is so weird.

Because of the remote location, there are no street lights in Kongjia Village at night, and if everyone comes back late after working in the field, the road will be very inconvenient.

After the house was built, Confucius specially spent several hundred yuan to let Confucius and Mencius bring back a 100-watt LED incandescent lamp from Zhongzhou.

As soon as the light came out, half of the village was illuminated directly. At the same time, Father Kong promised that the light would not go out before midnight, which won unanimous praise from the villagers.

Is father not at home all the time?

Get out of the car, open the door, and see the darkness, the gloomy atmosphere gives people endless depression.

Snapped!
Reach out and press the light switch, and the yard instantly brightens.

Kong Meng was taken aback.

On the steps, a man in his 50s was smoking a cigarette, who else could he be?
Seeing his father for the first time, Kong Meng's nose couldn't help but feel sour. The other party's black hair turned out to be more than half white, and the strong and optimistic face disappeared. Now there is only decadence.

Seeing that it was the eldest son, Father Kong was obviously stunned, but soon he returned to his original appearance.

"dad……"

Just as Kong Meng was about to say something, his mother's angry voice rang out behind him, "I said, you old bastard, you don't go to the grape field to guard, what are you doing sitting here?"

Kong's mother fainted, but Kong Meng did not see his father in the hospital. It was not that the old man didn't care about his wife, but that the whole family was worried about the grape field.

When the purple grapes were first planted, because the fruit was rare, many villagers often went to his field to try a few bunches while the Kong family was away.

One or two strings looks like a small number, but it can't stand the crowd!

According to Kong's mother's estimate, this item alone caused a loss of at least 5000 yuan to the family.

Also from then on, Father Kong had a habit of riding a bicycle around the fields day and night when the purple grapes were ripe, even if the sky fell.

Taking another puff of cigarette, Father Kong smiled wryly: "Didn't you just come back... and now the difference between patrolling and not patrolling is basically not big. This year, every household has grown grapes, and the family can't finish it. How can it be possible to miss our family's things?" ?”

"Then you can't just sit here stupidly. Have you swept the yard? Can't you cook, and don't you check what time is it?" Mother Kong can always make sense at any time.

Father Kong sighed, got up and walked slowly towards the kitchen.

Seeing this, Confucius and Mencius asked his younger brother to help his mother back to the house to rest, while he himself followed to help.

Father Confucius was a chef when he was young, and his cooking skills were very good. He quickly cooked two dishes and one soup. The shredded meat was soft and the vegetables were green, which looked very attractive.

It's a pity that no matter how successful the cooking was, Father Kong didn't show any joy on his face.

After a short silence, he suddenly asked his son: "I heard from your brother that you can solve the wine production problem and the funding gap?"

Apparently, Kong Ren had already talked with his father on the phone.

Kong Meng hurriedly made an oath: "You don't have to worry about it, give me two days, and I guarantee that the money will be in place on time."

Father Kong was not as easy to fool as Kong Ren: "Let's talk about how you plan to solve technical problems first."

Kong Meng smiled faintly: "Dad, wine making technology may be difficult for those who don't know it, but as long as you know its fermentation principle, it is much simpler than growing grapes.

Just put the cleaned grapes into a sterilized fermenter, undergo aerobic and anaerobic fermentation, then distill, blend, and enhance aroma..."

Father Kong waved his hand and interrupted: "Okay, your father is not stupid, of course I know all this, don't think that if you study for a few more years, you will understand everything. If grape wine is really that easy, I still need to worry about it?"

Kong Meng's expression remained the same: "Dad, you know it but don't know why, such as the problem of methanol exceeding the standard.

In the process of grape fermentation to produce alcohol, the pectin in the cell wall will also be decomposed under the action of pectinase to generate a very small amount of methanol.

For personal use, these very small amounts of methanol will not cause harm to the human body, but if you want to carry out industrial production, you must distill and purify.

But in this way, the methanol in the wine will be enriched in the still, and if it is not treated in time, the real wine will turn into poisonous wine in a blink of an eye. "

But Father Kong didn't believe it: "Your father doesn't read much, so don't lie to me. The dog in our village also owns a winery. Why doesn't the wine he brews have such a problem of excessive alcohol?"

"Dad, the dog eggnog factory has been in operation for so many years, when did you see him buy half a catty of grapes?"

Kong Meng explained patiently: "The wines he produces are all blended with high-purity alcohol and essence, and of course they do not contain methanol."

"Is it mixed with alcohol?" Father Kong was a little confused, then he threw the spatula directly on the chopping board, got up and walked out the door.

Confucius and Mencius hurriedly asked, "Where did you go?"

Father Kong said angrily, "Damn it, alcohol mixed with crap can pass the test. Why can't I make real wine from grapes? I'm going to ask the grandson of the food supervision bureau to judge it!"

Kong Meng hurriedly stopped his father: "Dad, everyone knows how the wine sold by Goudan came from, so it has been half-dead these years. Our wine uses real grapes. As long as the excess methanol is removed, the business will definitely be ten times better than his. Times!"

Father Confucius was dubious: "Do you really have a way to remove the methanol?"

Confucius and Mencius said to themselves: "Of course, although the principle of making wine is simple, there are many details in the actual brewing.

For example, how to select fruit, how to clean the pulp, how to sterilize and inoculate, how to control the temperature during fermentation, when to add sugar, how much sugar to add, any problems in each link will affect the quality of the wine and the final taste.

To give a simple example, for example, if the ratio of adding sugar is controlled at 10:1, the brewed wine will be dry red. Wines below this number will have unpalatable bitterness due to insufficient fermentation, and wines higher than this number will be tasteless. sweet.

而加糖时也不能一次性加完，最好是发酵1~2天时先加1/20，3~4天后再加剩余的1/20。

There is also oxygenation. Most people think that grapes must not see oxygen during anaerobic fermentation, but they don’t know that if a small amount of oxygen is added at this time, it can not only shorten the fermentation time, but also improve the aroma of the wine..."

Seeing that his son said every sentence clearly and logically, Father Confucius couldn't help but believe it.
