Zhu Di said it, and the other three princes and several officials in the palace showed a look of reminiscence.

What the officials thought was: yes, the vinegar of the dumplings last time was that color, not white, yellow, black, isn't that vinegar from elsewhere? It's normal!

"Taste this vinegar." Zhu Di asked the officials to use the current vinegar.

Officials don't care, it's not that they don't eat it, it's like this with local vinegar.

Dip the dumplings and eat a bite, aftertaste, the six people look at each other, the taste is different, how to say, in some places it is better than that day's vinegar, but in other places it is not as good as that day's vinegar.

"Vinegar, black, good, white, um! Hey, hey, hey, hey......" Zhu Wentian was there, and finally couldn't help laughing.

He looked at the expression of the officials in Taiyuan Mansion and thought it was interesting, the current vinegar has three colors, the normal one is white, and then there is a light yellow one, and the light yellow one is obviously not good enough.

Then there is the red one, and the red one is made with red yeast rice, which belongs to rice vinegar.

Black vinegar was originally a thing in Qingyuan County, and it was only available in the Qing Dynasty in history.

The brewing method has changed, especially the fermentation method, which used to be white, and the vinegar that comes out is naturally white.

Red yeast rice vinegar has two red pastries, and there are also white pastes involved, and the last one that comes out is red vinegar.

The local Shanxi aged vinegar uses the smoking process, which is the same as the red yeast vinegar, and is poured with a simmer and smoked.

The finished vinegar is black, and the black one is naturally different in taste due to the smoking process, just like smoked chicken and smoked sausage.

As for the dog days and the three nine ice fishing, this is a means to control the microflora, and the bacteria can reproduce better under extremely cold and hot conditions.

Just as many crops taste good when grown in places with large temperature differences, rice is one of them.

When I was in Xiaqiu Village, I made this process by myself, but there was no Sanjiu to fish for ice, and the ice at that temperature in the south of the Yangtze River was too pitiful, a thin layer, and the sun rose and disappeared, unless I found a mountain at a high altitude to deal with vinegar.

Due to the short time, there is not such a long period of precipitation, and now the oldest is only more than three years.

The vinegar sold by Jubiqi is not this black, it is aged vinegar purchased from other places, plus new vinegar, new vinegar is cheap, and old vinegar is expensive, including red yeast rice vinegar.

When eating, the local white vinegar is aged, and it is good in some aspects, and the taste is not smoked, and it is a little worse than the black one.

If you replace the aged one with a smoked one, it is an authentic Shanxi old vinegar.

Today's eating dumplings in Qingyuan County is deliberately arranged, since it is people's vinegar, it will be returned to others, and there must be official participation.

There are many people in the official money, and they can brew millions of catties at a time, extract grain from other places, burn a lot of large vinegar jars, and wait for a few years to eat it slowly.

Brewing smoked vinegar year after year, five years later it will be five years old, eight years, ten years, and fifteen years......

If you don't brew it, you won't have it, and if you brew it, you won't delay anything, and when the child who is born has a child again, the first batch of aged vinegar will be twenty years old.

When the taste is not noticeable to ordinary people, there is no difference between it and ten years, it seems to be no different.

In fact, what you eat is no longer vinegar, it is years, that is, vinegar that is shorter than other years, and I do not accept refutation.

Of course, there is a technique that simulates the taste of aging by blending part of the vinegar and part of the blending vinegar with something else added.

If you are a little more ruthless, the science and technology will be ruthless, and a little old vinegar will not be put away, and it will be hard blended through glacial acetic acid.

Wine can be blended with ethanol to bring out the taste of aging, and vinegar should not be different.

When Zhu Wentian was thinking about it, the lieutenant chief said this aspect, he only talked about the process, not the history, and he didn't know.

"Yes, the black we eat is from Xiaqiu Village, how do we know that there is no black vinegar in the entire Ming Dynasty except for Xiaqiu Village."

Zhu Li reacted, black is good, if it is a long time, how much does it cost a catty?

Zhu Li, who was happy, suddenly paused again: "Captain, now they all say that they want to protect the ownership of technology, and the technology of our village's black vinegar ......"

"Your Highness, due to the large number of people required to make vinegar, it is impossible to keep it completely secret at all, unless it is blocked.

It's not worth doing that to eat, and if someone else learns it and goes to other places to make it, you can't go around arresting people.

It's better to set a rule, Xiaqiu Village has a technology, and in the future, all the places where this technology is used to brew old vinegar, the people of Xiaqiu Village are not allowed to charge money when they are jealous in the past.

refers to the brewery, not to go to someone else's shop to take other people's aged vinegar and not give money, that is to rob. ”

The chief waved his hand, didn't want money, gave it, Han Han said, this has nothing to do with patents, it involves people's livelihood, if you insist on it, the reputation that Xiaqiu Village has finally established will be ruined.

The kind of technology that can make a lot of money in the industry is charged, and the small technology that is easy to learn is difficult to control.

For example, Shu Di used a small technology, someone saw it, sent the news back, sent people to inspect it, and found that it was indeed the local yamen report official.

In the end, the lawsuit was won, and that little skill would at most provide a living allowance for the craftsman, and he couldn't get back the money he tossed if he was killed.

Zhu Li nodded vigorously: "Li Changyi, this is free to be jealous in any workshop that uses the same technology to brew aged vinegar, let's go back and ask my father to give an order." ”

He looked solemn, in fact, he and his brother both knew that how could people in Xiaqiu Village be jealous of other people's workshops? Isn't there one in the village?

The key is that it is really in the past, without mentioning technology, others are willing to give, and it is good publicity after giving it! The ancestor who brewed this aged vinegar came, which means that our aged vinegar is good.

"Your Highness praises me." As he spoke, he pulled out a stack of paper from his bosom, on which the entire brewing process was written.

Don't just look at it, the brewing method is black, and the steps are complicated!

This includes temperature, concentration, sealing, and more.

Moreover, making vinegar is the same as winemaking, and when it is placed normally, the longer the year, the higher the degree, a lot of water goes out, and the microorganisms continue to ferment.

The real 20-year-old vinegar of Shanxi is cherished when eating, and it will not be like the people who dip dumplings and eat jealousy now, and they can't drink it directly.

Zhu Li took a stack of papers: "This ......"

"Second brother, ask if there is a vinegar workshop in the local area, if there is a word for them, tell them the cause and effect, and then you will send someone to supervise the construction of a larger vinegar workshop.

After three years, it will be able to have the same texture and taste as Xiaqiu Village, and then pay tribute to our father, so that Taiyuan Mansion has one more profitable business.

Let's also ask someone to copy a copy and send it to Xi'an Mansion, so that it can be brewed there, and the vinegar brewed by different crops and different water is also different. ”

Zhu Fan gave an idea, and by the way, he took the benefits, and a large amount of old vinegar came out in the future to make money together.

"Done! Eat first, bring some of our vinegar, and eat it in comparison. ”

Zhu Li didn't refuse, anyway, it wasn't his technique.
