Curious, Bai Yuqi released [Reproductive Instinct] and [Furious Growth] at the yeast of White Velvet, and the result was ...... As a result, the yeast is all dead!

In the process of frantic reproduction, they eat up all the ingredients used to make koji, and the production of koji naturally fails.

After experimenting for a long time, Bai Yuqi mastered the ratio of time and materials, and successfully made the koji.

However, two small episodes led to a drastic reduction in the time it takes to make wine, and a by-product was also produced.

The saccharification reaction during brewing is actually to provide food for yeast to multiply.

After discovering that the saccharification process of the brewing material was too slow to keep up with the rate of yeast reproduction.

Bai Yuqi understood why rock sugar is often added when making fruit wine, and the emotion is to provide food for the yeast and improve the taste.

So Bai Yuqi asked people to find some sugar and prepare to add it to the fruit wine.

During this time, Kuyucheng did not refuse to come, and purchased various raw materials from various merchants, and sugar must be there.

But the problem is that the "sugar" that the disciple took was black and blackened a big lump of rough hair, and said that it was called "gray sugar".

Well, just like the salt, the production process is not up to par, Bai Yuqi even saw that the gray sugar was mixed with the fiber of this bagasse!

In ancient times, sugar was estimated to be a more precious condiment than salt, and the price was expensive, even if the quality was poor.

Ordinary people must not be able to afford to eat it, and the elite disdain to eat such low-quality things, they eat more caramel or honey.

However, in ancient times, when large-scale beekeeping was not possible and beekeeping technology was poor, the production of honey can be imagined.

So even if it is the elite class, they don't eat as much as they want, which is why there is a saying that sweetness is expensive.

After hearing that this kind of gray sugar is not a large quantity, it is often sold by southern merchants in Chang'an City, so it will be easy to do.

As long as the raw materials can be found, filtering and decolorization is not too much of a problem for Bai Yuqi, and even he disdains to use any yellow mud decolorization method.

If you eat it yourself, you can use [extraction] and [refining], and it is enough to refine some in small batches, and if you want to produce it in large quantities, you can directly use activated carbon.

With the systematic search and manufacturing process, it is not difficult to solve the material of processed activated carbon, and the leftover materials from processing bamboo products, the fired bamboo charcoal is good.

Both salt and acid can be used for activation, not to mention salt, acid...... Do you remember the [acid splash] that the system recommended to Bai Yuqi in the first batch?

As a result, in addition to the pillar industry of Daluo Yubao, Kuyucheng has an additional product called "rock sugar".

With rock sugar, even if the problem of brewing wine is basically solved, the follow-up taste improvement, new product research and development and other work will naturally be handed over to the disciples of the Lijiu Workshop to ponder, and the master will lead the door and practice in the individual.

To say, there are a lot of industries in Kuyu City.

The seven things that opened the door of "firewood, rice, oil, salt, sauce, vinegar and tea" were basically solved, and there were three more things like "sugar, meat, and wine".

Needless to say, "firewood" is all over the mountain;

Although "rice" was not cultivated and sown on a large scale, crops were already planted in the Yitian under the name of Wujimen.

Therefore, Bai Yuqi did not promote the new planting method on a large scale for the time being, and everything was planned after harvest and before spring ploughing next year.

After purchasing a large number of soybeans and other crops, "oil" was also handed over to the disciples of [Ding Yimen] to establish an "oil mill" to extract vegetable oil.

Needless to say, "salt", "sauce", since you can buy soybean oil, you can naturally buy broad beans to make bean paste, and even soy sauce.

"Vinegar" is simpler, it is called wine when it is brewed, and vinegar is called when it is sour, and the process is almost the same.

However, due to the shortage of grain in the early Tang Dynasty, Bai Yuqi had no plans to launch distilled liquor in a short period of time, so naturally rice vinegar could not be brewed, and similar fruit vinegar could still be brewed.

In this way, the seasonings available in [Ding Lingmen] have been greatly enriched, making Datang a small step forward on the road to a big foodie empire.

In general, at present, in addition to a small amount of materials that can be produced by itself, Kuyucheng basically takes the form of "processing with supplied materials".

Using the Daluo Salt Treasure produced by the Kuquan Salt Farm, he wantonly purchased materials from all over the world, and bought everything and everything.

As long as there is still a demand for salt in the ten prefectures and states of Datang, there is no need to worry about having no money to buy materials, and then the purchased raw materials will be deeply processed and then sold.

With the Wuji Gate of Zhongnan Mountain, this kind of inhumane and unreasonable acquisition behavior spread.

Merchants from all walks of life in the Tang Dynasty gathered from all directions, and traveled thousands of miles to Kuyuxian City at the foot of the South Mountain to sell all kinds of goods, and then purchased all kinds of rare Tiangong products from Kuyuxian City and sold them to the prefectures and counties of Sifang.

It is precisely because of the "acquisition department" of Kuyuxian City that everything is bought and everything, so as long as you have the ability to transport the goods, even if you pull a cart of stones thousands of miles away, the procurement department of Wujimen will accept them.

Once they have their eye on a certain product, they will even sign a long-term purchase agreement with the merchant called a "supply contract".

However, Bai Yuqi traveled through it, not to run to Datang to make money, he wanted those Kaiyuan Tongbao to have a hairy use?

He had been staying in Zhongnan Mountain to farm and develop before, mainly because the Wujimen under his name was too weak and the foundation was too poor, so he couldn't achieve his goal at all.

Therefore, instead of going out early to wave, and then encountering all kinds of problems that make people anxious, and offending the local family of Datang to make enemies of the world, it is better to develop obscenely in Kuyu City, and wait until the miracle is completed and then sweep the world in one fell swoop.

With Bai Yuqi's character, he doesn't like to play any conspiracy and tricks, to intrigue with those family lords, and when the time comes, he will make any grievances and hatreds, and make some bloody plots of happiness and revenge.

That kind of development route does not conform to his immortal personality, if you want to play, you can play with the general trend, crush any resistance force in a dignified manner, and tell them to surrender or perish with power.

This is also what he and Li Shimin said when they discussed the secret of the Star Age Palace, to be harmonious and not to be chaotic.

You give me a trust, I give you a bright future, when the time comes, you will have your imperial merits, I will accept my faith merits, and our brothers will go hand in hand to get what they need!

may be because the cake that Bai Yuqi painted for Li Shimin was too tempting, and Li Shimin didn't know why he was fooled and lame, but he really believed his words, gave him the greatest trust as much as possible, and let him let go and toss.
