Li Ye patted Gu Feng's shoulder and said, "You study hard, and you will leave this winemaking matter to you in the future. Today's matters are not allowed to be spread. If anyone present is spread, I will not be spared."

Everyone nodded and responded, and then Li Ye began to instruct Gufeng what to pay attention to when brewing wine. Of course, he would give it to him many times later, and it was impossible to give it to him once or twice. Although Gufeng was an old man, he was as focused as a primary school student at this time.

In fact, there are two concepts for any product production, namely experimental production and large-scale production. If a product wants to influence the market and enter people's lives, it is necessary to change the status quo on a large scale.

This is like steel. If you say when there was steel, then as early as the sixth century BC, there was a record of steelmaking in China's Spring and Autumn Period and Warring States Period. However, steel has never achieved large-scale industrial production in China for thousands of years, so it has not changed China.

Until the rise of the capitalist power led by Britain, large-scale industrial steel production drove the era of giant ships and cannons and became the world hegemon. For a long time, steel production even became the standard for Western powers to measure a country's national strength.

For example, oxygen production, the laboratory will tell you to heat potassium permanganate, but this method cannot be produced on a large scale because the cost is too high and the efficiency is too low. This method is like the most primitive steelmaking method, which can produce steel, but it cannot change anything at a large level. Making oxygen at a large scale using high pressure to liquefy the oxygen in the air and then separate it.

The reason why Li Ye used this method of making distilled liquor instead of the distillation method of heating and cooking liquor and then condensing and purifying is to solve this problem. The method is complicated in technology and huge in losses. It is OK to do experiments, but it is not possible to use it for large-scale production.

Now a wine cage can hold hundreds of kilograms of grain, and can produce hundreds of kilograms of wine at a time.

Once this experiment is successful, Li Ye can make the wine cage bigger and make more wine cages. At that time, a royal palace can produce thousands of kilograms of distilled liquor at a time! According to the cycle of grain being delivered every ten days, and a few days are used to prevent accidents, it can also be brewed twice a month.

In addition to drinking and trading, there are also medical uses, such as mosquito-proof water, perfume, and specific fuel. This is a complete and huge business chain, so Li Ye had to be cautious. He also needs many people who can make wine, not just him.

......

The entire brewing process lasted for more than an hour, and the last few jars were just light wine with a sour taste.

The wine needs to be mixed. Simply put, the wine produced in the first few jars is too high, up to about 80 degrees. It is unbearable to drink it directly. The wine produced in the last few jars is too low and it tastes sour and light.

What needs to be done is to mix light wine with high wine to achieve a suitable level of drinking. In the future, it is generally around forty to fifty degrees, but considering that people in this world may not be used to such high degrees at the beginning, and if someone treats this new wine as an old wine, it may be a problem.

So Li Ye thought it was appropriate to have about 35 to 40 degrees, and the most difficult part came. He had no measurement tools and had no idea of ​​the specific degree of wine. He could only rely on his feelings and had experience.

By shaking, you can roughly see the approximate degree of the wine by looking at the size and duration of the pile of flowers. The longer the hops exist, the lower the number of lengths.

Generally, after shaking for more than ten seconds, there will be corn grain-sized hops. If there are about fifteen seconds, then it will be about fifty degrees. If it is only the size of sorghum and less than three seconds, it will exceed sixty degrees. But if you want to be more precise, you can't.

Li Ye had to slowly blend and taste it once, because he was afraid that his hands would slip too much and the movement would be weak.

It took him a whole afternoon, and under the curious onlookers, he finally blended out seven jars of distilled liquor suitable for drinking about forty degrees. There were a total of 105 kilograms, so that the servants could seal it and preserve it carefully. However, he did not blend the jar with the highest degree at the beginning, but stayed alone.

Li Ye tasted the jar and it should be about 80 degrees, so it was too wasteful to use it to mix wine.

After brewing the wine, the fire was reduced and the sky pot was taken off. The grain in the wine cage had turned into hot wine lees. After cooling down, Li Ye asked his servants to take it out and pile it up. This thing can be used to feed cows, pigs, and fish, but at present, the royal palace is not useful.

Li Ye finally checked the bottom pot, wine cage, wine tank, and sky pot before he felt relieved. With this experiment, as long as he followed this blueprint, distilled liquor could soon achieve large-scale production.

Li Ye was so happy that he worked hard for a day and was in the steaming brewing room again. After busyness, he was already sweating all over. He asked Gu Feng to take his servants to pack up his things, clean the wine cage and the pot, and he was going to take He Qian back for dinner and then have a good sleep.

At this moment, someone told him that Duke De was coming.

.....

This time, Degong still came with Gillian and brought a gift, an exquisite small box with red silk inlaid bottom, with golden nuggets inside. Degong said it was 100 taels, 100 taels were about 6 pounds, which was a big gift!

One tael of gold is worth ten taels of silver, and the quality is better, and the gold is easy to store. The actual value of one tael of gold is only more than a thousand taels of silver.

"Dong De, why are you so polite? You don't need to give such a heavy gift if you come." Li Ye said, asking Yue'er to put it away quickly. He wanted to start producing distilled liquor on a large scale and build a hydraulic drive system. He would use more money in the future.

"Ha, you guys are just kind." Degong shook his head and smiled.

"What's the point? My family is a little poor recently. I can't get polite if I want to be polite." Li Ye said while asking Qiu'er Yue'er to bring incense tea. He Qian also came over and greeted Jiao. Somehow, she was happy for the afternoon and suddenly became depressed and sat aside without saying a word.

"I'm not here for nothing. Last time, Tang Zhou mentioned your master's skill in planning to the emperor in the palace, so his Majesty wanted to take the exam for you, but it was not convenient for him to leave the palace. So he asked Zu Yi from the Hanlin Bachelor's Academy to give a question and asked me to come and take the exam for you specifically, so he didn't have to be favored."

Li Ye was amused and crying. Tang Zhou was really a good thing and was causing trouble for him. If he had known this, he would not have helped him.

Duke De solemnly took out a few pieces of white paper from his arms, with the emperor's imperial paintings on it, with dense topics written on it. Li Ye took it over and said, "Qiu'er, please help me."

"No!" De Gong blew his beard and glared: "This is the emperor's imperial order. No way you are as casual as you. Even if you think it is simple, you have to do it yourself, otherwise you will be deceiving the emperor."

"I'll grind the ink for the prince." Gillian, who had been shy, took the opportunity to speak at this time.
