A headache, it hurts really.

Perhaps it was because the liquor that Zhang Qian himself refined had more harmful impurities than the liquor produced on a large scale in later generations. Perhaps it was because he raised his glasses with the Tang Dynasty wine fairies such as Wang Han, Zhang Xu, and Wang Zhihuan too many times. On that day, Zhang Qian didn't even remember how he finally returned to his home. He lay on the bed and slept until noon the next day, and finally recovered from a little sober.

However, his head hurts as if he is being chopped by an axe. When he moves, he will turn dizzy.

However, he did not dare to sleep anymore. He first asked Zijuan to help him get a sobering soup, which made him warm his numb stomach. Then he cheered up and went to the Hualushui workshop with the help of his servant Zhang Yi.

The large copper pot in the workshop is adopting the "water bath heating-condensing" method to distillate the essence of the wine (alcohol) from the purchased rice wine. Because of the incomplete condensation, the entire workshop is filled with the smell of inferior pots from later generations. After a long period of exposure to alcohol steam, including Ren Cong and Guo Nu, everyone present has a red face and a little big tongue when talking.

"Teacher, have you sober up?" Seeing Zhang Qian coming to "supervise his studies", Guo Nu staggered forward with a ten-fold polite attitude than later graduate students who met his supervisor.

"Wake up, open the window quickly. Who told you to close the workshop window?!" Seeing that the other party was about to crash into his arms, Zhang Qian quickly helped Guo Nu's body firmly. "Ren Cong, don't rush to add yellow wine to the pot first, and lead people to push all the windows open. Remember, if the windows are opened in the future, don't be bored anymore!"

After saying that, letting go of Guo Nu, Zhang Qian quickly turned his head and pushed open the door. He was panting heavily in the bitter autumn wind while being very grateful in his heart.

Fortunately, I came in time, otherwise Ren Cong, Guo Nu and the guys in the workshop would have to be poisoned by alcohol today! If there were sequelae, it would be difficult to find such an obedient "graduate student". Today, the medical alcohol that promised to be sent to Zhang Ruoxu's family would have to break the appointment.

"Teacher, senior brother. It's cold. The window is open. The wine is hot slowly. It's not too much to steam for a long time!"

"The taste is floating all over the village. I am afraid that if the window is opened, others can see how we are making Liushen Hualu from a distance!"

Ren Cong and Guo Nu, but they didn't feel any danger at all, followed them and gave drunken advice.

"It's okay, arrange for servants to patrol around, and do not allow idle people to approach this place within forty feet." Zhang Qian shook his head decisively and continued to issue orders. "Also, when refining alcohol, there are no need for so many people in the workshop. One should watch the fire, the other should stare at the water level and the location of the wine, and the other should be responsible for receiving alcohol. The extra people will be divided into three shifts. From now on, they will be rotated every two hours. You two will stay next to the refining pot every day, and the total stay time must not exceed three hours!"

It is never too late to repair the dead! Before the flower dew is put into production on a large scale, it is better to set the rules for resting shifts first than to see high profits in the future, and then grit your teeth and shorten the working time of workers.

In addition, the entire production process of alcohol does not have much technical content, and there is no need for Ren Cong and Guo Nu to stare at each other day and night.

Thinking of this, Zhang Qian quickly added, "Open the window and after the shift was sorted, you two took a bucket of alcohol that had been distilled the most frequently and followed me to the study. I will teach you how to measure the purity of alcohol and make a bucket of alcohol by the way, as a special purpose for cleaning the wound."

"Hey, hey! I understand! Yes, senior brother, we are all right, that's all right!" Hearing that he had new skills to learn, Ren Cong and Guo Nu no longer cared about the disadvantages of arguing with Zhang Qian about opening the window. He agreed repeatedly and went to carry out the arrangements of senior brother.

"If you have time later, find a craftsman to order one. Forget it, go and order three copper pots. Let's refine the four copper pots together, and the alcohol will naturally be faster." Turning back and quickly swept the number of people, Zhang Qian took a deep breath and continued to replenish. "Stop some people's turn to work. If there is not enough staff in the future, please draw servants from my farm!"

Liushen Hualu is positioned at the high end, and the output does not need to be too large. The production capacity of a copper pot is more than rich. However, after the chrysanthemum appreciation feast at Zhang Ruoxu's family yesterday, Zhang Qian estimated that he would soon have to establish a second industry after the Tang Dynasty, a soju trust. Therefore, he had to prepare for it!

Unlike Liushen Hualu, once the liquor is launched, the demand will soon reach an astronomical figure. The production process of liquor will definitely not be kept confidential for too long. In Datang, which has no patent law, if you want to avoid being defeated by your competitors, in addition to relying on the government, the best way is to compete for quality and production capacity.

In other words, in a short period of time, the more pharmacy pots are erected in Zhangjiazhuang, the more skilled workers will be cultivated. The more skilled workers are cultivated, the better the quality of the liquor and the higher the output. After all, the entire Datang winemaking industry is still in a very primitive stage. In a short period of time, there will definitely be no high-end products such as Moutai and Wuliangye, at most, there will be several street stall vodkas, and the highest-end level can reach Erguotou!

Thinking about this, if the slaves and tenants in Zhangjiazhuang are turned into distillery employees, there may still be a big gap in the number of people. If all the manpower is invested in the distilled liquor industry, no one will grow food next year. Next, the stable supply of rice wine will also become a huge hidden danger...

If the rice wine used as raw materials is brewed by oneself, some of the slaves and tenants of the Ren and Guo families would have to be brought in. In that case, the personnel problem would be solved, but the food gap would be larger. Then, the fields would be abandoned, the worker's production safety, accommodation and food would be solved, and a series of new problems would be faced with a series of new problems.

I was afraid of thinking deeper into everything. The more I thought about it, the more I felt a headache. I became unconscious. Until my feet stepped into my study, I still had not escaped from the "sleepwalking" state.

Fortunately, Ren Cong and Guo Nu were also dizzy by the alcohol steam, and they had long been used to it. The elder brother often wandered around. After arriving at the study, the two of them put down the wine barrels first, and then they were familiar with it. They each asked the servants to ask for tea and snacks. It was not until they drank the two pots of strong tea into their stomachs that they took the snacks into their stomachs. They looked at Zhang Qian, who knew that they had picked up the tea and tasted it slowly, and carefully issued a reminder: "Senior brother, you said today that you would teach us to measure the purity of alcohol..."

"Yes, let's take the lepsy that holds the grain and the scale that buys rice as utensils." Zhang Qian quickly put down the teacup and said with a smile, "You go to the butler to get the weighing plate and lepsy first. By the way, let's get a bucket of clean water!"

"Yes!" Ren Cong and Guo Nu agreed and hurried out. While no one was disturbing, Zhang Qian took out a mobile phone from the depths of the bookcase, called out a calculator, took out a roll of white paper and a charcoal pen, and began to preview the entire calculation process by himself.

The density of pure alcohol is 789 kilograms per cubic meter, while the standard density of water is 1,000 kilograms per cubic meter. The standard for medical alcohol in later generations was 75%. The measuring gauge could not be too accurate, and well water was not pure water, so Zhang Qian could only make a simple decision to ensure that the alcohol concentration reaches 70% to 75% and is completed.

This is simple. Take an intermediate number and the density per cubic meter is around 860 kilograms. As long as the weight is 86% of the same volume of clean water, it can barely meet the standard.

So, when Ren Cong and Guo Nu returned excitedly with clear water and measuring gauge. Zhang Qian had already designed the entire measurement process on paper. With the help of the two junior brothers, he operated and explained. In less than a quarter of an hour, he measured the purity of alcohol after the fifth distillation. It was as high as 82%, which was far beyond the medical standards.

It is difficult to refine, and it reduces the concentration, but it is extremely simple. According to the calculated numbers, just add distilled water directly into it. This is Zhang Qian's conscience, otherwise, adding river water directly will probably not be a big problem.

So, the three brothers returned to the workshop again and temporarily stopped steaming wine. They first vacate the refining pot and made a large bucket of distilled water. Then, they added the distilled water to the previous barrel of "Five Steamed Wine" in proportion, measured it again, and after repeatedly confirming that the numbers were almost the same, the first barrel of medical alcohol in the Tang Dynasty was announced to the world.

He personally took the carriage and sent the whole bucket of medical alcohol to Zhang Ruoxu's house with Ren Cong, Guo Nu and Ren Quan. The sky turned dark. He repeatedly refused the invitation of the elder to have a midnight snack. Zhang Qian said goodbye, dragged his tired body, and embarked on the road home with everyone.

Although he was so tired that his bones were almost dispersed and his stomach was so hungry that he kept beating the drums. However, the headache symptoms after being drunk had disappeared completely. While the autumn wind was not too cold, Zhang Qian stretched out his arms and moved his thighs. While walking, he did a few preparatory moves before free fighting. Unconsciously, he felt a bit of peace of pastoral life.

However, this peace lasted less than half a stick of incense, and was shattered by the neighing of a horse.

Six large carts with double horses quickly drove towards his doorstep in the twilight.

On the carriage that was first specially used for people to ride, a white and clean fat man pushed open the car door and waved hard to Ren Cong, "Xiaowu, Xiaowu, Brother Yu is here to see you. The glass bottles you want are all on the carriage behind. Brother Yu is afraid that you are not enough, so he doubled the price for you. The price is exactly the same as the original one. All the extra bottles will be given for free!"

"It was Wang Liuli who personally delivered the bottle. Senior brother, I'll pick him up!" After watching the Liushen flower dew more and more, but the bottle containing flower dew was delayed. Ren Cong was already anxious. Seeing that the bottle finally arrived, he turned his head and whispered to Zhang Qian, and then ran towards the carriage, "Thank you, Brother Wang, I didn't expect you to come in person! If you are missing, I hope..."

"If the family doesn't say two words, Xiao Wu, don't be polite!" Although Wang Yuanbao was fat, his movements were extremely flexible. He jumped out of the carriage and grabbed Ren Cong's arm with both hands, "As long as you don't delay your affairs, Xiao Wu, come with me, and brother has prepared other treasures for you in the last carriage!"

As he spoke, he dragged Ren Cong to the last carriage and quickly lowered his voice, "You said your master likes the young ones that are flat and flat, but Brother Wei remembers it in his heart. Come, come, see if your master likes it. The first time I came to his house to pay my respects, I couldn't take any other gifts from my brother, so I specially collected these twins from the hands of the man-teeth! It took the boss a lot of effort! However, it must be worth the money! Both of them have been specially trained in piano, chess, calligraphy and painting. Whether they are taking them out or staying at home to warm up the bed, they will not disappoint your master!"

The second update, I hope everyone can read it happily. Eight thousand words a day, as a newbie, I am also working hard enough. Good night, leave the votes, and keep the favorites. Drunk Drinker
