Headache, really painful.

Perhaps it is because the liquor refined by Zhang Qian himself has many more impurities harmful to the human body than the liquor produced on a large scale in later generations. Maybe it's because I have toasted too many times with Wang Han, Zhang Xu, and Wang Zhilian, these Tang wine fairies. On that day, Zhang Qian didn't even remember how he returned home in the end. I slept on the bed until noon the next day, and finally regained some consciousness.

However, his head hurt as if he had been cut by an axe, and when he moved, the world spun around.

However, he did not dare to sleep again. first asked Zijuan to help him get a decanting soup to deal with the numb stomach that warmed up. Then he cheered up, and with the support of Zhang Yi, a family member, he went to the flower water workshop.

The large copper kettle in the workshop is using the "water bath heating-condensation" method to distill the essence (alcohol) of the distilled liquor from the purchased rice wine. And because the condensation is not thorough enough, the whole workshop is wafting with the smell of inferior pots in later generations. Exposed to alcohol vapor for a long time, including Ren Cong and Guo Nu, everyone present had a red face and a little big tongue when they spoke.

"Teacher, senior brother has woken up?" Seeing that Zhang Qian personally came to "supervise his studies", Guo Nu staggered forward to greet him with an attitude ten times more polite than that of later graduate students when they saw their tutors, and asked for warmth.

"Wake up, hurry up and open the window, who told you to close the workshop window?!" Seeing that the other party was about to crash into his arms, Zhang Qian hurriedly stabilized Guo Nu's body, "Ren Cong, don't be busy adding rice wine to the pot first, and lead someone to push all the windows open." Remember, you will work with the windows open in the future, so don't be bored again! ”

After speaking, letting go of Guo Nu, Zhang Qian quickly turned his head, pushed open the door of the house, and gasped for breath in the cold autumn wind, while rejoicing in his heart.

Thanks to Lao Tzu coming in time, otherwise, Ren Cong, Guo Nu and the guys in the workshop would have to be poisoned by alcohol today! And in case of sequelae, it is not easy to find such an obedient "graduate student". The medical alcohol that was promised to be sent to Zhang Ruoxu's house today had to be missed.

"Teacher, senior brother. It's cold, the windows are open, the wine is hot slowly, and you can't steam much for a long time! ”

"Taste, smell wafted all over Zhuangzi. I'm afraid that if I open the window, others will be able to see what we're doing from afar! ”

Ren Cong and Guo Nu didn't feel the danger at all, and both came over and gave drunken advice.

"It's okay, arrange for the family to patrol the surroundings, and don't allow idle people to come within forty feet of here." Zhang Qian shook his head decisively and continued to give orders, "Also, when refining alcohol, there is no need for so many people in the workshop. One looks at the fire, the other stares at the water level and the position of the wine, and the other is specifically responsible for receiving the alcohol. The extra people are divided into three classes. After that, it rotates every two hours. The two of you, every day by the medicine refining pot, the total stay time must not exceed three hours! ”

It's never too late to make amends! While the toilet water has not yet been put into large-scale production, it is better to set the rules for shift rest first, than to grit your teeth and work for a short time after seeing high profits in the future.

In addition, the entire alcohol production process is not too technical, and there is really no need for Ren Cong and Guo Nu to stare at it day and night.

Thinking of this, Zhang Qian quickly added, "Open the window, after the guys divide the shifts, the two of you will bring a barrel of alcohol with the most distillations and follow me to the study." I'll teach you how to measure the purity of the alcohol, and by the way, I will bring out a bucket for wound cleaning. ”

"Hey, hey! Got it! Yes, senior brother, we're good, we're good! "Hearing that there are new skills to learn, Ren Cong and Guo Nu can no longer care about arguing with Zhang Qian about the disadvantages of opening the window. Lian Sheng agreed to carry out the arrangement of the senior brother.

"Later, if you still have time, find a craftsman to order another one, forget it, and then order three copper kettles." Let's refine the four copper kettles together, and the alcohol will naturally be faster. Turning around and quickly scanning the number of guys, Zhang Qian took a deep breath and continued to add. lest anyone miss his turn to work. If there are not enough manpower in the future, I will draw a family from my Zhuangzi! ”

Liushen Flower Dew is positioned at the high-end, and the output does not need to be too large, and the production capacity of a copper kettle is rich. However, after yesterday's chrysanthemum feast at Zhang Ruoxu's house, Zhang Qian estimated that he would soon have to establish the second industry after coming to Datang, the soju trust. So, you have to plan ahead!

Unlike the Rokushin Flower Dew, once the liquor is on the market, I am afraid that the demand will soon rush to an astronomical amount. And the production process of liquor must not be kept secret for too long. In Datang, which has no patent law, if you want not to be defeated by competitors, in addition to relying on the government, the best way is to fight for quality and production capacity.

In other words, in a short period of time, the more alchemy pots were erected in Zhangjiazhuang, the more skilled workers were trained. And the more skilled workers are trained, the better the quality of the liquor and the higher the output. After all, the entire brewing industry in Datang is still in a very primitive stage, and in a short period of time, there will definitely be no high-end goods such as Moutai and Wuliangye.

Thinking about it this way, I am afraid that there is still a big gap in the number of servants and tenants in the entire Zhangjiazhuang who have become employees of the distillery. And if all the manpower is invested in the distilled spirits industry, there will be no one to grow food next year. Next, the stable supply of rice wine will also become a huge hidden danger......

If you make rice wine as a raw material yourself, I am afraid that some of the slaves and tenants of the Ren family and the Guo family will also have to be brought in. In that case, the personnel problem would have been solved, but the food shortage would have been even greater. Then we will face a series of new problems such as the abandonment of fields, the safety of workers' production, and the solution of accommodation and food.

Everything is afraid to think deeply, and the more he thinks about it, the more Zhang Qian feels a headache. The whole person became distracted, until his feet stepped into his study, and he still had not broken free from the "sleepwalking" state.

Fortunately, Ren Cong and Guo Nu were also dizzy from the alcohol vapor, and they had long been used to it, and the senior brother often wandered outside the world. After arriving at the study, the two put down the wine barrel first, and then they went to the servant to ask for tea and snacks. It wasn't until he drank the whole two pots of strong tea into his stomach with dim sum that he glanced at Zhang Qian, who already knew how to take the tea and taste it slowly, and cautiously reminded: "Senior brother, you said today that you would teach us to measure the purity of alcohol......

"Yes, let us take the liters of grain and the scales for the rice, and use them as utensils." Zhang Qian quickly put down the teacup and instructed with a smile, "You go to the housekeeper first to get the weighing plate and the liter." By the way, let someone get another bucket of water! ”

"Yes!" Ren Cong and Guo Nu agreed and hurriedly went out. Taking advantage of the fact that no one was disturbing, Zhang Qian took out a hand-held computer from the depths of the bookcase, called up the calculator, took out a roll of white paper and charcoal, 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 1000 kilograms per cubic meter. In later generations, the standard of medical alcohol was 75 percent. The measuring tool can't be too accurate, and the well water is not pure water, so Zhang Qian can only ensure that the alcohol concentration reaches 70% to 75%, even if it is done.

In this way, it's simple. Take an intermediate number, and the density per cubic meter is around 860 grams. As long as the weight is eighty or six of the same volume of water, it can barely reach the standard.

So, when Ren Cong and Guo Nu were two, they returned happily with water and measuring tools. Zhang Qian has already designed the entire measurement process on paper. With the help of the two juniors, he operated and explained at the same time, and it took less than a quarter of an hour to measure the purity of the alcohol after the fifth distillation. It is as high as 2 out of 80, which has far exceeded the medical standard.

It is difficult to refine, and it is extremely simple to reduce the concentration. According to the calculated number, add distilled water directly to it. This is still Zhang Qian's conscience, otherwise, it is estimated that there will be no big problem if he directly adds river water.

So, the three brothers returned to the workshop again, temporarily stopped the great business of steaming wine, first vacated the medicine refining pot, tossed out a large barrel of distilled water, and then, according to the proportion, added the distilled water to the previous barrel of "five distilled wine", re-measured, and repeatedly confirmed that the numbers were about the same three times, and the first barrel of medical alcohol in Datang was announced.

He personally escorted the carriage, and together with Ren Cong, Guo Nu, and Ren Quan, he sent the entire barrel of medical alcohol to Zhang Ruoxu's house, and the sky was dark. repeatedly declined the invitation of the elders to stay for supper, Zhang Qian said goodbye, dragged his tired body, and embarked on the road home with everyone.

Although I was so tired that the bones of my whole body were almost scattered, and my stomach was so hungry that I kept beating the drum. But the headache symptoms after being drunk have disappeared completely. Taking advantage of the fact that the night breeze was not too cold, Zhang Qian stretched his arms, moved his thighs, and did a few preparatory actions before free fighting while walking, and unconsciously, he felt a little peaceful in rural life.

However, this tranquility only lasted less than half a pillar of incense, and it was shattered by the neighing of horses.

Six carts pulled by two horses, in the twilight, drove quickly to his door.

On the carriage that was specially used for people to ride, there was a white and pure fat man who pushed the car door, followed Lao Yuan, and waved his hand vigorously to Ren Cong, "Little Five, Little Five, the foolish brother has come to see you." The glass bottles you want are all in the carriage behind. The foolish brother is afraid that you will not be enough, so he will double it for you, and the price will be exactly the same as what was originally said, and all these extra bottles will be given away for nothing! ”

"It's Wang Liuli who personally sent the bottle, senior brother, I'll pick him up!" For many days in a row, watching the six gods make more and more flower dew, but the bottle containing the flower dew has not arrived, Ren Cong's heart has long been anxious. At this moment, seeing that the bottle had finally arrived, he turned his head and whispered to Zhang Qian, and then rushed towards the carriage, "Thank you, Brother Wang, I didn't expect you to come in person!" If you miss the distance, you can still hope for ......"

"If the family doesn't talk to two families, Xiao Wu should be polite!" Although Wang Yuanbao is fat, his movements are extremely flexible. jumped out of the carriage and grabbed Ren Cong's arm with both hands, "As long as it doesn't delay your business, Xiao Wu, you come with me, on the last carriage, my brother has prepared other treasures for you!" ”

As he spoke, he dragged Ren Cong to the last carriage, and quickly lowered his voice, "You said that your master likes chicks who are flat in front and back, but I remember it in my heart for my brother." Come, come, you first see if it's what your master likes. The first time I came to his Zhuangzi to meet him, I couldn't get a gift for my brother, so I specially collected the twins from Renyazi's hands! It's a lot of effort! Still, it's definitely worth the money! The two of them, piano, chess, calligraphy and painting are specially trained, whether they go out with them or stay at home to warm the bed, they are guaranteed not to disappoint your master! ”
