Otaku Engineer in Great Tang Dynasty Chapter 106: Bartending (Part 2)

　　 Li Mansion, West Yard.

　　In a makeshift simple workshop, the iron eggs are burning, and Li Zexuan is pouring white wine into the distilling pot and paying attention to the temperature in the pot.

　　"Master, can you get stronger wine by heating this wine?"

　　 Tie Dan asked curiously.

　　 Li Zexuan sees that there is just time now, so he popularizes scientific knowledge for himself, a cheap apprentice.

　　 "Just heating, of course, you can't get stronger wine, iron eggs, have you ever boiled water before?"

　　 "Well, of course I burned it."

　　"Then have you discovered that after boiling the water, if you continue to boil it, the water in the pot will become less and less?"

　　 "Well, Master, that's true."

　　 Li Zexuan nodded and continued: "Actually, the reason why the wine we drink now is not strong is because there is too much water in it and too little alcohol. Oh, Master calls the intoxicating things in the wine alcohol. What Master has to do now is to steam out the water in the wine to make the wine more concentrated, do you understand?"

　　 Tiedan nodded thoughtfully, and then wondered: "Then Master, will you steam the alcohol together?"

　　 Li Zexuan exclaimed: "Tiedan, you have a good question. This is the most important part of distilled wine. In fact, compared to water, alcohol is more volatile at lower temperatures.

　　um, in other words, if they are steamed together, the alcohol will be steamed out first, and then we will add a tube flushed with cold water at the back, and the alcohol will become liquid when it gets cold. Do you understand? "

　　The boiling point of alcohol is about 75 degrees. The temperature must fall below 75 degrees to liquefy. The evaporation rate is very fast at about fifty degrees. Therefore, the condensed alcohol should be cooled to below fifty degrees in the condenser tube. Generally, it will be cooled to about 30 degrees. Flow out. Of course there are also lower cooling temperatures.

　　 Tiedan shook her head in confusion, and said, "Master, you understand the iron egg that you mentioned earlier, but later you said that the volatile alcohol became liquid when it entered the tube. This iron egg didn't quite understand it. "

　　 Li Zexuan patted his forehead, but he had no choice but to explain to Tiedan the knowledge of junior high school physics that the solution vaporized when heated and the steam liquefied when cooled. Tiedan understood.

　　"Okay, don't be distracted. You have a lot to learn in the future. Now concentrate on burning the fire and pay attention to the heat."

　　 "Yes, Master!"

　　............

　　 Two quarters of an hour later, the thin tube of the condenser finally started to slowly flow out the concentrated liquor, and suddenly a strong smell of wine filled the whole room.

　　 "Wow, it smells good, Master, this is much more aromatic than my father's usual wine."

　　 Tie Dan sniffed his nose vigorously and said excitedly.

　　 Li Zexuan smiled slightly and couldn't comment.

　　"Xiaoxuan, what kind of wine is this so fragrant?"

　　 Cheng Chumo outside the house, smelled the strong aroma of wine, no matter where he could stand it, he immediately rushed in. This guy didn't know how to write the word polite, and he was about to come up and take away the condensation while talking. A wine jar under the tube to receive wine.

　　Li Zexuan quickly blocked:

　　"Stop, this new head wine is poisonous, you can't drink it!"

　　 This product is really terrible. Although the freshly distilled top wine is indeed high in alcohol and smells very good, it contains a lot of low-boiling substances such as aldehydes, esters and ketones. If you are blind, you will die.

　　Chu Cheng did not believe: "How can there be poison in the wine, don't lie to me, don't you kid, give me a taste, don't be so stingy!"

　　 Li Zexuan was too lazy to take care of this rambling, he saw that the top wine flowing out was more than two catties, so he changed the top of an empty wine jar, lifted the jar containing the top wine, and prepared Drained.

　　 Cheng Chu silently saw his intentions, and jumped anxiously behind him. If he couldn't beat Li Zexuan, he would definitely grab it.

　　 Li Zexuan poured the first wine into the yard, Cheng Chu stood there silently, sniffing the scent of wine remaining in the air, and muttered with a pity: "Prodigal, prodigal!"

　　 Li Zexuan ignored him and turned back to the house.

　　 An hour later, Li Zexuan brought out a jar of high-concentration wine and put it on the table next to Han Yuxi. He looked at Han Yuxi and asked: "Yuxi, how is it? Have you figured out the ratio of the ingredients? "

　　 Han Yuxi nodded, pushed a glass of red wine, and said: "Master, after I tried it many times, I found that the wine with this combination is easier to drink. You can try it!"

　　 Li Zexuan looked at the wine and hesitated, Han Yuxi smiled and said, "Master, don’t worry, this wine is not intoxicating."

　　 Li Zexuan picked up the glass and took a sip. The entrance has the sweet and sour of shanguo. After a careful tasting, there is also a hint of wine, mellow and sweet. Li Zexuan nodded with satisfaction. Han Yuxi is indeed a genius in making wine. , I just gave her a list of raw materials, and she actually figured out the ratio of various raw materials by herself, which is really amazing.

　　"Well, not bad, Yuxi, you are really amazing, just adjust it according to this ratio!"

　　 Han Yuxi heard Li Zexuan's praise, and immediately felt that her hard work was worth it, and she quickly agreed in a low voice, and then continued to mix the drinks.

　　 At this time, Cheng Chu came in silently and glanced at Li Zexuan with a pity, then he suddenly caught a glimpse of the cocktail prepared by Han Yuxi, and he was energetic, he cried:

　　"Miss Han, is this the new wine you made? Let me, the master wine taster, help you taste it!"

　　 Han Yuxi couldn’t help but smile, Li Zexuan had nothing to do with this cheeky~IndoMTL.com~Cheng Chumo poured a cocktail by himself, and then put it in his hand and exclaimed:

　　 "Well, it's not bad just to look at it, girl Han, Xiao Xuan is really lucky to find you."

　　's words are a bit ambiguous, Han Yuxi's face blushed, Li Zexuan glared at him, and said in a bad mood: "Quickly drink, the wine can't stop your mouth!"

　　Cheng Chu Mohaha smiled, picked up the wine, took a sip, smashed his mouth, then drank it again, seeing Cheng Chumo sighed:

　　"Miss Han, the taste of your wine is very novel. I have never drank such a wine before. Well, it tastes very good anyway. But it’s a bit boring, not as good as the ones that Xiaoxuan poured out just now. Wine."

　　Han Yuxi smiled and said: "Master Cheng, this wine can also be served with strong, you can wait a moment."

　　 Li Zexuan saw that Han Yuxi was starting to drink again, so he grabbed Cheng Chu silently and said, "Ugly cow, come and help me move something!"

　　 "Uh, you won't ask your servants to help you?"

　　 "Eat people's mouth is soft, and the hand is short, have you heard of it, come with me if you want to drink wine."

　　 Cheng Chumo could only follow in surprise, dare to make Lu Guogong's son the servant, Li Zexuan is no one.

　　 Li Zexuan asked Cheng Chumo to come here to help him carry a bag of saltpeter, although this thing is not heavy, but there is this free labor that does not need to be used in vain, lest the goods are idle there again. Four.

　　 Last night, Li Zexuan asked his father to help him buy a few saltpeter mines, and he didn't know what happened to his father.

　　 Li Zexuan wants to make some ice cubes, a strong cocktail. If you don’t add ice cubes, it will be too stomach-burning to drink. If you have ice cubes, it will be more refreshing to drink.
