Li Residence, West Courtyard.
In a makeshift workshop, Iron Egg was making a fire. Li Zexuan was pouring white wine into the distillation pot and paying attention to the temperature in the pot.
"Master, can we get stronger wine if we heat it up?"
Iron Egg asked curiously.
Li Zexuan saw that he had time now, so he decided to teach his cheap disciple some scientific knowledge.
"Of course we can't get stronger wine just by heating it. Iron Egg, have you boiled water before?"
"Yes, of course I have."
"Then have you noticed that after boiling water, if you continue to boil it, the water in the pot will become less and less?"
"Yes, Master, it's true."
Li Zexuan nodded and continued, "Actually, the reason why the wine we are drinking is not strong is because there is too much water and too little alcohol. Oh, Master calls the intoxicating thing in the wine alcohol alcohol. What Master needs to do now is to steam out the water in the wine to make the wine more concentrated. Do you understand? "
Iron Egg nodded thoughtfully and then asked doubtfully, "Then Master, will you steam out the alcohol as well?"
Li Zexuan praised, "Iron Egg, you asked a good question. This is the most important part of distilling wine. In fact, compared to water, alcohol is more volatile at a lower temperature.
Well, in other words, if we steam them together, the alcohol will be the first to come out. Then we add a pipe with cold water to the back. The alcohol will become liquid when it is cold. Do you understand? "
The boiling point of alcohol is around 75 degrees. It can only be liquefied when the temperature drops below 75 degrees. At around 50 degrees, the evaporation rate is very fast. Therefore, the condensed alcohol must be cooled to below 50 degrees in the condensing pipe. Generally, it will only flow out when it is cooled to around 30 degrees. Of course, there are also ways to cool it at a lower temperature.
Iron Egg shook his head in confusion and said, "Master, Iron Egg understands what you said, but when you said that the evaporated alcohol will turn into liquid when it enters the pipe, this Iron Egg doesn't quite understand."
Li Zexuan patted his forehead and helplessly explained to Iron Egg that the solution vaporizes when it is hot and the steam liquifies when it is cold. Iron Egg finally understood.
"Okay, don't be distracted. You still have a lot to learn in the future. Now focus on the fire and pay attention to the temperature."
"Yes, Master!"
.....
Half an hour later, the condenser's thin pipe finally began to slowly flow of concentrated liquor. Suddenly, a strong aroma filled the entire room.
"Wow, it smells so good. Master, this wine smells much better than the wine my father usually drinks."
Iron Egg sniffed at the side and said excitedly.
Li Zexuan smiled faintly, not denying it.
"Little Xuan, what kind of liquor is this? It smells so good!"
Cheng Chumo, who was outside the room, smelled the strong aroma of the liquor and immediately rushed in. This guy didn't know how to write the word "polite". As he spoke, he came up to take away the wine jar under the condenser.
Li Zexuan hurriedly stopped him.
"Stop, this first distilled liquor is poisonous. You can't drink it, Ugly Ox!"
This guy really didn't care about his life. Although the first distilled liquor had a high alcohol concentration and smelled very good, it contained a large amount of aldehydes, esters, ketones and other substances with low boiling points. Drinking these substances could cause blindness or even death.
Cheng Chumo said in disbelief, "How can there be poison in the liquor? Don't lie to me. Hurry up and let me taste it. Don't be so stingy!"
Li Zexuan was too lazy to pay attention to this guy who didn't care about his life. He saw that more than two catties of the first liquor had flowed out, so he replaced it with an empty jar. He took the jar with the first liquor and prepared to pour it out.
Cheng Chumo saw through his intention and was anxious. If it wasn't for the fact that he couldn't beat Li Zexuan, he would have definitely snatched it.
Li Zexuan poured the first liquor in the courtyard. Cheng Chumo stood there reluctantly and sniffed the remaining liquor aroma in the air. He muttered with a look of pity, "Wastrel, wastrel!"
Li Zexuan ignored him and turned back to the room.
Two hours later, Li Zexuan came out with a jar of high alcohol concentration and placed 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 and pushed a glass of red wine over. She said, "Young Master, after many attempts, I found that the wine with this combination is easier to drink. Try it!"
Li Zexuan looked at the wine and hesitated. Han Yuxi smiled and said, "Young Master, don't worry. This wine won't get you drunk."
Li Zexuan then picked up the wine glass and took a sip. There was the sourness and sweetness of the mountain fruit in his mouth. After tasting it carefully, there was a faint wine fragrance, mellow and sweet. Li Zexuan nodded with satisfaction. Han Yuxi was indeed a genius in the field of winemaking. He only gave her a list of ingredients, but she actually figured out the ratio of various ingredients by herself. She was really amazing.
"Well, not bad, not bad. Yuxi, you are really amazing. Just mix according to this ratio!"
When Han Yuxi heard Li Zexuan's praise, she immediately felt that her hard work was worth it. She quickly agreed in a low voice and continued to mix the wine.
At this time, Cheng Chumo walked in and looked at Li Zexuan bitterly. Then he suddenly caught a glimpse of the cocktail that Han Yuxi had made. He immediately became spirited and shouted,
"Miss Han, is this the new wine you made? Quickly let me, a wine taster, taste it for you! "
Han Yuxi couldn't help but laugh. Li Zexuan couldn't do anything about this thick-skinned person. Cheng Chumo poured himself a glass of cocktail, then held it in his hand and praised,
"Well, just by looking at the appearance, I can tell that it's not bad. Miss Han, Xiaoxuan is really lucky to be able to find you."
These words were a little ambiguous. Han Yuxi's pretty face blushed. Li Zexuan glared at him and said angrily, "Hurry up and drink. Even good wine can't stop your mouth!"
Cheng Chumo laughed, picked up the wine, took a sip, smacked his lips, and then drank it all in one gulp. Cheng Chumo sighed and said,
"Miss Han, the taste of your wine is very novel. I have never drunk such wine before. Well, anyway, it's very delicious. But it's a little boring. It can't be compared to the wine that Xiaoxuan poured out just now. "
Han Yuxi smiled and said, "Young Master Cheng, this wine can also be matched with stronger wine. Please wait a moment."
When Li Zexuan saw that Han Yuxi had started to mix the wine again, he pulled Cheng Chumo out and said, "Chou Niu, come over and help me carry some things!"
"Well, don't you know how to ask the servants in your house to help you?"
"Have you ever heard that if you want to drink good wine, then hurry up and follow me."
Cheng Chumo could only follow unhappily. Li Zexuan dared to treat Lu Guogong's son as a servant.
Li Zexuan asked Cheng Chumo to come over to help him carry a bag of saltpeter. Although it wasn't heavy, it was free labor. It would be a waste if he didn't use it. He didn't want this guy to be bored and picky again.
Last night, Li Zexuan asked his father to help him purchase a few saltpeter mines. He didn't know how his father was doing.
Li Zexuan wanted to get some ice cubes. If he didn't add ice cubes to the strong cocktail, it would burn the stomach. With ice cubes, it would be more comfortable to drink.
