Li Mansion, West Courtyard.

In the makeshift simple workshop, the iron egg is burning on the fire, and Li Zexuan is pouring liquor into the distillation pot, and paying attention to the temperature in the pot.

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

Tie Dan asked curiously.

Li Zexuan saw that he had time now, so he popularized scientific knowledge for his cheap apprentice.

"Just heating, of course, you can't get stronger wine, Iron Egg, have you ever boiled boiling water before?"

"Well, of course it did."

"Then have you noticed that after boiling water, if you continue to boil, there will be less and less water in the pot?"

"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. What Master has to do now is to steam out the water in the wine to make it more concentrated, you know? ”

Tie Dan nodded thoughtfully, and then wondered, "Then Master, will you steam out the alcohol together like this?" ”

Li Zexuan exclaimed: "Tie Dan, you asked this question well, this is the most critical part of distilled spirits, in fact, compared to water, alcohol is more volatile at a lower temperature."

Well, in other words, if we cook together, the alcohol will be steamed out first, and then we add a tube washed with cold water in the back, and the alcohol will be cold and turn into liquid, you know? ”

The boiling point of alcohol is around seventy-five degrees. The temperature must be lowered below 75 degrees to liquefy, and the evaporation rate at about 50 degrees is very fast, so at least the condensed alcohol is cooled to below 50 degrees in the condenser tube, and it is generally cooled to about 30 degrees before flowing out. Of course, there are also cooled at lower temperatures.

Tie Dan shook his head in confusion and said, "Master, you understand the iron eggs you said earlier, but later you said that those volatile alcohol entered the pipe and turned into liquid, and this iron egg didn't understand very well. ”

Li Zexuan patted his forehead, and had no choice but to explain to Tie Dan the junior high school physics knowledge of the vaporization of the solution when it meets heat and the liquefaction of steam when it meets cold, and Tie Dan then understood.

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

"Yes, Master!"

............

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

"Wow, it smells so good, Master, it's much more fragrant than what my dad usually drinks."

Tie Dan sniffed vigorously on the side and said excitedly.

Li Zexuan smiled slightly, undeniable.

"Xiao Xuan, what kind of wine are you, it's so fragrant?"

Cheng Chumo, who was outside the house, smelled the strong aroma of wine, where could he still bear it, and immediately rushed in, this thing didn't know how to write the word polite, and was about to come up and take away the wine jar under the condenser tube.

Li Zexuan hurriedly stopped:

"Stop, this freshly brewed wine is poisonous, you can't drink it!"

Although the freshly distilled head wine has a high alcohol concentration and smells very good, the head wine contains a large number of low boiling point substances such as aldehydes, esters and ketones, which can lead to blindness and death.

Cheng Chu said in disbelief: "How can the wine be poisonous, don't lie to me, you kid, bring it to me to taste, don't be so stingy!" ”

Li Zexuan was too lazy to pay attention to this rammer who wanted to drink and didn't want to die, he saw that the first wine flowing out was more than two catties, so he changed to an empty wine jar on top, and lifted the jar with the first wine out, ready to pour it out.

Cheng Chumo saw his intentions, and jumped in a hurry in the back, if he hadn't been able to beat Li Zexuan, he would definitely have robbed it.

Li Zexuan poured the first wine into the courtyard, and Cheng Chu stood in that place reluctantly, sniffing the residual aroma of wine in the air, and muttered with pity: "Loser, loser!" ”

Li Zexuan ignored him and turned back to the house.

An hour later, Li Zexuan came out with a jar of high-strength wine, put it on the table next to Han Yuxi, looked at Han Yuxi and asked, "Yuxi, how is it, have you figured out the ratio of each raw material?" ”

Han Yuxi nodded, pushed over a glass of red wine, and said, "Young Master, after I tried it many times, I found that the wine with this combination is easier to eat, you can taste it!" ”

Li Zexuan looked at the wine, a little hesitant, Han Yuxi smiled and said, "Young master, don't worry, this wine is not intoxicating." ”

Li Zexuan picked up the wine glass and took a sip, the entrance had the sweetness and sourness of mountain fruit, and after tasting it carefully, there was a faint aroma of wine, mellow and sweet, Li Zexuan nodded with satisfaction, Han Yuxi was really a genius in winemaking, she just gave her a list of raw materials, and she actually figured out the ratio of various raw materials by herself, which was really amazing.

"Well, not bad, you're really good, you're really good, just adjust it according to this ratio!"

When Han Yuxi heard Li Zexuan's praise, he immediately felt that his hard work was worth it, and hurriedly agreed in a low voice, and continued to mix wine.

At this time, Cheng Chumo walked in and glanced at Li Zexuan with resentment, and then he suddenly caught a glimpse of the cocktail prepared by Han Yuxi, and immediately came to his senses, and he shouted:

"Miss Han, is this your new wine? Hurry up and let me, the master sommelier, help you taste it! ”

Han Yuxi couldn't help but laugh, Li Zexuan couldn't help but be cheeky. Cheng Chumo poured himself a cocktail, and then held it in his hand and sighed:

"Well, just looking at this appearance is good, Miss Han, Xiao Xuan can find you, it's really shit luck."

These words were a little ambiguous, Han Yuxi's face flushed, Li Zexuan glared at him, and said angrily: "Drink it quickly, the wine can't stop your mouth!" ”

Cheng Chumo laughed, picked up the wine, took a sip, smashed it, smashed it, and then drank it all again, and saw Cheng Chumo sigh:

"Miss Han, the taste of your wine is very novel, I have never drunk such wine, well, it is very delicious anyway. It's just a little boring, it's not as good as the wine that Xiao Xuan poured out just now. ”

Han Yuxi smiled and said, "Cheng Gongzi, this wine can also be matched, you can wait a minute." ”

Li Zexuan saw that Han Yuxi had started to mix wine again, so he pulled Cheng out silently and said, "Ugly cow, come over and help me move something!" ”

"Well, you won't ask your subordinates to help you?"

"Eat people with a soft mouth, take people with short hands, have you heard of it, if you want to drink good wine, come with me quickly."

Cheng Chumo could only follow him in a huff, daring to treat Lu Guogong's son as a family envoy, and Li Zexuan was no one.

Li Zexuan asked Cheng Chumo to come over because he wanted him to help him carry a bag of saltpeter, although this thing is not heavy, but there is no need to use this free labor in vain, so as not to have this thing idle there again, pick and choose.

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 just wanted to get some ice cubes, strong cocktails, if you don't add ice cubes, it will be too stomach-burning to drink, and if you have ice cubes, it will be more refreshing to drink.
