Chapter 68: Fermentation
Torrential rain has been busy lately.
Professor Li, who has made the most achievements in beer in the J major fermentation project, ordered the class to be divided into groups for beer brewing, and this time Rush and Yu Qianyue were assigned to the same group, and everyone decided to brew lager after discussion.
So everyone has to take samples for a week in a row to do index monitoring, what diacetyl, alcohol, cell number, can't be wrong at all.
When it comes to sake brewing, the more you know about it, the more you like it.
As a first-class light industry university, J University is even more unique in its research in winemaking. This is also the reason why she chose "brewing engineering" when she first filled in the volunteer for the first time.
When he was in Jinxi Town, Wang Wei's family at the bottom of the slope was brewing sorghum wine, and there was also a winery in the town. Therefore, when the rain was very small, I liked to smell the smell of sake, and I was also very curious and interested in the process of turning grain into sake.
Now that she has this opportunity, why wouldn't she give it a try?
After the surgery, Torrential Rain did have concerns, but as the course progressed, he wanted to try to get to the end more and more.
On the day of the fermentation, Professor Li asked each group to send a sampling representative.
Everyone thought that it must be taken back by the sampling representative, and let the group members taste and express their feelings one by one.
Rushing rain took the initiative to ask Ying to be the sampling representative, and her original biochemical professional experiments were more done, and the sampling techniques would only be more professional, so everyone had no objections.
Who knows, Professor Lao Li actually changed his teaching habits in the past, and asked the sampling representative to taste the wine directly after taking it, and then said his thoughts on the spot and scored it.
The rain was stunned - in front of everyone's eyes, it is not good to make temporary substitutions, which will affect the impression score. Everyone knows that Professor Li is notoriously strict. I hate students pushing and blocking the most.
To judge the quality of sake, follow the steps of "one look, two smells, and three tastes". Torrential Rain only did the first two steps, so he tried to sum things up more clearly, so that even if he missed one step, he could get as many points as possible for the group.
As soon as the beer was taken out from the beaker, Torrential Rain looked at the watch chronograph, then shook it slightly, and when the foam was hung in the cup, he said, "The three of us made the lower fermented Lage."
, pasteurized yeast, wheat raw materials accounted for 40.7%. Yellow beer, light in color, delicate and heavy in foam more than two fingers wide, no turbidity, good transparency. No floating debris, high stability; In addition to the wheat aroma, there is also a nutty aroma......"
She paused, looked at her watch, and added, "As far as I can speak, it's been a minute and a half now, and the bubble has not disappeared more than 50% faster, so the foam durability of the lager beer brewed by our group is also passableβ"
"What else?" Professor Li looked at her with a smile.
Rushing Rain pursed her lips, "The last step is to taste the taste, and I need to invite a group member to complete it together." Please also teach your permission. β
As soon as these words came out, not only Professor Li was puzzled, but also the students below were also discussing.
"Is this a foul on you?" "Can you still find a temporary helper?"
Professor Li knocked, and the surroundings immediately fell silent, he looked at the torrential rain, and his voice was calm: "Please tell the reason, the reason is valid, and it will be approved." β
Rushing rain was silent for a moment, and then said, "I had a spleen removal operation during the winter vacation, and I can't drink alcohol. β
"Oh my God!" "What's going on?" "Then how do you repair the brewing project?"
"She wasn't in our class originally, I don't know why she didn't want to start school?"
"Knowing that there are tigers in the mountains, I prefer to go to the tiger mountains."
Yu Qianyue, who was standing in the crowd, couldn't help but breathe when he heard the words, and raised his eyes to look at the torrential rain at the front.
I saw her calm demeanor, with a faint smile on her face, standing there with a pampered and unfazed attitude. He couldn't help but be a little moved.
"The reason is valid." Professor Li said, without showing any unusual look on his face, stretched out his hand to make a "please" gesture towards the torrential rain, and asked, "Which group member would you like to invite to help you taste?" β
Rushing Rain's gaze swept over the team members one by one, to be honest, the best taste appreciation ability belongs to the diving jump, although he is not here.
She finally made up her mind, "Yu Qianyue." β
Yu Qianyue was stunned for a moment when he heard her name report, and then strode up. He took the beaker from Rushing Rain's hand, shook it slightly, and took some sips, "The killing power is strong, because it is a lager, so there is no ester fragrance, but the wheat fragrance is refreshing." He glanced at Rushing Rain, who nodded slightly, and then said, "The third group is finished." β
"Not bad." Professor Li made a brief comment and then added, "I mean, you're right. He said to the two of them, "Now you take another cup, and I'll taste it, whether it's worthy of the name." β
Rushing Rain immediately took another sample and handed it to Professor Li, and after looking at it and smelling it, he raised his head and drank all the beer in the beaker, "Lager is not very drinkable, I'm glad you took this into account." I'll give you a nine. β
In Professor Li's dictionary, eight is already very high, and usually everyone hovers around seven o'clock. The third group where Torrential Rain was located couldn't help but jump up with joy, and Torrential Rain was also very happy, but her body didn't allow her to be sad and happy, so she just smiled from the bottom of her heart. As soon as she raised her head, Yu Qianyue's palm stood in front of her eyes, she was slightly stunned, and then slapped him with a smile.
After all the groups were judged one after another, the score of the group in Torrential Rain was still the highest. After the class ended, Professor Li said, "Jin Qiyu, you can stay for a while." β
Rushing Rain vaguely guessed what he was going to say to him, and stayed in response.
"I heard, you're majoring in a double major?" Professor Li asked.
"Well, I'm going to officially change to this major in my sophomore year." Torrential rain said.
"If you want to change majors, you have to be among the best in both majors."
Professor Li's words did not cause her to retreat, she smiled lightly: "I have this psychological preparation, I will work hard." β
"It's like today in itself, it's a group effort, so you need someone else to help you work on the project, and that's nothing." Professor Li said, "But you can't always rely on other people's help in the future, right? β
Torrential Rain knew that this was dissuading her.
"Does a winemaker have to know how to drink?" She asked, looking up. "But I've heard that a lot of winemakers don't drink themselves, they just need to know how to drink. And isn't it teamwork in the future? β
"You're saying 'drinkers don't be greedy for cups.'" "But at the very least, you have to know how to taste wine." After all, the wine is finally brewed for people to drink, and only two steps of 'looking' and 'smelling' are definitely not enough. β
"Those who are all over Luo Qi are not silkworm breeders." Rushing rain suddenly said such a poem, Professor Li was stunned, "What do you mean?" β
"Those who raise silkworms don't have to wear silk and satin on their bodies to know that the texture is good." She said.
"You're a sophistry." Professor Li said with a smile, maybe he also thought that the girl in front of him who looked delicate but had a strong temperament was quite interesting, so he said a few more words, "Do you know who invented wine?" β
Rushing Rain was stunned for a moment, "Are you talking about liquor or beer?" β
"Tell me about it."
"Beer was invented by the Sumerians. There is a record of the "Blue Monument" in the Louvre Museum in Paris, which was originally used to worship the goddess of farming; As for liquor, the saying in "The Eight Kinds of Shiben" is: "Yi Di starts, wine mash, becomes five flavors, and Shaokang makes straw wine." 'Yi Di and Shao Kang are both from the Xia Dynasty. She paused, "Of course, there is also a more common theory that baijiu was invented by Du Kang, who has become synonymous with 'liquor' in many ancient poems." β
After listening to her finish in an orderly manner, Professor Li couldn't help but say, "Your Chinese studies are quite good. β
Torrential Rain blinked in confusion.
"But...... What I want to tell you is that wine is not clothing, and clothes can be known without wearing them, because you can judge the quality of its fabric just by touching it, and it is no different from the experience of wearing it on your body. Wine, how can you know if it's good or bad if you don't drink it? It's like a chef, who has no sense of taste, and no matter how beautiful the things he makes, can he be called the god of food? β
"You...... You're trying to dissuade me, aren't you? Rushing Rain lowered his head, "But I really like the profession of winemaking." And......," the corners of her mouth twitched, "and it's not like I can't drink at all." It's just that it doesn't work now, but if you recover well in the future, it's no problem to drink a little bit like a wine tasting. β
Professor Li looked at her, sighed softly, and finally said from the bottom of his heart out of kindness: "Actually, you have a lot of talent for research, but I suggest that you don't change majors, otherwise you won't be able to complete every evaluation and assessment independently, if you really like it-" He muttered, "You still study as a minor major like now." If you master the fermentation technology well, you may not be able to engage in this profession in the future. There is a saying that you are right, in the future work, it is still teamwork. This is especially true when doing scientific research. β
"I see." Rushing Rain said sincerely, "Thank you, Professor Li." β
During the three-day holiday of "May Day", Torrential Rain did not return to S City, she called Chen Yuyao and said, and he also followed her and only said that he would go to see her on the last day.
The rosary was going to come to her on "Labor Day", and the tickets were booked a month in advance.
Originally, she didn't know about the "knife" of the Lantern Festival in the torrential rain. Until Torrential Rain was discharged from the hospital, she asked Torrential Rain if she could go to J University to find her on the Qingming Festival. Torrential Rain paused and replied, "I'm at home now." β
"Huh? What's going on? β
Rushing rain thought, anyway, the matter is over. Since she asked, I couldn't help but tell her. Save the rosary and always blame herself for refusing to tell her anything.
Even though she knew that she had been discharged from the hospital, Rosary still felt afraid, "Oh my God! She couldn't help asking, "Did you call the police?" Who did it? β
"Chen Yuyao asked me to leave this matter alone." Torrential rain said.
"That's right! Those people weren't here for you! Said the rosary.
Knowing that she didn't like Chen Yuyao, Rushing Yu smiled and didn't say anything more.
But she never dreamed that the person who also wore a black mask at that time was her old acquaintance.
