Throwing the sale of two snacks, bowl chicken and skewered iron plate bird eggs, to Taipan Xiaoban and Angel, Xu Zheng's attention returned to the matter of brewing wine.

Of the types of sake brewed so far, the most troublesome in the whole fermentation process is beer. This thing is not like the fermentation of other wines, which is more troublesome in the early stage, and there are more hands and feet, but once it is sent to the fermentation process, you only need to pay attention to the fermentation temperature. The fermentation process of beer is divided into three steps: pre-fermentation, main fermentation and post-fermentation. Especially in the case that there is no native beer fermentation mother and only ferments with koji from Lao Banga, it is necessary to pay attention to the entire fermentation process.

The pre-fermentation takes from half a day to a day, during which Lao Bang and Barlow are waiting for the whole process and have been completed. During the period when Xu Zheng's bowl chicken and teppanyaki were on sale, the beer was fermented mainly. Lucina became a mouthpiece at this time, passing on the fermentation of beer to Xu Zheng the next day.

The wort obtained at the beginning was a total of 12 cylinders, after a day of pre-fermentation, the liquid surface began to appear white foam, and the volume of the wort had a significant tendency to increase, Xu Zheng divided it again to obtain 17 cylinders of wort after initial fermentation. Each of the 17 vats was not full, only about two-thirds of the volume, in order to prevent the wine from being lost due to fermentation. The 17-vat wort transitions from pre-fermentation to main fermentation, and the white foam on the liquid surface increases day by day, reaching the maximum amount of foam on the third day, and gradually declining after about 3 days, approaching the pre-fermentation to the appearance of just entering the main fermentation, and the whole main fermentation process is completed. At this time, Xu Zheng asked Carlo and others to help and take the wine vat to the courtyard to cool down. After another two days, I opened the vat and tasted the beer.

Obviously, the wine tasting task was best left to Old Banga and Barlow. You must know that Xu Zheng slept in a hospital bed for 147 years in his previous life, and he only relied on absorbing knowledge from the Internet, so he knew more about winemaking, and he was not good at wine tasting at all, so he didn't participate in the mix, but stood aside and watched Lao Banga and Barlow each take a cup and pour some out, and after drinking, they closed their eyes and made a fairy shape.

"How?" asked Xu Zheng. It is false to say that you are not nervous, and it is a qualitative leap from theory to practical operation. It is not easy to go from theory to brewing something practical. Xu Zheng is also worried about whether the beer will succeed.

Lao Bangjia tasted it for a long time before he said, "It already smells of wine." And the smell of malt, refreshing and delicious, it's a good thing!"

Barlow said: "There is a bitter taste of hops. But it's not that it's not delicious, but it feels good. This kind of bitterness is a little strangely bitter, as if it is not beautiful. It's really exciting to see what it will look like when it's fully fermented. ”

Hearing this, Xu Zheng was relieved, and it seemed to be a success. Xu Zheng said: "Strictly speaking, the wort that has undergone main fermentation is not considered beer, but can only be called fermentation broth. When you drink it at this time, you can feel the mellow and soft flavor and malty aroma, so it can also be called tender beer. And real beer is finished after post-fermentation, and I bet that the post-fermentation tender beer and the current tender beer are absolutely different things. You'll be amazed. ”

Lao Banga said: "How to carry out post-fermentation?"

Xu Zheng said: "What we have to do is to filter these tender beers with cotton cloth, remove all impurities and precipitation, then filter them with pumice stone, and finally bottle them, seal them, and live for 10 to 15 days, and the first batch of beer in the Aris continent will appear!" Where am I going to find those bottles now? Grandpa Banga, do you have any more?"

Barlow said, "I'll leave this to me." I have a lot of bottles there. How much is it going to be?"

Xu Zheng frowned, looked at the 17 wine tanks in the courtyard, and said, "I can't estimate it." Grandpa Barlow, how much do you want?"

Barlow broke a twig and leaned into the vat to test the depth of the wine, and after a while, said, "I estimate that a vat will cost about 60 bottles." How much is in the bottle? If it is not enough, more bottles will be needed. ”

Xu Zheng said: "It can be filled, just leave a little gap." Be sure to choose a sturdy bottle. ”

"Why?" asked Barlow.

Xu Zheng said: "Because this is a kind of foam wine, our method is also a home-made method, and the final fermentation is completed in the bottle, and the volume of the beer will swell in this process, and the bottle will not be strong enough, and it will burst." ”

Isn't foam in wine always considered inferior? But he also tried tender beer, and although it is still a semi-finished product, its unique flavor can already be roughly reflected, and such a wine cannot be inferior after drinking. Then why do you say that it is foam wine? Turning his head to look at Xu Zheng, seeing that the latter looked confident, Barlow could only suppress his curiosity, and he would try it later, and he hurriedly went out to collect bottles.

Seeing Barlow go out, Xu Zheng smiled at Old Banga and said, "Grandpa Banga, borrow your grandson." ”

Lao Bangjia saw a lot of novel skills here in Xu Zheng during this time, and he was very close to Xu Zheng in addition to being happy, and when he heard him say this, he joked to Xu Zheng: "What do you want to do? Use my grandson to make wine? A few days ago, I heard that you are going to use fatty pork, and my grandson is so thin that he is a bag of bones, and he can't help you much." Hahaha. ”

Xu Zheng was also happy and said, "How dare I." Grandpa Banga, your grandson brought me to brew like this, where can I find a grandson to compensate you?"

Old Banga smiled: "I won't have to pay me with you." With a grandson like you, he is more than a hundred times stronger than my grandson. He also said that he would pass on my wine-making skills to Xiao Bangjia, and with a grandson like you, I am afraid that when the time comes, I will only pass on my grandson to my grandfather, so how can I pass it on to you. ”

Xu Zheng felt a big chill in his heart, dead old man, take advantage of me...... One bite for a grandchild. However, Lao Banga's age didn't seem to be inappropriate for his grandfather, so Xu Zheng could only laugh dryly, let Lao Bangjia take advantage, and said, "Yes, yes." Grandpa Banga, you're right. Let's not say this will work, okay?"

Lao Bangjia was even happier when he saw Xu Zheng's deflated appearance. This stinky boy usually drags him very much, and it seems to be quite fun to take advantage of him. Seeing that he had a deflated mouth, old Banga stopped teasing him and said, "Tell me, what's the matter?" ”

Xu Zheng said: "I'm not familiar with the emperor, and the last time I asked a blacksmith to help make the iron plate of teppanyaki, I asked Angel to go." To be honest, the craftsmanship of the craftsmen is really not very good. Fortunately, the iron plate for making teppanyaki is not very demanding, so the process is almost nothing. But this time this thing can't be sloppy, so I want to ask little Banga to take me to a good blacksmith and make such a thing. ”

As he spoke, Xu Zheng picked up the branch that Barlow had used earlier and drew a sketch on the ground. This thing is a steamer, and the structure is more complicated, because the temperature must be strictly controlled, so it is a pot within a pot structure. The bottom is the part that is directly in contact with the fire for heating, and the middle can be filled with water, and then there is a pot in the water, the principle is to use water as the heating medium, not directly heated by the flame, which is convenient for controlling the temperature. At the same time, there are some seventy-seven-eighty-eight ideas, Xu Zheng used them all on it, and painted them for Lao Bangjia to see. While painting, Xu Zheng is still refining his concept, so he is still adding components to the original form.

At first, Lao Banga could still understand that it was roughly a pot, but after looking at it for a while, he was already dizzy, and hurriedly said: "Stop, stop, stop." Little Banga can't help with that. This thing is too complicated, I suggest that little Banga take you, and you two go to the sharp-bladed blacksmith shop in Uptown, and find the workers there to make it for you. Don't draw this thing for me, I'm dizzy. By the way, what the hell is this thing for?"

Xu Zheng then remembered that with the current wine-making process of the imperial capital, all that can be brewed is fruit wine, and grain winemaking has never appeared at all. This means that the raw material for sake brewing is obtained in two different ways. First, the fermented juice is processed before fermentation, such as citrus and other alcohols rich in fruit juice, and the fermentation broth is fermented directly after the fruit is juiced. The second is to press the source material after the fermentation is completed to obtain the liquor, and after completing the steps of filtration and precipitation, the finished liquor is obtained. Both of these methods lead to the same goal, and in the end, they can get the wine after being pressed. This also shows that with the current brewing technology of this otherworld, there is only pressed liquor, not distilled liquor!

Xu Zheng figured this out, and his heart couldn't help pounding. On the one hand, I lamented the backwardness of the winemaking technology here, and even the oldest hometown of wine, the wine processing of the Tang and Song dynasties in ancient China in the Milky Way, while at the same time, I also felt that this was a once-in-a-lifetime business opportunity.

For the imperial capital, where the process of pressing liquor is still very rough, if a new level of distilled liquor suddenly appears, what is this concept? Thinking of this, Xu Zheng's heart can't help but pound!

I only felt that my lips and tongue were dry, and Xu Zheng swallowed a mouthful of saliva hard before saying, "Grandpa Banga, this thing is also used to make wine." When I make it, I use it to process the wine, and I can't imagine how strong the wine will be. Now, tell me how I can get to Uptown and find that sharp-edged iron shop. ”

Lao Banga looked at Xu Zheng's appearance, and intuitively felt that this thing must be very important, so he couldn't help but get serious, took out a chip in his arms and handed it to Xu Zheng, and said, "If you want to go to Shangcheng District, you must have a first-class resident certificate in Shangcheng District." I have this thing, and I also have it in Xiao Bangga, and if you take mine, you can only show it to the guards guarding the city gate when the time comes, and you can freely enter and leave the upper city. After a pause, he said, "The owner of the sharp-bladed blacksmith shop is more annoying, so I will hand it over to Xiao Bangjia to deal with when the time comes." ”

Xu Zheng nodded, indicating that he remembered, took the chip from Lao Banga's hand, and then waited for Lao Bangjia to find someone to call Xiao Banga.
