Tobacco and alcohol belong to the profiteering industry, otherwise the state would not have monopolized the operation in modern times. However, at this time in the Tang Dynasty, the government did not seem to have discovered the value contained in this. The only industry that is monopolized by the government is salt and iron.

The salt and iron industry is now difficult to meddle in without a strong background, and cigarettes are not very popular in this era. There is only wine, and the Tang Dynasty has been peaceful for a long time, and it is a prosperous scene. Especially in Chang'an, drinking is popular. Literati flocked to it. So the wine industry is very profitable.

During the Tang Dynasty, the beverage wine of ancient China was mainly rice wine and wine. It is generally a folk creation. Rice (glutinous rice or japonica rice) or yellow rice raw materials are steamed, cooled, added koji, soaked in rice water, or added yeast and stirred, saccharified and fermented in the tank, pressed after the fermentation is completed, and the liquid squeezed out is rice wine. Rice wine is most famous for Shaoxing wine, with "Champion Red", "Jiafan Wine", and "Shaoxing Rice Wine "Daughter Red".

Rice wine is made of rice and millet rice, and the general alcohol content is 14%-20%, which is a low-degree brewed liquor. As for wine, it is imported wine. However, by the middle of the Western Han Dynasty, farmers in the Central Plains had learned that grapes could be used to make wine, and introduced Eurasian grapes to the Central Plains. At the same time as they introduced grapes, they also recruited winemakers, and since the Western Han Dynasty, China has had Western wine people. However, wine was only consumed among the nobility, and was not available to the common people.

At this time, it seems that the highly liquor, distilled spirits had not yet been invented. After Yibo came here, he also went to various restaurants to see, all of them are some low-alcohol liquors, and people have not yet mastered the brewing method of liquor. The wine that he pretended to be crazy and sold stupid heroes to save the United States was also very tasteless, how could there be spirits, this is the reason why Yibo did everything possible to win the restaurant of Xiaoyanjia. Because in his previous life, he was addicted to alcohol, so he also has some understanding of winemaking.

On the way back, Xiaoyan pursed her lips slightly, and when she saw Yi Bo's thoughtful look, she couldn't help but ask the question in her heart: "Young master, you don't really want to open a restaurant, do you......" Hmm! Yi Bo nodded, and when he saw that Xiaoyan looked like he wanted to speak and stopped, he hurriedly continued: "Don't persuade me, the little girl's family, I don't understand this...... "It's just ...... My father's alcohol is sold at such a low price, and no one comes to drink it, how can this restaurant make money......' Xiaoyan asked.

"The problem lies in the fact that the wine is sold too cheaply, and I heard you say that your home-brewed wine is not worse than others, or even better than others...... right?" Well, my father is really good at brewing, and there seem to be some ancestral skills in the middle, but I don't know the specifics of whether the male is passed on to the female or not......" Xiaoyan nodded heavily. "Let's put it this way, if there were two bottles of wine and you couldn't see the difference, one with a high price and the other with a low price, which bottle would you choose......"

"Of course it's a low price...... "Xiaoyan didn't think about it." This is the habitual thinking of ordinary people, and it is also the thinking of ordinary people, but if you think about it, if it were a young master and me, or someone like Song Yuan Zhang Qi to choose, which bottle would they choose...... "Yi Bo is kind and tempting.

Xiaoyan tilted his little head, thought for a while, and said, "I think Song Gongzi and they will definitely choose the expensive one, young master, it will also be ...... Now, not necessarily. Yi Bo smiled, when did he become so frugal, and then said: "That's it, then do you say that the common people are rich, or are we young masters rich......"

"Of course, the young masters and sons are rich, but my young master has no money......" Xiaoyan smiled. Begging for a beating, young master, I don't have any money, how can I help your family pay back the money^" Yi Bo felt that the girl Xiaoyan was deliberately doing it against herself, and she felt like she was being teased by the little girl. "Hmm...... The young master is so majestic, you don't know how the money boss temporarily changed his hexagram at that time, it's so funny, and the one named Wu Li, who is so shameless, and still thinking about Shuangyue. As soon as Xiaoyan became lively, he talked a lot. However, this seems to deviate from the original topic.

Yi Bo shook his head, he was really asking for trouble talking about economics with this innocent child. Xiaoyan said to herself: "Sister Shuangyue told me, if you want to marry someone in the future, you will marry someone like the young master, by the way, young master, why are you patting Shuangyue's head......" "That's to see her little girl cute...... That's why it was a whim. Yi Bo replied as a matter of course. Is it ......" Xiaoyan obviously didn't believe it, and then asked in surprise, "Shuangyue is not small, does the young master want Shuangyue to serve you together......" "Hmm......" Yi Bo was sweating profusely.

In the Tang Dynasty, it was easy to say about distilled liquor, but it was not easy to operate in practice. A few days later, Yibo came to the restaurant with a small cigarette. "What Wei Gongzi said, the old man is really unheard of, if the wine is burned with fire, won't it be steamed dry, and the smell of wine will disperse, then all that is left is a basin of water." Xu Dashan looked puzzled. Distilled spirits actually use the difference between the boiling point of alcohol (78.5°C) and water (100°C) to heat the original fermentation broth to between the boiling points, and the alcohol components and aroma substances can be evaporated and collected from it. But not to mention the boiling point now, just one degree Celsius is enough to explain it by yourself, and it is too difficult for you to carry out popular science education at this time.

There was no way, preaching was already meaningless, practice made true knowledge, and under Yi Bo's hurried explanation, in a specially opened room in the backyard of the restaurant, the original still was finally made.

Xu Dashan still didn't believe it, and quietly pulled Xiaoyan and asked: "How could your young master do such a thing, isn't he messing around......" Xiaoyan has never heard Yi Bo mention this still, and he is also a little hesitant: "The young master has changed a lot recently, let's see how he gets it first...... Although it is a little worse, but there is a possibility of implementation, and then, in the surprised eyes of Xu Dashan's family, Yi Bo steamed a jar of rice wine alive. Yi Bo wiped the beads of sweat from his forehead, which took several hours, and due to the simplicity of the still and his own unfamiliarity, the effect was not very good. There are a lot of volatilization, and the purity is not enough.

However, the small bowl of wine, which was like clear water, had just come out of the oven, and it was full of strong aroma of wine, and the fragrance was overflowing, and it felt like it had penetrated into the bridge of his nose. "Good wine!" Xu Dashan couldn't help but praise it, he had been immersed in winemaking for many years, and naturally knew that this was a rare wine when he smelled it. And this wine is as clear as water, better than the yellow and clear rice wine, the appearance is much better, Yi Bo couldn't help but taste it, the entrance is sweet, although it is not as good as the liquor of later generations, but it is much better than the low-alcohol wine at this time.

Then he distributed the bowl of wine, and though each man received only a small glass, everyone carefully tasted it as if they were holding a treasure. However, Xu Yong drank it all and shouted: "Happy, I have never drunk such a strong wine......" Xu Dashan finished drinking, his face was full of red light, and he looked like Guan Gong: "I didn't expect this turbid wine to go through such a ...... Well, it's called distillation, and it's going to happen like this. Xu Zhi was also happy: "It's better than our own wine, it's just her simple dress, not like her usual travel, so she asked."

"How can I go to this gathering of you big men, but if you go, I will be wronged and pretend to be a little girl to take a look......" Yang Qing'er smiled. This banquet is a good opportunity, the banquet in this lion building is indispensable for wine, An Qingxu claims to have a wide range of contacts and many friends, and should invite a lot of people to go, so this is simply a gathering place for Chang'an. Anyway, now I don't know how to sell liquor, so it's better to try my luck in the past. "Of course you have to go, this is not a Hongmen banquet, if you don't go, then it is really a long time to destroy your own prestige, but it is not good to be a girl, absolutely not, otherwise ......it will be debunked at a glance" Yi Bo deliberately sold a pass.

"Why?" Yang Qing'er really looked curious. "Because how can there be such a handsome girl, if this is seen by the young master of any family, then it will be repaid, and I will be in big trouble......" Yi Bo looked bitter. Hehe, I didn't find out, when did San Lang's mouth become so sweet, then sister, I really want to go over, lest you be stupid again, competitive and competitive, and eat An Qingxu's secret loss......" Yang Qing'er smiled, obviously very happy.

"Will I suffer?" Yibo was surprised. "Don't be strong, go this time, don't say anything big, if you really want to get angry or something, come to Japan for a long time, think about it in the long run......" Yang Qing'er persuaded.
