Liu Yong suddenly thought of Hua Tuo's later invention of "Ma Boiling San", which can produce general anesthesia effects and can be used for major surgeries. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Although Hua Tuo has not yet understood this formula, it should not be difficult if it only needs to produce a dull and drowsy effect.

Sure enough, Hua Tuo replied affirmatively: "Yes." ”

Liu Yong was ecstatic and asked, "Mr. Hua, if you put this medicine in wine, will the person who drinks it be able to smell or taste the medicine inside?" ”

Hua Tuo was stunned for a moment, and said strangely: "That's certain." Originally, this is medicine. When immersed in sake, it will not only have a special taste, but also a color. ”

Liu Yong's mood suddenly fell from the sky to the ground, and he was extremely depressed. Aren't there many descriptions of the magic of sweat medicine in "Water Margin" and martial arts novels? Colorless and tasteless, I don't feel anything when I drink it, but as long as I drink it, I won't wake up, are these all fake, are they literary and artistic creations? (Note: It is said that there is such a thing as a sweat medicine, and its main ingredient is mandala.) However, this drug is not available now, and Liu Yong does not know the formula)

Liu Yong was disheartened, bowed his hand to Hua Tuo, and said, "It's okay to interfere with Mr. Laohua, and I will think of another way in the future." He said goodbye to Dong Xi, Zhou Cang and others. Hua Tuo wanted to stay to treat Zhou Cang's injured brother, and seeing Liu Yong's lonely face, he whispered to Dong Yun: "Miss Xiaoyun, you go and take care of Liu Gongzi." Dong Yun agreed, and gently followed Liu Yong towards the post house.

Liu Yong thought as he walked, what else could he do to paralyze the enemy? Do you want to make those thieves slow to react and slow to move, but not to make them suspicious?

Dong Yun saw Liu Yong's frowns, sometimes shaking her head and sometimes sighing, she couldn't bear it, and persuaded: "Big brother, it's late at night, don't think about it anymore, go back and rest early, there are still many things to do tomorrow." ”

Liu Yong sighed and said in a low voice, "Yun'er." Your eldest brother is not good at this, and he can't sleep if he has something in his heart. ”

Dong Yun grinned and said, "Why don't Yun'er bring some wine to the eldest brother." The eldest brother fell asleep after a few drinks. Dong Yun was both comforting and making fun of Liu Yong's shallow drinking, and he would get drunk after a few drinks.

Liu Yong also smiled when he heard this: "Although your eldest brother's alcohol consumption is not very good, but the current alcohol content is low, I can still eat a few glasses." Suddenly, a thought popped up in his mind, Liu Yong slapped his forehead and said happily: "Yun'er, I have a way." Let's go back to the inn. ”

Liu Yong's idea was wine. The traditional method of sake brewing is made by steaming rice, mixing it with yeast koji when it cools to room temperature, and then fermenting it in a ceramic container. However, this brewing process does not produce high-grade liquor, because although yeast can ferment starch and other sugars to convert into alcohol, the concentration of alcohol can inhibit the growth of yeast and even cause its death. As a result, the alcohol concentration of the mash or liquor obtained by natural fermentation generally does not exceed 20%. This is the reason why ancient China only had low-alcohol liquor for a long time.

If you want to get a high concentration of liquor, you can only rely on distillation. This is because the boiling point of water is 100°C, while the boiling point of pure alcohol is only 80°C, so the more volatile alcohol (ethanol) can be distilled by heating, condensed, and collected to make a highly refined liquor with a concentration of 65-70%.

Although this principle is extremely simple, the ancients discovered and solved this problem much later. The documentary records are credible in the Yuan Dynasty, and it is also said that it is the Song Dynasty, but the earliest will not exceed the Tang Dynasty before the appearance of high-grade liquor. Shi Naixiang at the end of the Yuan Dynasty and the beginning of the Ming Dynasty confirmed the existence of high liquor from the side in the famous novel "Water Margin". When Wu Song was passing through Jingyanggang, there was a wine shop, holding a wine flag, and writing "three bowls are not post". If it is ordinary rice wine, how can ordinary people get drunk after drinking three bowls? Therefore, at this time, you can only drink high alcohol. Wu Song can drink eighteen bowls, which is estimated to be more than three catties of alcohol when converted into a person's current alcohol, which is really a lot.

After knowing the method, it is extremely easy to distill high-grade liquor, let alone Liu Yong, a modern person who has studied chemistry. Early in the morning of the second day, Liu Yong first asked Dong Yun to go to the market to purchase pottery urns, coarse bamboo, iron pots and other things, and he asked a blacksmith to put together an "N"-shaped iron pipe. When everything was in order, Liu Yong was in the backyard of the post station, leaving the others open, leaving only Dong Yun and Hua Tuo on the side to start steaming wine.

Liu Yong first put a large pot on the shelf, an iron frame in the pot, and a slightly smaller pottery urn on it. The top of the urn has an arched lid with an eye-sized egg drilled into it. Liu Yong inserted one end of the "N" shaped iron pipe into the pottery urn, and a long horizontal iron pipe with a slight slope in the middle was put into a cut half of the bamboo tube, which was filled with a constant flow of cold water as a condenser tube to cool the alcohol vapor. The joints of this set of utensils are filled with yellow mud to prevent air leakage, which is a simple water bath alcohol distiller. In this way, no matter how much the water in the cauldron boils, the temperature inside the urn will not exceed 100°C. The low-alcohol liquor in the pottery urn is heated to form alcohol vapor, which is sent along the closed iron pipe to the other end, and when it passes through the cold condenser tube, the alcohol vapor will condense, and then turn from gas to liquid, into water droplets, and slowly drip into the wine jar below along the inclined iron pipe. After such distillation, the concentration of the liquor can be greatly increased. Of course, this distillation method is very rudimentary, and when the alcohol evaporates, it takes away a part of the water vapor at the same time, so the resulting alcohol concentration does not exceed 75%. However, Liu Yong did not intend to refine pure alcohol, such a concentration is completely sufficient.

The hot alcohol vapor is constantly born from the inside of the pottery urn, and the iron pipe that passes through it will become hot for a while, and due to the conduction of heat, the cold water in the bamboo tube outside the iron pipe will soon be made into the same heat, and the steam will not condense in the future, but will be dispersed in the air and volatilized. Therefore, Dong Yun needs to constantly add ice water, one end to the other, to form a flowing water flow, and constantly take away the heat of the iron pipe, so that the alcohol vapor can be continuously cooled and more wine can be condensed.

Hua Tuo looked at the droplets of water dripping from the collection mouth in surprise and suspicion, he didn't understand what was the difference between the two after such a busy work. Liu Yong grinned and poured half of the lamp, and respectfully brought it to Hua Tuo's face, "Mr. Hua, what is the difference between your old products?" ”

Hua Tuo took it with suspicion, sniffed it first, and it was much stronger than the ordinary wine, and took a sip carefully, the entrance was really mellow, and exclaimed: "It's so spicy!" Chongru, why is that? ”

Liu Yong explained in detail, but Hua Tuo still didn't quite understand. But the process is not important, the result is important. When Dong Yun saw Hua Tuo's surprised expression, she knew that the effect of this wine was satisfactory, and she couldn't help admiring Liu Yong even more, and her heart couldn't help but be firmly tied to Liu Yong's body.

Liu Yong happily dedicated the newly made liquor to Yu Turn, waiting for Yu Turn's comments. Yu was surprised when he flipped through the product, and asked: "What kind of wine is Liu Gongzi brewing, why is it so mellow and intoxicating?" ”

"County Magistrate Yu, in fact, he used a special method to remove the water in the ordinary liquor, so that the taste of the liquor is much stronger." Liu Yong explained briefly, and said, "I heard that the county magistrate has a large number of bowls, but I don't know how many bowls the county magistrate can drink when he drinks this kind of wine?" ”

Yu rubbed his beard and said with a smile: "This wine is extraordinary, and the old man is afraid that he can only drink five bowls." ”

"The county magistrate is really massive." Liu Yong praised from the bottom of his heart, and said, "Thinking about it, the county magistrate will use this wine to honor that Yan Baihu the day after tomorrow?" ”

Yu Fu nodded and agreed, "Okay." If Yan Baihu drinks three bowls, he will definitely be delirious, and we can take advantage of the gap to do it. Catching a glimpse of the smug look on Liu Yong's face, Yu turned his face and said: "Liu Gongzi, this kind of wine is only used to deal with that strict thief, and it cannot be brewed again in the future." ”

Liu Yong was surprised for a while, and said curiously: "County magistrate, why is this?" ”

Yu shook his head and said, "How could Liu Gongzi not think of being so smart? The old man asked you, how much grain does it cost to brew a pound of high-grade liquor like yours? ”

Liu Yong thought for a moment and replied, "About three to four catties." ”

Yu sighed: "Three or four catties of grain can only make one catty of liquor." Fuyi has not much food, if the people who are good at wine and greedy for cups know this, how much food will they have to consume? Now that there are frequent wars in the north, and the number of displaced people fleeing here is accumulating more and more, Gongzi thinks about it, how many people can be relieved by those grains, and how much waste will be wasted if it is made into wine? The old man didn't let his son make this wine again, that's what he meant. Can the son understand the old man's hard work? ”

Liu Yong was stunned for a moment, and arched his hand: "The county magistrate Yu is worried about the country and the people, and Liu Yong admires it." However, the county magistrate, it is not necessary to make wine with rice, wheat and other satisfying grains, and it is okay to use other things, so the county magistrate does not need to worry. ”

Yu Fu was shocked: "Are there any other items that can also be used to make wine?" ”

"Yes." Liu Yong affirmed: "Cassava, rice bran, bran, and even straw can all be used to make wine. Seeing Yu Yu's skeptical expression, Liu Yong said eloquently: "In addition, the fermentation process can also be changed. Instead of using a clay urn, the raw materials are piled up in the pond and allowed to ferment naturally, resulting in a higher yield and a more mellow taste. Liu Yong's hometown has Xushui Cellar Pond, and there are world-famous cellars such as Wuliangye, Luzhou Laojiao, Shuijingfang, etc., which naturally know its function, so the whole process of brewing process from feeding, fermentation to distillation is revealed.

"There is a method that has to be mentioned in winemaking, which is called the slag continuation method." Liu further explains, "It is a mixture of sake lees, rice bran and raw materials, and then repeated fermentation and distillation. Its advantage is that various raw materials can be fermented many times, which improves the utilization rate of raw materials and saves costs. Moreover, after many fermentations, it is also conducive to the accumulation of flavoring and flavoring things, making the wine more mellow. ”

Yu Chuan was surprised and delighted: "Do Liu Gongzi know all these skills?" ”

Liu Yong nodded, and said solemnly: "Don't hide it from the county magistrate, there is a winery next to Liu Yong's former residence. ”

Yu Fu was overjoyed, stroked his beard and said with a smile: "Young Master Liu, the old man is really lucky to meet you." As soon as the bandits are eliminated, we will build a pond to make wine. The old man thinks that there are many rich families in Xiangyang and Jingzhou, so this wine will not worry about no market, which is the most important source of income for our county. The two looked at each other and smiled, full of hope for the future.
