At night, the bright moon hangs high, the breeze comes slowly, and the whole courtyard is filled with the fragrance of grass and flowers.

At night, Su Chen was still industrious and busy, because he already felt the competitive pressure of the sugar gourd business, which would increase day by day, and the final sales and profits would shrink further.

Therefore, he had to consider that other products should be accelerated in research and development, released in advance, and introduced to the market.

At present, the soap technology has been mastered, and the soap has been basically formed, which is difficult to sell due to the constraints of the sales channel; He didn't know the place well, and it was a problem to find a large number of buyers.

The best plan is to find a reliable tycoon or strong family as a business partner, and take half of the shares by yourself; His partner will contribute manpower, materials, and be responsible for marketing and sales, which is the most trouble-free way, and he doesn't have to worry about it, just sit back and wait for the money to be collected.

However, if you don't have a trustworthy partner, this kind of thinking seems naïve, just find a businessman, it is likely that as soon as it is revealed, people will turn their faces and deny it when they get the secret recipe, and even kill people.

Eliminate the method of finding partners, and you can only produce and sell them yourself.

The worst plan is to set up a stall to buy, but this thing is a huge profit, and it is a new thing, which can easily attract the attention of wealthy families, businessmen, and officials from all sides.

At present, a relatively safe way is for Su Chen to take a few dozen yuan, dress up in disguise, and then go to a restaurant or a green building to sell it quietly, and then take the money to flash people and make a fortune after selling it.

"Hey, it's really troublesome, in ancient times, in addition to having no status in business, it is difficult to guarantee even the safety of life, unless you have strong assets, have a family to protect the home, and have a yamen relationship, you can live a profitable and stable life!" Su Chen sighed lightly, there is no better way for the time being.

This doesn't work, that doesn't work, feudal society is harmful!

Yang Ling'er walked over and asked, "Brother Su Chen, what are you doing?" ”

"Try making wine!"

"Winemaking?" Su Chen was speechless.

Su Chen nodded: "Yes, most of the wine on the market now is rice wine and rice wine, the alcohol content is too low, many heroes have a large amount of wine, and they should not be addicted. ”

Ancient liquor is mainly made of rice, millet rice, corn and other grains as the main raw materials, so it can also be called "rice wine", the degree is only a dozen degrees, and because the filtration technology is not mature in ancient times, the wine produced after filtration, it also contains a lot of fine rice residue, it presents a turbid state, and it is called "turbid wine" at that time. Therefore, in Du Fu's "Ascending", there is a verse of "Hardship, bitterness, hatred, frost and sideburns, pouring down a new turbid wine glass"!

In addition to this kind of "turbid liquor", there was also a kind of clear sake that appeared in the Tang and Song dynasties, which was often matured in winter and summer, and turned into a clear liquor after precipitation and fermentation, with a degree similar to that of turbid liquor, but with a sweeter taste, which was basically exclusive to the royal aristocracy. As depicted in Li Bai's poem: "The golden bottle of sake is ten thousand, and the jade plate is shy and ten thousand dollars." ”

In the last years of the Song Dynasty, after the nomads introduced distillation technology to the Central Plains from the north, the alcohol content in China increased from then on. By the time of the Ming Dynasty, the heroes did not dare to drink in large bowls, but began to drink in small sips.

If Wu Song lived in the Ming Dynasty, he would never be able to drink eighteen bowls of liquor, and then he would fight the tiger.

"Brother Su Chen, do you know how to make wine?" Yang Ling'er was suspicious, because Su Chen was an idle, lazy boy in the past, and he had never seen him learn any wine-making methods!

"This ...... A little bit of understanding requires trial and error! ”

According to the high school physics knowledge in his mind, Su Chen learned that in order to increase the degree of wine, it needs distillation, and the principle of this distillation technology is actually very simple, that is, the temperature required for alcohol to become gas is lower than that of water to become gas.

Because the vaporization point of alcohol is 78.3 °C, vaporized alcohol can be obtained by reaching and maintaining this temperature, and if the vaporized alcohol is then fed into the pipeline for cooling, it is liquid alcohol.

However, the process from rice raw materials to sake brewing is relatively complicated, and the complete process needs to go through repeated fermentation, which requires many tools from the brewery and more than half a year of brewing time.

Therefore, Su Chen did not plan to start from scratch for the time being, but used the rice wine he bought, reprocessed it, and used the distillation method to purify the exact concentration.

In the middle of the night, Su Chen was in the small courtyard, according to the method of making alcohol, heating the rice wine he bought with fire to a higher temperature, but he couldn't control it not to reach the boiling point of water, covered it with an iron pipe, and led the vaporized alcohol to the utensils next to it to cool, a little condensed, and liquid alcohol gradually appeared.

After many tests, it has been purified to a high degree of wine, but only three catties of rice wine produces a small half a catty of high-purity wine, which makes the cost of this wine also high.

Su Chen was not satisfied, continued to distill, repeated many times, and finally got about two taels of high-concentration alcohol, which can be used for disinfection and sterilization in the future, and then there are bumps and bumps of skin trauma, so you don't have to worry about bacterial infection. Otherwise, in this era of no anti-inflammatory drugs, it is very likely that a small wound will be infected, and if you are unlucky, you may die.

"Ling'er, bring some cotton balls!"

"Okay!" Yang Ling'er went into the room and fetched some cotton.

Su Chen took it in his hand, rubbed it into a small ball, dipped it in alcohol, took off his coat again, and wiped the bruises and broken skin on his body to disinfect and sterilize.

"Brother Su Chen, what is this doing?"

"Disinfection!" Su Chen just wanted to give it a try, and he had a bit of a professional reflex.

Yang Ling'er asked again: "Aren't we going to make sugar gourds tonight?" ”

She was a little strange, Su Chen had been tinkering with wine tonight, but she didn't make sugar gourds, wouldn't she sell them tomorrow?

Su Chen explained: "There are many imitators on the street today, and they are all selling sugar gourds, what Zhang Ji, Wang Ji, Cui Ji, Li Ji, many streets and alleys have appeared one after another, this business is no longer good, we use it to make a living, but it is difficult to make a lot of money and pay off huge debts, so we need to find another way." ”

"I see!" Yang Ling'er frowned, and a worried look hung on her pretty face.

Su Chen got up, stretched out his hand to stroke her hair and said, "Don't worry, my brother is already thinking of other ways, I won't go out to sell sugar gourds tomorrow, accompany me to the mountain to pick a kind of Panax notoginseng herb, and mix high-grade gold sore medicine, which can not only speed up the recovery of my injuries, but also increase safety by carrying it with me in the future, by the way, relax for a day, take a walk outside the city, and consider the next step to make money!" ”

After listening to this, Yang Ling'er didn't fully understand, but she still chose to trust him completely, leaned her head into his arms, and said softly: "Listen to Brother Su Chen!" ”
