"Soft, soft, fragrant, and glutinous. This crop called sweet potato is really delicious."

Qingfeng Yaxing Lao Ding is a well-informed person. After eating a bite of roasted sweet potatoes, he couldn't help but admire the fresh food.

Even Cao Yan and others who had just despised pork at the dinner table were eating sweet potatoes happily.

Xi Yunfei looked at Lao Ding, and saw the old man's thoughtful expression, and asked curiously: "What does Mr. Ding think of this sweet potato?"

When everyone heard this, they looked at Lao Ding, wanting to hear what this business senior would say, even Li Jing and Cheng Yaojin were no exception.

Old Man Ding didn't expect that he was just frowning slightly and was seen by Xi Yunfei. He thought to himself that the next wave pushed the front wave and hurriedly bowed: "My husband is joking, but I am just feeling it. If such high-yield crops appeared when I was young, many people might not starve to death. Haha, let Mr. laugh."

Everyone looked at each other when they heard this. Although Mr. Ding's words were a bit compassionate, they were a fact. Except for some people from aristocratic families who had been passed down for several generations, basically the previous generations were middle-aged and lower-middle-low peasants, just like He Sheng, who also lived a hard life.

Li Jing is a typical example. He was born in a turbulent family and rose up all the way. When he was young, he had no clothes to cover his body and could not fill his stomach.

However, Cheng Yaojin has a good background and has never experienced the feeling of being hungry.

Not to mention Xi Yunfei, she was an orphan in her previous life, so it was normal to be hungry.

After hearing Lao Ding's feelings, Li Jing also sighed: "Hanoi has been rich in sorghum rice since ancient times, but no matter how well it is taken care of, it is only more than 600 kilograms per acre. Compared with this sweet potato with a yield of 10,000 kilograms acre, it is a big witch."

"No," Old Ding nodded respectfully at Li Jing, and then said: "If this sweet potato can really achieve the miracle of yielding tens of thousands of kilograms per mu, only a thousand acres of fertile land can protect millions of people in the Dongcheng City of Shuofang without worries about food and drink."

"Haha, it's just a thousand acres of fertile land. Who here doesn't have a thousand acres of land? Not to mention others, even Lao He's family has more than 30,000 acres of land alone, right, Lao He."

He Sheng glanced at the person who spoke. The man was named Zhou Feng, and he also owned a restaurant, but he only sold alcohol, unlike his own restaurant that mainly deals in food.

Zhou Feng was also a local landlord in Shuofang. The wine he sold was brewed by his own home. His ancestral winemaking skills were the best in Shuofang, and he was the capital on which he survived.

He Sheng nodded to him without any objection, because the people here knew his wealth, but he still teased: "What Mr. Zhou said, your land in your house is much better than my house. Although the area is not large, it is all intensively cultivated sorghum land. One acre of land is more than three acres of my house."

"Hehe." Zhou Feng bowed and smiled, stopping his words.

Seeing these two opponents teasing each other, Xi Yunfei felt funny and hurriedly reached out and pressed him down, asking Zhou Feng: "Mr. Zhou, I heard that you are the best winemaking technique. I want to ask you a small question. I wonder if it is inconvenient."

Zhou Feng didn't expect Xi Yunfei would take the initiative to talk to him, so he nodded and said, "My husband, please tell me, Zhou must know everything."

Everyone looked at Xi Yunfei, wanting to see what he would ask.

Xi Yunfei smiled and said, "It's not a problem. I just want to ask Mr. Zhou, how many kilograms of wine can be produced per acre of sorghum."

"This?" Zhou Feng was a little confused and said that it was not a difficult problem. This question directly pointed to his core secrets.

Seeing that Zhou Feng's face was wrong and he was reluctant to say something a few times, He Sheng felt relieved, but he was a little overwhelmed with this question because his family also made wine. After thinking about it, he said, "I can answer this question of Lang Jun. Under normal circumstances, it would be good to produce four taels of wine per pound of sorghum."

Everyone nodded and agreed with this. They were all landlords. They could make wine if they had some surplus grain at home. They basically had 10 or 4 kilograms of sorghum, and about 10 kilograms of wine.

However, some people obviously had different opinions. Old Ding looked at Zhou Feng and said with a smile: "We brewed wine for 10 out of 4, but Zhou Yuanwai probably won't stop. I remember that I had drunk wine with Ling Gaotang once, and at that time, the proportion of wine production in Yingchunlou was already 5 out of 10 out of 10 out of 10."

Zhou Feng was stunned when he heard this. Unexpectedly, Old Ding would reveal his shortcomings. He glanced at Xi Yunfei, who was so frivolous, gritted his teeth and said, "I'm going to hide it from you, my secret recipe for brewing wine has been improved by several generations. Now, ten kilograms of sorghum produces six kilograms of wine, which is the normal ratio."

"Wow, six out of ten!" He Sheng didn't expect the proportion to be so high. No wonder the wine in Yingchunlou is always cheaper than his own.

Xi Yunfei just nodded when he heard this. The wine brewing in later generations was about this proportion, but the sorghum liquor in later generations was all high wines of fifty or sixty degrees, but this era did not meet this standard.

If the wine sold in Yingchunlou is only about twenty degrees, Xi Yunfei is sure to add water to thirty kilograms of high-altitude wine to thirty kilograms of sorghum. In this way, the yield is a positive number of one to three, which is huge profit.

Everyone's amazing eyes made Zhou Feng quite satisfied. After all, this era has a skill that is the foundation of life.

However, Xi Yunfei's next words shocked everyone again.

"In fact, sweet potatoes can also make wine, and the yield is not low. Although the wine production rate is not as high as sorghum, it can also have 30% or 40% of the base."

Sweet potato wine, also known as sweet potato wine, is a kind of homemade wine inherited from the public. It was originally a method of making wine invented because farmers were poor and wanted to drink. In later generations, many farmhouses still use old-fashioned tools passed down by the older generation to make sweet potato wine.

Moreover, sweet potato wine is easy to brew. You only need to boil the sweet potato and water and not too much water. After cooling to 30 to 40 degrees Celsius, use your hands to crush the blocky sweet potato until the water and sweet potato are completely mixed into a paste. Put it in a special wine koji and stir evenly and put it in a jar for fermentation.

In the cold winter, the fermentation tank should be wrapped with insulation materials such as quilts and straw. You can only steam the wine after fermentation for 10 to 15 days.

In addition, sweet potato wine has the effects of strengthening the body, eliminating wind and colds, and curing colds. Many older generations like to drink half a cup to warm their bodies in winter, and the effect is extremely significant.

"Wait." He Sheng's thoughts became lively when he heard that sweet potatoes could make wine. He calculated his fingers and said in surprise: "If a mu of land can really produce tens of thousands of kilograms of sweet potatoes, then even if the wine rate is only 30%, it is also 3,000 kilograms of wine."

"Three thousand kilograms!" Everyone was blushing when they heard this data. Zhou Feng was stunned and murmured: "My family only produces up to three thousand kilograms of wine for ten acres of sorghum. Can this sweet potato be just one acre of?"

Li Jing and Cheng Yaojin also looked at each other, with brilliant colors in their eyes. Wine is a necessity in this era.

Old Ding glanced at Cao Yan, and the latter was also upset at this time. If the plate of lychee meat had just been eaten, I was afraid it would be

Everyone looked at Xi Yunfei with expectations.
