Zhu Yunwen smiled and said, "It's definitely good wine, but I have a way to make it even better."

Zhu Yuanzhang immediately asked in confusion:

"Could it get any better? This is already the best wine we've ever drunk. Yun-hu, how can you make it even better?"

Zhu Yunwen smiled, then picked up the jar of wine and said to Zhu Yuanzhang:

"Grandpa, please have something to eat here. I'll go to the Imperial Kitchen and be right back."

Zhu Yuanzhang, unaware of Zhu Yongtong's intentions, nodded and did not stop him.

When Zhu Yunwen arrived at the imperial kitchen, he instructed a eunuch to start a fire. The eunuch poured the jar of wine into a pot, then took an iron lid, placed it on the pot, and added a ring of containers around the pot to collect the steam and liquid.

And so he made a very simple distillation apparatus.

The boiling point of alcohol is not high. Once it reaches a certain boiling point, which is about 70 degrees Celsius, the alcohol will boil.

Then the alcohol inside will evaporate into gas and rise, adhering to the lid of the pot.

If you add cold water to the outside of the pot lid, it will be cold. When the steam inside encounters the cold pot lid, it will quickly condense into water droplets and drip down.

When collected, it becomes pure distilled spirit.

After the wine undergoes this simple distillation process, the water in the wine remains in the pot, while the alcohol is extracted.

In this way, the alcohol concentration can reach about 75 degrees.

In fact, 75% alcohol is already considered medical alcohol, and drinking it would be very harmful to the body.

Therefore, Zhu Yunwen did not lower the boiling point, but instead increased the heat and added some water.

It's just that more water has been removed from the original liquor, increasing its purity, strength, and concentration.

After his processing, the grain liquor that was originally only about 20 degrees has now reached at least 40 or 50 degrees.

Zhu Yunwen could roughly guess this, because it was originally a bottle of wine, but now it was about a third less.

After packing the redistilled liquor, Zhu Yunwen took the liquor back to Shaoyang Palace.

Zhu Yuanzhang was gnawing on a pork chop, while the two little girls were also eating sweet and sour pork.

Zhu Yunwen smiled and stepped forward, poured a cup of his processed wine for Zhu Yuanzhang, and said:

"Grandpa, please taste the wine I've processed again."

Zhu Yuanzhang nodded: "Then we must have a good taste. But Yunhuo, you only poured me such a small cup. Isn't that a bit disrespectful to your imperial grandfather? Come and fill your imperial grandfather's cup."

Zhu Yunwen smiled and said:

"This wine is very strong. I'm afraid Grandpa Emperor won't be able to handle it if he drinks the whole cup straight away."

Zhu Yuanzhang immediately said, displeased:

"You can question everything about Grandpa, but you absolutely cannot question his drinking capacity. Do you know that from the very first day he embarked on his great undertaking, Grandpa has never yielded to anyone at the drinking table?"

Don't be fooled by how formidable those military generals are in battle; when it comes to a drinking party, no matter how tough they are, they'll turn into cowards in front of us.

Zhu Yunwen said, "It's not that I doubt my grandfather's alcohol tolerance, but this wine is indeed very strong after I've processed it. Even this small half cup, my grandfather has to take a small sip and can't drink it all at once."

Zhu Yuanzhang was quite stubborn; Zhu Yunwen said he was incompetent at everything except drinking.

He then said seriously, "Yunhu, fill Grandpa's cup, otherwise people will think that Grandpa can't afford to drink. Come on, fill it up quickly, one cup for each of you."

Zhu Yunwen had no choice but to fill Zhu Yuanzhang's cup.

That cup wasn't small either; if it were full, it would probably weigh about two ounces.

However, Zhu Yuanzhang didn't care at all, and downed the wine in his cup in one gulp.

The next moment, his eyes widened, and he opened his mouth to say:

"Oh my, this liquor is really strong. It burns all the way down to my throat. It's terrifying."

Zhu Yunwen smiled helplessly and said, "I told you so long ago, but you didn't believe me."

Zhu Yuanzhang smiled awkwardly and said, "I didn't expect the wine to suddenly become so strong. Yunhu, what did you do?"

Zhu Yuntong said, "Based on the liquor, I used the same method to purify it again and increased its alcohol content. The higher the alcohol content, the more fragrant the taste, and naturally, the better it tastes."

Zhu Yuanzhang hurriedly nodded and said, "Yes, it is indeed good wine. It seems that we will need you to help us refine it in the future."

Zhu Yunwen didn't say much, but Zhu Yuanzhang found the wine quite delicious, so he drank several cups in succession.

Seeing this, Zhu Yunwen couldn't help but remind him:

"Grandpa, this wine is very strong, with a high alcohol content. One cup is equivalent to two cups you used to drink. If you drink too much, you will get drunk very easily."

However, Zhu Yuanzhang, being a stubborn man, was clearly too confident and said to Zhu Yunwen:

"Don't worry, Yunhuo, your royal grandfather's alcohol tolerance is absolutely no problem. These few cups of wine won't make me drunk."

But as soon as he finished speaking, he rubbed his forehead and then mumbled sleepily:

"Alcohol is a good thing, hehehe..."

Zhu Yunwen was bewildered by his two inexplicable laughs, and at the same time, he had a bad feeling.

Sure enough, the next moment, Zhu Yuanzhang, drunk, hooked his arm around Zhu Yunwen's shoulder and said:

"My dear grandson, shall we give you the throne?"

Zhu Yunwen's face immediately darkened.

I was just trying to get you to drink less, how did you get drunk so quickly?
