Distillation is a thermodynamic separation process.
It takes advantage of the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling component and then condense it to separate the entire component.
It is a combination of two unit operations: evaporation and condensation.
To put it simply, the fermented wine is heated into wine steam, separated from the water, and finally cooled into wine!
This is a very effective way to improve the purity of wine.
Because the wine vapor separated by heating is high-concentration alcohol separated from ‘water’, after it is made into wine, it needs to be blended, and then it is the real liquor.
Generally speaking, the entire distillation process will be divided into three stages, mainly distinguished by the heating temperature.
The first stage is when the distillation temperature is below 78 degrees, and the separated wine is the so-called head.
The content of low-fraction fusel oil, low-grade fatty acid esters, aldehydes, etc. in the wine head is high, and it has a certain aroma, but the off-flavor is relatively strong, and it also causes certain damage to human vision. It is generally stored separately.
The second stage is when the distillation temperature is between 78 and 95 degrees. The separated wine is normal distilled wine, which is the commercial wine sold in the world where Jiang Fan lives.
The third stage is the distillation temperature of about 95 to 100 degrees. What comes out is the tail of the wine, which has a mixed and bitter taste. It is basically taken out separately and stored together with the head of the wine.
The process of distillation from start to finish is actually not that long in terms of time alone.
However, it is necessary to master the intensity of the heat. Different stages have completely different requirements for the heat. Jiang Fan specifically checked this online.
After all, it was my first time doing it, so I was a little nervous.
Jiang Fan couldn't help but take deep breaths while carefully sensing the changes in temperature.
There is no such thing as a thermometer in this world, so the only thing you can rely on to control the distillation temperature is your feeling!
Su Xiaonuan and others were waiting nearby.
Except for the guards who had to stay outside the workshop, everyone else entered the workshop and carefully watched every step of Jiang Fan's operation.
This is Jiang Fan's request.
After all, he couldn't always do the brewing thing himself. He had to let the trustworthy members of the Lin family learn how to do it, and then the Lin family would take charge of the brewing workshop.
As for outsiders, Jiang Fan has no intention of passing on this wine-making technique.
Even if this approach will limit the production of wine, since this is the first time that this high-quality liquor appears in the world, it must take the high-end route.
The price is bound to be very exaggerated, and it is absolutely impossible for ordinary people to afford it, except for dignitaries.
In this way, the problem of wine production is no longer an issue.
In less than half an hour, the entire distillation process was over.
The wine liquid separated by distillation was not directly sealed in the jar, so that the aroma of the wine permeated the entire workshop!
This aroma makes people feel as if they are in heaven, refreshing the heart and mind!
Even someone like Jiang Fan, who doesn't like wine at all, can't help but swallow his saliva when he smells it.
Not to mention the performance of Su Xiaonuan's group at this moment is even more unbearable!
After hesitating for a moment, Jiang Fan couldn't hold back his curiosity after storing the head and tail of the wine separately. He took a wine spoon, scooped out some new wine, about one or two ounces, and took a tentative sip.
Delicious!
It tastes really good!
Although Jiang Fan is not good at drinking, he was born in Beijiang Province after all, and he is naturally capable of drinking.
Growing up, he drank a lot of various kinds of liquor, ranging from Maotai Wuliangye to village chief Erguotou. Basically, no matter how many, he had at least tasted them.
But Jiang Fan is very sure that no matter which kind of liquor he has drunk in his world, it is not as delicious as the one he brewed at this moment!
It can even be said to be a world of difference!
The alcohol content is not low, almost 70 degrees, so it stands to reason that it should go through the blending process.
But now it is obviously still puree, but it is extremely soft in the mouth and does not feel the slightest bit spicy. The aroma is fragrant and the taste is extremely refreshing.
However, after swallowing it, the alcohol's intensity dissipated instantly, causing the whole body to feel a wave of heat.
The smell of alcohol hit his head, making Jiang Fan slightly dazed, but after all, it was just a sip, so he returned to normal in an instant.
Staring blankly at the remaining wine in the wine spoon, Jiang Fan found it difficult to understand.
The way I chose to make wine is actually extremely rough.
Basically it can be regarded as without any technical content.
Regardless of the brewing technology, the sophistication of the entire process, or even the extraction of the wine itself, there is nothing worthy of praise.
Not to mention comparing it with the hard-covered commercial wines in my own world, even compared with the self-brewed liquors in Beijiang Province, it is definitely not as good as it is.
After all, this is my first time making wine, and I have no experience before this.
But why...the wine produced is so excellent?!
Thinking about the unusually short fermentation time, Jiang Fan even discovered when he tasted the wine that had not been distilled just now that even such a short fermentation time was still long...
So...what key factors have I overlooked?
Seeing Jiang Fan fall into deep thought after taking a sip of the wine, Lin Wanqing on the side thought that Jiang Fan was shocked because of the poor taste of the wine.
He couldn't help but hurriedly said: "Brother Jiang Fan, it doesn't matter if the wine is not brewed well. It's just a try anyway. Besides, according to Xiao Nuan, even if the wine is not brewed well, it will still be much better than Heyang Daqu. You must do it
Don't take it personally."
"It's not brewed well? Who said it's not brewed well?"
Jiang Fan's thoughts were interrupted and he asked with a surprised look on his face.
"Ah? I think, brother Jiang Fan, you didn't seem satisfied after taking a sip, so I thought it might be a problem with the wine..."
Lin Wanqing said in a daze.
"I'm not dissatisfied. I'm so satisfied. I didn't expect that the brewed wine would be so delicious. Come on, let's all have a try."
Jiang Fan smiled and called the other Lin family members in the workshop to see if there was something wrong with his taste buds.
After a while, all the Lin family members in the workshop drank two ounces of wine each, and then they all drank it up in one gulp with great boldness, unlike Jiang Fan just now, who did so in a delicate way of "sipping".
As the strong alcohol entered their stomachs, every member of the Lin family turned red in the next second!
Even Su Xiaonuan is no exception!
The smell of alcohol seemed to be churning through the limbs and bones in the body, making the Lin family members feel as if they were in the clouds after drinking the alcohol!
“Good wine!”
All the Lin family members who had drank almost shouted in unison!
The sound was so loud that even the workshop was shaken by slight tremors!
