Distillation is a thermodynamic separation process.


    It uses the different boiling points of each component in the mixed liquid or liquid-solid system to evaporate the components with low boiling point and then condense to separate the whole component.


    It is the combination of evaporation and condensation.


    In short, it is to heat the fermented grains into wine steam, separate them from water, and finally cool them into wine!


    This is a very effective way to improve the purity of liquor.


    Because the steam separated by heating is highly concentrated alcohol separated from the water. After the wine is made, it is blended and then the real Baijiu is.


    Generally speaking, the whole distillation process is divided into three stages, which are mainly distinguished by heating temperature.


    The first stage is the distillation temperature below 78 degrees. The separated wine is the so-called wine head.


    The wine head contains a large amount of low-grade fusel oil, low-grade fatty acid fat and aldehyde, which has a certain aroma, but the miscellaneous taste is relatively heavy, which also has a certain harm to people''s vision. It is generally stored separately.


    In the second stage, the distillation temperature is between 78 and 95 degrees. The separated wine is normal distilled wine, that is, the commercial wine used for sale in Jiang Fan''s world.


    In the third stage, the distillation temperature is about 95 degrees to 100 degrees. What comes out is the end of the wine. The wine tastes miscellaneous and bitter. It will basically be connected separately and stored with the head of the wine.


    In fact, the process of distillation from beginning to end is not long in terms of time alone.


    However, it is necessary to master the intensity of the fire. At different stages, the requirements for the fire are completely different. Jiang Fan has checked this on the Internet.


    After all, it''s the first operation. It''s a little nervous.


    Jiang Fan couldn''t help taking a deep breath and carefully perceiving the change of temperature.


    There is no thermometer in this world, so that the only thing that can rely on for the control of distillation temperature is feeling!


    Su xiaonuan and others waited nearby.


    Except for the guards who must 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 can''t always do it himself. He always wants those trusted people of the Lin family to learn it, and then the Lin family will preside over the brewing workshop.


    As for outsiders, Jiang fan does not intend to teach this brewing technology.


    Even this way will limit the output of wine, but since this high Baijiu is the first time to appear in the world, then it is sure to take the high-end line.


    The selling price is bound to be very exaggerated. Except for dignitaries, it is absolutely impossible for ordinary people to afford it.


    In this way, the problem of wine production is not a problem.


    In less than half an hour, the whole distillation process has been completed.


    The distilled liquor did not directly seal the altar, so that the aroma of the wine spread throughout the workshop!


    This aroma makes people feel as if they are floating and refreshing!


    Even Jiang Fan, who is totally bad at wine, can''t help swallowing his saliva.


    Not to mention Su xiaonuan''s group of people, their performance at this moment is even worse!


    After hesitating and storing the head and tail of the wine separately, Jiang Fan couldn''t resist his curiosity. He took a wine spoon, scooped some new wine about one or two, and tried to taste it.


    It''s delicious!


    It''s really delicious!


    Although Jiang fan is not good at wine, he is born in Beijiang province and has a natural capacity for drinking.


    Baijiu Erguotou, from all over the world, has drunk a lot of various kinds of liquor. When it comes to Moutai Wuliangye, it goes to the head of the village Erguotou, basically no matter how much, he has at least tasted it.


    Chiang fan is very sure that no matter what kind of Baijiu he has drunk in his own world, he has not brewed this good wine at this moment.


    It can even be said that it is very different!


    The degree of wine is not low, about 70 degrees. It should be blended again.


    But now it is still the original pulp, but the entrance is very soft. You can''t feel a little spicy. While the aroma is pungent, the taste is very refreshing.


    But after swallowing it, the strength of the wine suddenly spread, and the whole body was swelled by the heat wave.


    The wine gas punch made Jiang Fan slightly in a trance, but it was just a mouthful, so he immediately returned to normal.


    Staring at the remaining wine in the wine spoon, Jiang Fan feels very difficult to understand.


    The way you choose to make wine is actually very rough.


    Basically, there is no technical content.


    No matter the brewing process, the fineness of the whole process, or even the extraction link of the liquor itself, there is nothing worthy of praise.


    Don''t compare with the hardcover wine of the world, even if it is compared with those Baijiu liquor produced in Beijiang province.


    After all, this is my first wine making. Before that, I have no experience.


    But why... The wine made is so excellent?!


    Think of the unusually short fermentation time. Even when Jiang Fan tasted the liquor that had not been distilled just now, he found that even if the fermentation time was so short, it was still long


    So... What key factors have you overlooked?


    Looking at Jiang Fan, after tasting the wine, he suddenly fell into meditation. Lin Wanqing thought it was the poor taste of the wine, which hit Jiang Fan.


    He hurriedly said, "brother Jiang Fan, it doesn''t matter if the wine is not brewed well. Anyway, it''s just a try. Besides, even if it''s not brewed well, it''s much better than Heyang Daqu. Don''t take it to heart."


    "Not brewed? Who said not brewed?"


    Jiang Fan''s thinking was interrupted and asked with a surprised face.


    "Ah? I think brother Jiang fan doesn''t seem satisfied after you taste it, so I think it may be the problem of wine..."


    Lin Wanqing said in a daze.


    "I''m not dissatisfied. I''m so satisfied. I didn''t expect that the wine would be so delicious. Come on, everyone try it."


    Jiang Fan smiled and greeted other Lin family people in the workshop to see if there was something wrong with his taste buds.


    In Shaoqing, the Lin family in all the workshops made two or two drinks respectively, and then drank them all one by one. It was not like Jiang Fan who had just used the delicate way of "sipping".


    With the liquor into the stomach, the next second, everyone in the Lin family turned red!


    Even Su xiaonuan is no exception!


    The smell of wine seemed to keep churning around in the body, which made the Lin family people who drank the wine feel a little happy in the clouds for a while!


    "Good wine!"


    All the people of the Lin family who drank the wine almost shouted out in unison!


    The sound was so loud that the workshop was shocked and there was a slight tremor!
