In the evening, we went into the winery and started the final step of distilling the liquor.
The methanol content in the first liquor is too high, and the tail liquor contains more fusel alcohol.
Ning Xiyue remembered what Master Chen said about cutting off the head and tail when distilling liquor and storing it separately.
The first batch of wine is made at the ratio of ten catties of grain to one ounce of wine. She has forty catties of sorghum, which means four ounces.
She picked up the graduated glass on the workbench to receive the wine. Four ounces of wine was about 222 milliliters.
Ning Xiyue controlled the amount precisely, and when the scale reached 222 milliliters, she removed the glass and replaced it with a glass wine jar.
At this time, the distilled wine can be kept and drunk.
The four liang of wine in her hand could be kept as alcohol. Ning Xiyue put it away and carefully observed the distilled wine.
According to the yield recorded in Mr. Chen's experience book, the yield of her light-fragrance wine is about 50%.
If we calculate based on half of it, she can produce 20 kilograms of wine with a concentration of about 50% from 40 kilograms of sorghum.
Because of different fermentation conditions, the wine yield fluctuates.
When the amount of wine in the jar reached about 20 kilograms, Ning Xiyue paid special attention to the color of the wine and the production of the wine.
According to her experience, Ning Xiyue moved the jar away and replaced it with a glass jar when the wine weighed 21 kilograms.
She thought that the wine that came later was the tail wine, which contained too much fusel alcohol and could not be drunk, so she could only save it to be mixed into the next distillation.
Ning Xiyue took out a measuring cylinder, thermometer and alcohol meter to test the alcohol content.
The alcohol content of the wine brewed this time was 52 degrees, while the alcohol content of the wine that followed was measured to be less than 50 degrees, so it can be confirmed that it was the tail wine.
After the distillation, Ning Xiyue kept the sorghum dregs and asked the robot housekeeper to clean them up and use them to feed the pigs.
It’s great to have pigs in the space. You can feed the pigs with anything you don’t want, without wasting anything. You can also raise the pigs to be fat and white.
After cleaning up the winery, Ning Xiyue looked at the freshly brewed jar of wine and thought of the original intention of making this wine, which was to exchange it for a big gift package. She wanted to ask how to exchange it, but stopped before she could say anything.
After thinking about it, Ning Xiyue took two jars of wine each containing ten kilograms before the bell rang, and divided the twenty kilograms of wine equally into the two jars.
A jar holds ten kilograms, so she has two jars of wine. Tongzi didn't say how many kilograms he would exchange for it, he just said it was one jar of wine.
Brewing wine takes a really long time, and she wanted to keep some of the wine she brewed for the first time as a souvenir.
It should also be feasible to use a jar of ten kilograms of wine to complete the task.
Let’s try it first and see if it works.
Ning Xiyue looked at the little turtle who was watching the replay of her wine-making process with great interest. The little turtle didn't notice her intention at all and clapped his hands in satisfaction.
After she sat down, she asked loudly, "Tongzi, the wine is already brewed. How do I redeem the mysterious gift package we promised you?"
