Return to the countryside to engage in industry

Chapter 265 High-end Liquor
Zhang Mingkang and other people in the company roughly guessed the new baijiu product Yang Zhenyu mentioned. The possibility of small bottles of baijiu is very high. Yang Zhenyu mentioned it more than once at the work meeting, and it has not been produced for a long time. One is because the current production of the distillery is limited. The second is not finding the right opportunity.

They could hear from Yang Zhenyu's tone that the opportunity had come now.

Yang Zhenyu returned to his office, just sat down and took a sip of water when the system screen popped up.

[Level of getting rich: 4]

【Get rich experience: 3000/10000】

【Working time: 3000h】

[Congratulations to the host for raising the wealth level]

[The richness level reaches level 4, and every 1000h of labor will get a chance to draw a lottery. The host can draw related items according to his own needs. Item attributes: special grade! 】

Yang Zhenyu finished reading the information on the system panel.

His level of getting rich has been raised to level 4. If calculated based on an average of 8 hours of work per day, it takes about four months to get a chance to draw a lottery. The time is getting longer and longer, but the reward attributes given are also consistent.

According to the system introduction, the subsequent rewards can be based on their own ideas to extract related items, which is more convenient and practical, and it is also a special treasure box, maybe it is a more magical item.

After Yang Zhenyu understood, he didn't think too much about it. There was another chance to draw a lottery, so he just clicked to draw.

[Congratulations to the host for obtaining the advanced brewing treasure chest x 1]

Another new thing.

Yang Zhenyu clicked to open.

[Congratulations to the host for obtaining the microbial flora catalytic device]

[Item introduction: The type, speed, scale, etc. of the microbial flora can be selected and adjusted according to the brewing needs. 】

【Applicable objects: brewed products】

An object similar to an electric light was floating in front of Yang Zhenyu's eyes with a dim yellow light.

After reading the article introduction, the first thing Yang Zhenyu thought of was wine making. This "microbial flora catalytic device" is very suitable for wine making.

Although Yang Zhenyu doesn't know how to make wine, he has a thorough understanding of the theoretical knowledge of wine making.

The microbiome is so important to the winemaking process.

Take Moutai as an example. In everyone's mind, if Moutai comes out of Moutai Town, it won't be able to produce that taste, so it is not pure Moutai.

The theoretical knowledge behind this point of view is the role of microflora in winemaking.

Microorganisms related to brewing can be divided into three types according to their functions: saccharifying bacteria, fermenting bacteria and aroma producing bacteria.

These three types of microorganisms play a very important role in the quality of liquor in the production of liquor, and each performs its own duties.

Saccharification bacteria are the sweetheart.

The microbial flora that decomposes nutrients such as starch into fermentable sugars is mainly mold.

Fermentation bacteria are the leader of the alcohol group.

It is produced by the decomposition of small molecular nutrients such as glucose, and the microbial flora dominated by ethanol is mainly yeast.

Aromatic bacteria are important for wine aroma.

Various nutrient substrates are used to generate rich and complex aromas such as esters, acids, alcohols, and aldehydes to form a microbial flora, mainly bacteria.

Because of its geographical location, climatic conditions, and acquired artificial brewing conditions, Maotai Town has maximized the role of microbial flora in winemaking.

Yangjiawan Village does not have such good innate and acquired conditions. It is almost impossible to make high-quality wine purely by grain quality and master craftsman, so it is almost impossible for Yang Zhenyu to take the high-end liquor route. Therefore, when the winery was first established, Yang Zhenyu gave The market positioning is low-end liquor.

But now it is different. With this "microbial flora catalytic device", you can try to produce liquor in the cellar, improve the quality of the product, and enter the mid-to-high-end liquor market.

Yang Zhenyu came out of the office and asked Zhang Mingkang to go to the winery together.

The fifth phase of the winery has been capped. There are four boilers and two giant fermentation tanks inside. With the new production line, once the fifth phase is put into operation, the output can be doubled.

Master Chu instructed several apprentices to keep an eye on the air pressure, came out to meet Yang Zhenyu and Zhang Mingkang, and followed him to the fifth phase of the factory.

Yang Zhenyu walked into the factory and explained: "Master Chu, this fermentation tank is specially used to produce cellar baijiu, and you personally bring people to stir-fry the ingredients.

This year the company will find a way to recruit an expert in this field, and we have to go one step further. "

Zhang Mingkang and Master Chu looked at Yang Zhenyu in surprise, and then nodded in response to Yang Zhenyu's arrangement. They knew Yang Zhenyu's intention very well.

Master Chu just asked, "Director Yang, which method should you choose to store?"

Yang Zhenyu said: "Traditional pottery storage!"

There are two common cellaring methods on the market, one is the traditional clay pot cellaring method, which is used by many large-scale liquor producers today, and the other is to build several large wine containers in the valley like Langjiu The device stores liquor.

More people think that the traditional earthenware cellar is more conducive to improving the quality of liquor.

The puree wine without any substance has a good stability of wine molecules. During the cellaring process, the liquor in the container breathes the air with suitable dry humidity in the cellar through the container at a suitable temperature, and three kinds of things will happen: Variety.

The first is volatilization. Freshly steamed liquor usually contains volatile sulfides such as hydrogen sulfide and mercaptans, as well as highly irritating volatile substances such as aldehydes.

These substances can volatilize naturally during the cellar storage. Generally, after half a year of cellar storage, the existence of sulfides in the wine can hardly be detected, which greatly reduces the irritation of the liquor.

The second is the association between molecules. Alcohol and water are polar molecules. After storage, the arrangement of ethanol molecules and water molecules is gradually straightened out, thereby strengthening the binding force of ethanol molecules and reducing the activity of ethanol molecules. , so that the taste of liquor becomes soft, and at the same time, other aroma substances in liquor will also have a similar association.

When the macromolecule groups associated in the wine increase, the more polar molecules are bound, the softer and softer the wine quality will be.

The third is chemical changes, liquor can produce slow chemical changes in the cellaring process.

Ethanol generates new esters during the process of alkyd esterification. The longer the storage time, the more esters will be produced, and the aroma of the wine will be greater, which is commonly known as impurity removal and aroma enhancement.

For individuals, cellaring is the best way to store wine, and for the winery in Yangjiawan Village, it is the most direct and easiest way to increase the value of baijiu.

After talking here, Zhang Mingkang couldn't help but think of the jars of liquor he had hidden in the cave in the back mountain, and said with a smile, "Old Chu, the jars of wine in the cave in the back mountain have been stored for five years, right?"

Master Chu also thought of those jars of white wine, and nodded with a smile, "It's been seven years."

Yang Zhenyu said: "Uncle Zhang, have you hidden wine before?"

Zhang Mingkang said with a smile: "At that time, I didn't want to use it to sell money. Lao Chu and I put it there to drink it when the baby got married. Now those jars of liquor will cost at least a few hundred yuan a catty. .

Old Chu, why don't you open a pot tonight to try your mouth? "

Master Chu excitedly said, "Okay, do you or mine?"

Zhang Mingkang said, "Open mine."

Yang Zhenyu said: "It seems that I have a good fortune today."
