There are likewise two types of alcoholic fermentation.

One is the preparation of the wine mother.

The sake mother is the yeast that is added to ferment the mash after the expansion of the culture, and the production needs to be expanded three times before it can be added, which is called the primary culture (test tube or triangular bottle culture, secondary culture, tertiary culture, and finally the culture with the mother barrel.

First-level culture, about 10 days before production, select ripe and non-spoiled fruits, press and extract juice.

Fill into clean, dry-heat sterilized tubes or triangular bottles.

The tube is 1/4 and the triangular bottle is 1/2.

After loading, sterilize in boiling water under atmospheric pressure for 1 hour or 58kPa for 30 minutes.

After cooling, the culture is inserted and the juice is shaken to disperse. Cultivation is carried out, and when fermentation is vigorous, it can be used for lower culture.

Secondary culture, 1/2 juice is filled in a clean, dry heat sterilized triangle bottle, and the above culture medium is connected to the culture.

For tertiary culture, clean and sterilized large glass bottles of about 10L are selected, and juice is added to about 70% of the volume after being filled with fermentation suppositories.

Sterilize by heat or with sulphurous acid, the latter should contain 2150 mg of SOs per liter of juice, but leave it for one day.

The bottle mouth is disinfected with 70% alcohol, and the secondary strain is inserted, the dosage is 2%, and it is cultivated in the incubator, and after the reproduction is vigorous, the total use is expanded.

The other is fermentation equipment.

Fermentation equipment should be able to control temperature, easy to wash, drain, and have good ventilation.

It should be cleaned before use and disinfected with SO2 or formaldehyde fumigation.

The fermentation vessel can also be made for both fermentation and wine storage, which requires no leakage, can be sealed, and does not play a chemical role with the liquor.

There are fermentation barrels, fermentation tanks, and special fermentation equipment, such as rotary fermentation tanks, automatic continuous circulation fermentation tanks, etc.

Fruit juice fermentation is divided into main fermentation and post-fermentation.

During the main fermentation, the juice is put into the container, the amount is 4/5 of the volume of the container, and then 3%-5% yeast is added, stirred evenly, the temperature is controlled at 20-28 °C, and the fermentation time varies with the active fruit wine and fermentation temperature of the yeast, generally about 3~12 days.

When the residual sugar drops below 0.4%, the main fermentation ends.

Then post-fermentation should be carried out, that is, the wine container should be sealed and moved to the wine kiln, and it should be left at 12~28 °C for about 1 month.

After fermentation, it is clarified in the same way as fruit juice.

The fruit wine blended in the finished product is mainly blended and adjusted.

Blending refers to the selection of the original liquor and the mixing of the appropriate proportions, and adjustment refers to the adjustment of certain components of the blended liquor according to the product quality standards.

Blending is generally to select a raw liquor with close quality to the standard as the base liquor, select one or several other liquors as the blended liquor according to its shortcomings, add a certain proportion and then conduct sensory and chemical analysis to determine the proportion.

The adjustment is mainly based on alcohol content, sugar, acid and other indicators.

The adjustment of alcohol content is best to use the same variety of wine with high alcohol content for blending, can also add distilled liquor or alcohol, if the sugar content of sweet wine is insufficient, with the same variety of concentrated juice for the best effect, can also use granulated sugar, depending on the quality of the product, insufficient acid can be used citric acid.

After the mother barrel is sterilized with SO2, it is loaded with 12-14oBx juice and incubated at 28-30 °C for 1~2 days to be used as the production mother.

After culture, the mother can be directly added to the fermentation broth, and the dosage is 2%~10%.

Finally, filtration, sterilization, and bottling.

Filtration includes diatomaceous earth filtration, thin plate filtration, microporous membrane filtration, etc.

Fruit wine is often packaged in glass bottles.

When bottling, the empty bottle is soaked in 2-4% lye at a temperature above 50 °C, then cleaned, drained and sterilized.

The wine can be pasteurized before being bottled hot or cold.

Fruit wines with low alcohol content should also be sterilized after bottling.

After looking at the brewing method of fruit wine, Ye Luo is always a little bit, but in his opinion, such a method is too troublesome and complicated, and it also requires a lot of tools.

To make him even more depressed, he found that he didn't even have a tool on the island.

However, he found that like his grandmother, it was a traditional folk way of brewing, and what he read on the Internet was for sale.

The former is simple, the latter is complex.

Ye Luo couldn't decide which one to use to make fruit wine for a while.

Either way, he didn't have the tools right now, and he didn't think about calling Rockhudson to send them, but considering that these things were not necessarily available in Newfoundland, it would definitely take a lot of time to find them, and it was still a question of whether they could be found.

Of course, the main thing is that Ye Luo wants to be lazy.

In addition, he knew that it was not easy to buy liquor in Newfoundland, although it could be bought in some stores, but that kind of liquor was the kind of liquor in the 20s to 40s, which was used to drink, and it was a bit choking if it was used to make wine.

You must know that the degree of liquor for brewing is basically not less than 50 degrees, and this kind of liquor with a high number of liquor is rare even in China, let alone Newfoundland.

Not to mention the equipment for brewing.

As an island known for its seafood, if it is those fishing things, you can find them almost everywhere, and the equipment for making wine may not be found in the whole of Newfoundland, and he does not want to make trouble for Rock Hudson.

However, Ye Luo did not give up the idea of brewing, but hit the idea in the system mall.

After opening the super mall and looking for it for a while.

I don't know if I don't see it, and I'm shocked when I see it.

The price of brewing equipment is from a few points to tens of thousands, and there is no idea how many kinds of leaves fall, only that the number of 999+ pages is showing their majesty!

Although there are many of them, and the price is also high and low, there is really nothing that can make him look good.

On the one hand, this thing is not used after buying it and brewing it once, and it is too wasteful to put it away.

On the other hand, he really doesn't plan to start a new 'business', although he knows that 'tobacco and alcohol' is very profitable, but this thing needs to be marketed.

Not to mention that there are not enough manpower now, even farms and pastures are still developing, where can there be that effort to spend on winemaking, and when others have enough manpower in the future, it is not too late to think about this aspect.

Anyway, these devices can be bought at any time as long as they have a reputation, so you don't have to worry about having nowhere to buy them!

Ye Luo, who is not very interested in these brewing equipment, plans to see if there is anything simple.

After looking for a while, he really found a kind of koji.

This kind of koji can not only ferment, sterilize, accelerate the fermentation time, but also enhance the taste of fruit wine, it can be said that almost saving most of the process for Ye Luo, and the price is not expensive, ten points of prestige and ten pieces, on average, a piece of prestige and a little prestige.

There must be more than one kind of koji in the city, so Ye Luo didn't buy it right away, but planned to look at the others.

There are not as many types of koji as before, on the contrary, there are very few, no more, no less, just ten kinds, and the price is from ten to one hundred prestige!

In less than five minutes, Ye Luo finished reading all the koji, and found that most of the koji had similar effects, and the more expensive the price, the shorter the time to become wine, and the greater the improvement in texture and taste!

Ye Luo didn't think about it at all, and directly spent 100 to buy the top quality koji, and it only took three days from brewing to finished wine.

After buying koji, Ye Luo thought that there was no big glass bottle for sake brewing on his island, and he easily found it in the mall.

It can be as small as ten centimeters and as large as ten meters.

Ye Luo likes two kinds, one is about half a meter high and about 30 centimeters wide, and the other is one meter high and half a meter wide.

As for the less than half a meter, all the above one and a half meters were given up by him.

The small ones are not enough to drink, and the big ones are too troublesome to brew.

Unfortunately, he's a troublesome man.

Eventually, Ye Luo decided to buy the one-meter-tall kind.

Even with the drunkards of Daxter, it would be enough for them to drink with themselves for days.

Although fruit wine is one of many wines, it can't stand the sweetness of others, and he knows that the women in his house drink well.

Usually when they drink with Daxter, they will also drink a few glasses with them, whether it is beer, foreign wine, or wine.

Compared with the previous two, they choose more wines.

As for whether this thing has the kind of skin beautifying effect they said, it is not clear that this leaf falls.

Anyway, he knew that as long as he drank wine, whether it was Scarlett, Xia Xiaofei, or Kailin Sina and Shanna, they would normally choose wine.

No, no, Shanna and the others are not picky, it may have something to do with being soldiers, they can drink any kind of wine, and the amount of alcohol they drink is quite scary.

At least Ye Luo knew that except for Renison and Karn, who were also soldiers, they could win steadily, and like Daxter, they were half evenly matched.

Of course, he is exceptional!

Because of the system, Ye Luo found that drinking alcohol was similar to drinking water, although every time he drank, he would get on his face and look like he was about to get drunk, but in fact he was very sober.

The price of glass bottles for brewing is even cheaper than Ye Luo imagined.

A little prestige can buy ten bottles!

On average, the price of each bottle is only 0.1 prestige, which is not a bad intention.

However, if you exchange it for money, then the price is expensive.

10,000 yuan for a little prestige, then each bottle is 1,000 yuan.

A thousand pieces may be a bit much for the average person, and a drizzle for Ye Luo.

After buying the koji and bottles, they didn't take them out immediately, but called a few of them and asked them to come and help them pick the fruit.

Soon, in addition to Daxter, who left the island, Renison, Thomas, Wiggins, and Robert all arrived.

To Ye Luo's surprise, even Karn, Sith, and Lore, who usually act as security personnel, also came over to join in the fun.

Counting a few of them plus Ye Luo, there are a total of eight people.

Ye Luo asked them to pick one by one, and the remaining two would be seen after they finished picking.

The eight of them worked in full swing, and it took about an hour to pick all the fruits.

There are ten kinds of lychees, grapes, bayberry, plums, apples, cherries, blueberries, hawthorns, pears and citrus, each of which is at least 100 catties.

If it weren't for the number of bottles, it would be ten, and Ye Luo would pick every fruit back if he couldn't do it.

As for what fruits can be used to make wine, he knows that as long as there is water, fruits can be used to make wine!

Although Renison and the others, who returned to the yard, were confused, they found that Ye Luo didn't say, so naturally they didn't ask, but washed the fruit under Ye Luo's instructions, dried it, and when it was almost over, Ye Luo went into the house and took out the bottle in the system baggage.

With the help of Renison and others, after putting the dried hundreds of catties of fruit into the glass bottle one by one, there were still about five or six catties left, and some of the leaves were left, and the rest was taken back by Renison and the others to eat.

After Renison and the others left, Ye Luo took out the koji, put a slice in each bottle, and then closed the lid, and was done!
