Why is malt added in beer fermentation Why wort is used What is the role of wort?

Malt is made by drying and rooting barley after it has been sprouted and chosen as the main ingredient for beer brewing for three main reasons:

1.Barley is not the main food crop for humans, and making wine from barley does not affect human rations**.

2.Traditionally, the 16th-century German Beer Purity Law, which stipulates that only malt, water, hops and yeast can be used for beer brewing, is still in force in Germany and has a great impact on the world.

3.The barley malt itself has a number of factors that are suitable for brewing: a suitable leaching rate; Complete enzyme system, convenient saccharification; The leather shell is not difficult to separate, which is convenient for filtration and so on.

It can be replaced by others, for example, some domestic factories are replaced by wheat sprouts, and many countries in Africa are replaced by sorghum sprouts, etc., the sugars you say can only be used as auxiliary materials, and cannot completely replace germinated grains, because these grains are needed to provide the necessary nitrogen-containing substances and low-molecular polysaccharides.

Wort is the predecessor of beer, to make beer to do wort first, called saccharification, the main role is to decompose the polymer polysaccharides in the raw materials into monosaccharides, disaccharides and trisaccharides that can be used by brewer's yeast, as well as some low-fraction polysaccharides that give beer taste, so as to carry out the following fermentation, brewer's yeast can not directly use polysaccharides above the three sugars.

Malt contains enzymes, and when saccharification, it needs to be broken down by enzymes to complete the sprinkling.

Sugar can only be used as an adjunct, and only a little can be added at a time, not too much. Rice and corn can also be used as adjuncts.

Rice is most suitable as an adjunct (but with a high gelatinization temperature).

Corn has a color flavor (can't add more).

I'm a beer major, so if you have any questions, you can m me.

It can be used as an adjunct, but malt cannot be replaced.

The beer production process is divided into malt manufacturing, wort manufacturing, pre-fermentation, post-fermentation, filtration sterilization, packaging and other processes.

Malt manufacturing: Barley (also wheat is being tested for use) is impregnated and absorbed, germinated at a suitable temperature and humidity, and various hydrolase enzymes are produced during germination, such as protease, saccharification enzyme, glucanase, etc., which can decompose the protein of the malt itself into peptides and amino acids, and decompose starch into low-molecular substances such as dextrin and maltose. When germination reaches a certain level, germination is stopped and dried to make malt with a low moisture content.

Wort manufacturing: the malt is properly crushed, warm water is added, and at a certain temperature, the enzyme preparation of the malt itself is used to carry out saccharification (mainly hydrolyzing the starch in the malt into maltose), in order to reduce production costs, a certain proportion of rice flour can also be added as an adjunct (rice flour is boiled with water first). The resulting malt mash is filtered through a lauter to obtain wort, which is transported to the wort kettle, where the excess water is evaporated and hops are added.

Hops are a kind of plant flowers, added to beer, can make beer with a unique hop aroma and bitterness, at the same time, some ingredients in hops also have a preservative effect, can prolong the shelf life of beer.

Fermentation: After the wort has been cooled, yeast is added, transported to the fermentation tank, and fermentation begins. The traditional process is divided into pre-fermentation and post-fermentation, which are carried out in different fermentation tanks, and the popular practice is to carry out pre-fermentation and post-fermentation in one tank.

Pre-fermentation is mainly to use yeast to convert the maltose in the wort into alcohol, and post-fermentation is mainly to produce some flavor substances, eliminate the peculiar smell in the beer, and promote the aging of the beer.

Filter sterilization: After about two weeks of fermentation (some beers may ferment for several months), the beer is filtered to remove yeast and tiny particles in the beer, and then sterilized at low temperature (about 62), cooled, and the beer can be packaged. The packaging methods are mainly bottled and canned, as well as barrels.

The purpose of barley germination is to produce a certain amount of hydrolase enzymes inside the wheat kernel, and use these hydrolase enzymes to decompose the storage material of the endosperm and make it reasonably degraded, so as to produce raw material indicators that meet the needs of beer production and produce unique malt.

Fragrance. Make the endosperm cell wall.

Partial or total degradation makes the roasted wheat grains looser, easier to crush, and the contents more easily dissolved. Glican substances of wheat grains (mainly -dextran.

Fully degraded, so that the viscosity of the malt extract is greatly reduced. Part of the starch and protein of the endosperm are reasonably degraded to form a part of low-molecular-weight water-soluble substances, which are the main components of the wort.

The changes in matter during germination are:

1. Physical and performance changes;

2. Changes in sugars;

3. Changes in protein;

4. Hemicellulose.

and changes in the substance of glutin;

5. Dissolution of endosperm (malt);

6. Changes in acidity;

7. Other changes.

Upstairs got the right part. In general, the purpose of malt germination is to activate and decompose various enzymes. Second, it produces a unique malty aroma.

Third, the production of raw materials that meet the needs of beer production. Fourth, reduce dextran and other substances that have an impact on beer production, etc. The material changes inside are too complex.

It's hard to say clearly

Malmination is done to activate various enzymes of barley.

The raw material used in the manufacture of modern beer malt is mainly barley. In addition, some beer malt manufacturers may also use wheat, rye, and other grains. Malt is a key ingredient in brewing beer because it provides the yeast needed for beer and the sugar in the wort.

Beer cannot be brewed without malt. During malt production, the wheat kernels are soaked in warm water to allow them to germinate. After germination, the wheat kernels are dried and formed malt.

In this process, the starch in the barley is converted into sugars, which are fermented into alcohol by yeast during the brewing process. However, due to economic and production considerations, some brewers have started to use a variety of raw closed cherry seasons instead of malt. These substitutes include syrup, corn syrup, rice, and cereals such as rice, corn, wheat, etc.

These substitutes can provide similar sugars as malt, but may affect the taste and quality of the beer. Most beer lovers still choose pure malt beer.

Summary. Hello <>

The malt used in beer is mainly barley malt, not malt. Barley malt is obtained after process such as germination and drying, and contains amylase and protein, which can be converted into sugars and yeast nutrients for beer. In contrast, the quality and composition of malt are not suitable for beer brewing.

As for whether barley malt is still used now, it is actually still used. Although some alternatives have emerged in recent years, such as corn sprouts, rice sprouts, and even non-cereal bean sprouts, barley malt is still one of the most important ingredients in beer brewing. In addition, some special types of beer may have ingredients such as other cereals or fruits added to it, but barley malt is still the base.

The malt used to be malted in beer, but now why not use malt and what to replace it.

Extended Supplements:1The selection and processing of barley malt has a great impact on the quality of beer, so manufacturers will choose high-quality barley and use scientific germination and sensitive drying processes.

2.Substitutes such as corn sprouts and rice sprouts are used primarily to save costs and improve taste, but for some traditional beers, such substitutions may affect the original flavor of the original sauce. <>

Summary. Hello friends, malt for beer is still made from malt. Malt is one of the essential ingredients in beer as it is the main fermentation source of beer, and it provides the sugars and nutrients needed for a large amount of yeast required for fermentation.

Malt also gives beer its special flavor and color.

Hello friends, malt for beer is still made from malt. Malt Yinji is one of the essential ingredients in beer, as it is the main fermentation source of BeerFeng Nian Chong, which provides the sugars and nutrients required by the large amount of yeast required for fermentation. Malt also gives beer its special flavor and color.

Modern beer technology has introduced a number of new methods and techniques to improve production efficiency and control the characteristics of beer. For example, there are now some methods of malt production that use special enzymes to increase malt yield and reduce costs. In addition, some brewers may substitute some of the malt with other edible sugar sources, such as rice, corn or arrowhead root, when preparing beer.

However, these substitutes are usually only partially replaced, rather than completely replaced.

Barley does not sprout now, now what to replace with now.

It is true that other grains such as corn, rice or wheat can be used in the beer manufacturing process instead of barley, but these grains are generally only used as a supplement to the pure old malt.

Can barley be used directly without sprouting?

No, barley cannot be used directly in beer making. In beer making, barley must first be malted through processes such as germination and roasting, as malt is the main source of yeast fermentation. This may be due to the fact that during the germination process, the starch in the barley is broken down into the sugars and other nutrients required by various yeasts.

When Naya barley goes through the germination process, it becomes malt. During the malting process, roasting and processing are also carried out to produce the acidic edge and colour required for the spring-growing base, which gives the beer its special taste and aroma.

Now barley is used directly without germination, what is used instead.

In some modern beer processes, wheat or rice may be used instead of part of the malted barley.

In addition, it is also speculated that there are some special types of beers, such as malt-free beers, which do not use malt in the beer manufacturing process, while Suixiantan uses other grains or sugars as raw materials to create a different mouthfeel and taste than traditional beer.

Beer is made of malt and water as the main raw materials, is the wort concentration as large as possible?

Beer"degrees"But it refers to the concentration of the wort. Barley malt and rice, which are auxiliary raw materials for beer production, are converted into maltose through the action of maltoamylase and protease, and the sugar content is determined, such as 120 grams of sugar per liter of wort, which is 12°.

When the wort concentration is 7 ° 9 °, it is called low-strength beer. A wort concentration of 18° to 20° is called a dark beer. The higher the wort concentration, the better the nutritional value, the more delicate and persistent the foam, the mellow and soft taste, and the longer the shelf life.

Therefore, the "original wort concentration" is a hard reference for the identification of beer, and the shelf-life of the beer is determined by its concentration.

The malt content is high, and the taste is better (malt content is not alcohol content). It's just that low malt content is now the trend (to reduce costs), and low malt content caters to most consumer groups (light beer is suitable for men, women and children). <

In fact, the really delicious beer is high malt, don't believe it, please see similar to German dark beer, malt or even more than 13 degrees, in addition to dark beer, the higher the malt degree of the beer we usually drink, the more mellow the taste, of course, the higher the alcohol content, ordinary people will be slightly drunk in two bottles.

Wort concentration refers to the sugar content of wort at the end of saccharification process, the second wort concentration, the final wort concentration, the wort concentration before cooking, the boiling wort concentration, the stereotyped wort concentration, etc.

cThe raw wort in most parts of the country is 7 to 9 degrees Celsius. Therefore, in terms of taste, after so many years of industry experience, this concentration is just right, and it is not the higher or lower, the better. There are also this mainly related to the ratio of material to water, degree and cost, as well as individual hobbies.

If the wort concentration per mu is high, the cost of returning to malt will definitely be high, and then the alcohol content will be relatively high. In some places, the people like to drink a stronger wine to have a taste, and local breweries will launch such a relatively high wine.

Yes, some domestic manufacturers completely use malt instead of barley malt, while developing countries in Africa generally use sorghum sprouts, they are cheaper than barley malt, but their main disadvantage is that the protein content is high, which will cause the abiotic stability of beer is not good, and the second is that the husk is difficult to separate, and it is difficult to filter when making wort.

The reason why barley malt is used is that there are traditional factors in it:

In the Middle Ages, Germany, the country of origin of modern beer (not the so-called ancient beer of ancient Egypt and ancient Babylon), issued a law that only the four main raw materials of beer were barley malt, water, yeast and hops, and beer sold in Germany was not allowed to add auxiliary ingredients. This has a big impact on the beer brewing industry in other countries.

Second, barley is not the main direct food crop, and making wine with barley will not affect human rations**, which is also a major reason why barley has been used in modern times.

Third, barley has some properties that are suitable for brewing beer compared to other crops.
