Wine and rice wine belong to brewing wine, which is made from grapes, fresh fruits and rice by fermentation, respectively, and its alcohol is directly fermented from the raw materials. Wine and rice wine are generally fermented at 11-12°C. In the case of wine, grapes with different sugar content can produce different alcohol concentrations, and of course different concentrations of alcohol can also be produced by adding sucrose.

When all the sugars in the raw materials are fermented or only a small part of the residual sugar remains, the yeast has no available sugar, that is, it stops fermentation without the required nutrients. Baijiu is a distilled spirit, which is obtained by distillation of fermented mash or fermented mash made from starch or sugar raw materials. The distillation of the original liquor is generally graded, and finally blended into different degrees according to the needs of the product.

I hope I can help you, good luck!

The alcohol concentration of liquor is controlled during the production process, and as distillation progresses, the alcohol content gradually decreases, and usually the liquor content is controlled above 60 degrees every day by the brewer, and then it is collected in the liquor warehouse for storage.

I haven't made rice wine, and I guess it's about the same as white wine.

Wine and beer should be related to yeast.

The difference in alcohol concentration during brewing is mainly controlled by process operations, such as baijiu (especially solid-state brewing) which is operated when distilling distilled distillery and extracting liquor, which is artificially controlled.

It is limited by the materials used to make different wines, and the concentration of alcohol produced during the fermentation process is also different.

The concentration of alcohol is the volume ratio of alcohol 96, which is equivalent to 96 volumes of alcohol and 100 volumes of wine, 96 x = 95 100, and x-100 is the volume of water.

Answer: The concentration value of 95% alcohol is expressed in the number of body fractions in the spring (%). That is, 100 ml of fiber solution contains 95 ml of alcohol.

Alcohol dilution is the process of preparing a high concentration (95%) of alcohol (95% wine culture mold with a 500ml package) and a certain volume of water to prepare a low concentration (such as 75%) alcohol.

For example, to prepare 100 ml of 75% alcohol: calculate the volume of 95% alcohol v = (75%x100ml) 95% = ml

Dilution operation: Add ml to a 100 ml dry and clean graduated cylinder95% alcohol, diluted with distilled water to 100 ml of engraved lines. It is then transferred to a reagent bottle and labeled.

Alcohol with a concentration of 75 is best used for sterilization, because too high a concentration will cause the bacterial protein shell to solidify, and the alcohol will not be able to penetrate deep inside. If it is too low, there will be too little alcohol to effectively sterilize.

What is the difference between different concentrations of alcohol?

What is the difference between different concentrations of alcohol?

The preparation of raw materials and processes is different, industrial alcohol is prepared by cracking raw coal or petroleum, which contains a large amount of methanol, formaldehyde and other impurities, and is not easy to separate; Medical and medicinal alcohol are now prepared by saccharification and enzymatic fermentation of corn or other grains, with few impurities;

Industrial alcohol can never be taken because it contains methanol and other harmful substances to the human body, and can only be used as raw materials or fuel for non-edible chemical industries; At this stage, medical and medicinal alcohol are products that are in line with edible alcohol, and there is no special one, which can be used for drug production, or it can be diluted into 75% medical disinfectant alcohol in proportion.

Alcohol is ethanol in medical practice. Therefore, 75% alcohol is mainly used in medical treatment. There is also absolute ethanol.

Industrial alcohol, on the other hand, is mainly 95% alcohol, which is commonly referred to as alcohol. We can also dilute 95% alcohol to 75% alcohol. 95% of the milliliter plus water for injection is diluted into 100 milliliters, which is 75%.

The composition of industrial alcohol is ethanol and methanol, and medical alcohol (75% or 95%) is composed of ethanol and water. The aroma of methanol is similar to the aroma of alcohol, but it is light and softer. Its taste is also similar to that of ethanol, which is not easy to distinguish in the senses.

In terms of diet, if it is suspected of being methanol or industrial alcohol, it should be sent to the food quality inspection department for physical and chemical inspection and judgment.

Extended information: methanol has strong toxicity, the greatest impact on the human nervous system and blood system, it will produce toxic reactions through the digestive tract, respiratory tract or ** ingestion, methanol vapor can damage the mucous membrane and vision of the human respiratory tract. Symptoms of acute poisoning include: headache, nausea, stomach pain, tiredness, blurred vision, blindness, followed by difficulty breathing, and eventually paralysis of the respiratory center and death.

Chronic toxic reactions are: dizziness, lethargy, headache, tinnitus, decreased diversion, and digestive disorders.

The degree of wine indicates the percentage of alcohol in the volume of the wine, which is usually expressed in the volume ratio of 20, such as the 50 degree wine, which indicates that in 100 ml of wine, it contains 50 ml of ethanol (20).

The alcohol content can also be used as a weight ratio, and the weight ratio and volume ratio can be converted to each otherThe proof of beer and the proof of liquor are two different things, the proof of liquor is its alcohol content, while the proof of beer actually refers to the wort concentration. The definition of alcohol alcohol is the percentage of the volume of pure ethanol (alcohol) contained in the wine.

For example, the pure ethanol content in 100 ml of wine is 10 ml, and the alcohol content of this wine is 10°, but the capacity increases and decreases with the temperature. China's regulations are to detect at a temperature of 20. That is, at 20 hours, how much pure ethanol is in 100 ml of wine!

The amount of sugar in the grape fruit is the factor that restricts the alcohol content of the fermented wine.

The alcohol concentration of wine is usually between 8% and 15%, but the alcohol concentration of fortified wines (such as port wine in Portugal, sherry wine in Spain, bowl wine in Australia, etc.) is relatively high, about 18% to 23%, while sweet white wine in Germany is generally lower in alcohol content, usually below 10%.
