Many friends mistakenly think that 12-degree beer contains 12 degrees of alcohol concentration. In fact, the degree of beer and the degree of liquor are two different things. The degree of liquor is its alcohol content. The "degree" indicated on the beer trademark "It does not refer to the alcohol content of the beer, but to the concentration of wort after saccharification. For example, one kilogram of wort contains 120 grams of sugar, which is 12 degrees. According to the concentration of wort, beer is divided into three types: low concentration (6-8 degrees), medium concentration (10-12 degrees) and high concentration (14-20 degrees).

There is also a certain relationship between wort concentration and alcohol concentration. Generally, the alcohol content of low-concentration beer is 2 degrees, the alcohol content of medium-concentration beer is 3.1-3.5 degrees, and the alcohol content of high-concentration beer is 4-5 degrees. How to drink beer

Nowadays, my country's beer production has ranked second in the world. Beer is no longer a strange beverage. It has entered thousands of households and has become an indispensable drink in people's lives.

There is also knowledge in drinking beer. If you understand it, you can enjoy drinking beer and avoid some unpleasant accidents.

First of all, let’s start with choosing beer. Do not shake the beer vigorously when you pick it up. Especially in summer, the temperature is high and the pressure inside the bottle is high. If the bottle is not of good quality, it will cause an explosion and hurt people. You can turn the bottle gently. Look at the label and check the clarity of the beer.

The national standard stipulates that beer has a shelf life of four months. Beer within the shelf life is generally a qualified product. Now many manufacturers’ beer has a shelf life of one year or more, but fresh beer tastes better. If beer leaks, loses luster, settles, tastes sour and other quality problems occur during the shelf life, you can directly contact the manufacturer or store for replacement or compensation. Some beers that have exceeded the shelf life are not necessarily undrinkable. If the appearance of the beer is clear and transparent, the taste will not be the same. If there is not much change, you can drink it, but of course the taste will not be as good as fresh. If it is cloudy, precipitated, or tastes sour and deteriorated, you cannot drink it.

Purchased beer should be placed in a cool, dry place, and special attention should be paid to prevent direct sunlight. Beer exposed to direct sunlight will oxidize and produce a smell like persimmons, commonly known as "sunlight odor". The beer you bring in must be drunk first and should not be left for a long time.

It is best to use a transparent and clean glass to drink beer. In a transparent glass, you can observe the rising of the foam and appreciate the golden and shiny color of the beer. The cup must be clean and free of oil stains, otherwise the carbon dioxide gas in the beer will lose surface tension due to contact with oil, causing the beer foam to disappear quickly.

Use a bottle opener to open the beer, do not bite it with your teeth, and do not use two bottle caps to hit it to avoid damaging your teeth, and more importantly, avoid being injured by an explosion. Similar accidents have happened before. Recently, "Guangzhou Daily" reported that a British and German migrant worker working in Guangzhou used his teeth to bite open the bottle cap. Suddenly there was a loud "bang" sound, and he suddenly felt a sharp pain in his throat and blood. Immediate outflow, bilateral tonsils and the junction of tongue and hip were lacerated, causing deep pain.

The method of pouring beer is to slowly pour it into the cup at a distance of 3cm from the mouth of the bottle. Do not use too much force. In this way, you can observe the rise of foam when pouring beer and appreciate the white and delicate foam. People Known as the "beer flower", you can smell the aroma of malt and hops, and then drink it in large sips. You will feel palatable and refreshing when you drink it, and the taste is mellow but not monotonous. After drinking, you will feel a little numb. The feeling, commonly known as "killing the mouth", brings people a soft, refreshing, comfortable and pleasant feeling. Beer should be drunk alone. It is not advisable to add juice, soda, or cola before drinking. Beer is a low-alcohol beverage. The alcohol content is mostly 2-5%. You will not feel much alcohol stimulation when drinking it, but it also has stamina. Overdrinking can also make people intoxicated. Drunk.

What is the appropriate temperature for drinking beer? Usually people like to drink cold beer, that is, refrigerating the beer to 8-15℃, which makes it more comfortable to drink. If the temperature is too high, it will taste rough and the mixed taste of the beer is easily exposed. If the temperature is too low, the taste will be uncomfortable. If the mouth is frozen, it is commonly known as "ice teeth".

According to experiments, when beer is frozen below 3°C, the flavor of the beer changes and it becomes difficult to foam. After the beer is frozen, the ice volume increases and it is easy to leak or break. Therefore, do not freeze the beer in the refrigerator. Cool down in layers to avoid bursting.

Beer can be consumed daily before meals or as a drink to relieve heat and quench thirst. The amount of beer consumed at one time should not be too much, generally no more than 1 liter. Beer should be drunk immediately. If the beer is opened for too long, the carbon dioxide gas will escape, making people feel bitter and tasteless. Especially in summer, the climate is hot, which can easily lead to microbial infection and is unhygienic. Nutritional functions of beer

Everyone knows that beer is known as "liquid bread". In life, consumers are not very clear about the functions of beer.

1. Hygiene.

Beer is made from natural raw materials and produced under conditions that absolutely meet hygienic standards. It is an absolutely reliable natural pure food.

2. Quench your thirst.

Beer has a high water content (more than 90). It clears the fire and moistens the throat. A glass of wine in summer is just refreshing and cool, and the feeling is wonderful.

3. Refreshing.

The CO2 and organic acids in beer have refreshing and refreshing functions. On the one hand, drinking it in moderation can reduce excessive excitement and tension, and promote muscle relaxation; on the other hand, it can stimulate nerves and promote digestion.

4. Help digestion.

The main raw materials used in the production of beer are barley, alcohol, hop components and polyphenols, which can increase gastric juice secretion, stimulate gastric function, and improve its digestion and absorption capacity.

5. Diuretic.

The low content of sodium, alcohol, and nucleic acids in beer can increase the blood supply to the brain, expand the coronary arteries, and accelerate the body's metabolic activities by stimulating the kidneys with the supplied blood.

6. Lose weight.

Among various weight loss methods, beer can have a good weight loss effect. This is because it contains very little sodium, protein and calcium, and no fat or cholesterol. Very effective in inhibiting excessive body growth. It makes no sense to say that drinking beer “brings you a big belly”.

7. Disease prevention.

According to an experiment at the Imperial Permanente Medical Center in Oakland, California, the United States shows that moderate beer drinkers are less likely to have heart disease and ulcers than teetotalers and alcoholics, and can prevent high blood pressure. and other diseases. Types of Beer my country’s latest national standards stipulate that beer is brewed from barley malt (including special malt) as the main raw material, added with hops, and fermented by yeast. It contains carbon dioxide, is sparkling, and has a low alcohol content (2.5~ 7.5) of various types of fresh beers.

Beer is the largest-selling low-alcohol beverage in the world today. There are many varieties. Generally, it can be determined according to the production method, product concentration, beer color, beer consumption target, beer packaging container, and beer fermentation materials. Depending on the type of yeast.

Beer can be divided into:

1. Pale beer

The color of light beer is 5￣14 EBC units, such as high-concentration light beer, which is the original wheat Beer with a juice concentration of 13% (m/m) or above; medium concentration pale beer, beer with an original wort concentration of 10~13% (m/m);

Low concentration pale beer, which is original wort Beer with a concentration of less than 10% (m/m);

Dry beer (beer with high fermentation degree), pale beer with an actual fermentation degree of more than 72%;

Low alcohol beer, Beer with an alcohol content of less than 2% (m/m) [or 2.5% (v/v)].

2. Strong-colored beer

The color of strong-colored beer is 15~40 EBC units, such as:

High-concentration strong-colored beer, original wort concentration is 13 Strong-colored beer with a concentration of 13% or more (m/m);

Low-concentration strong-colored beer is a strong-colored beer with an original wort concentration of less than 13% (m/m);

Strong-colored dry beer (high fermentation degree beer), a strong-colored beer with an actual fermentation degree of more than 72%.

3. Dark beer

The color of dark beer is greater than 40 EBC units.

4. Other beers have certain changes in raw and auxiliary materials or production processes to become beers with unique flavors. For example:

Pure draft beer: This is beer that can achieve a certain biological stability without heat treatment and sterilization in the production process.

All-malt beer: Beer made entirely of malt (or partially replaced by barley) and brewed by saccharification by leaching or boiling.

Wheat beer: Beer brewed with wheat germ as the main raw material (accounting for more than 40% of the total raw materials) and using top fermentation or bottom fermentation.

Hazy beer: This kind of beer contains a certain amount of live yeast in the finished product and has a turbidity of 2.0~5.0 EBC turbidity units.

According to the production method, beer can be divided into fresh beer and cooked beer. Fresh beer refers to beer that is packaged and sold without low-temperature sterilization (also called pasteurization). This type of beer is generally sold on-site and should not be stored for too long, usually one week at low temperatures. Cooked beer refers to beer that has been sterilized at low temperature after being packaged. It can be stored for a long time, up to about three months.

According to the packaging container of beer, it can be divided into bottled beer, barreled beer and canned beer. Bottled beer is available in 350ml and 640ml sizes; canned beer is available in 330ml size.

According to consumption targets, beer can be divided into ordinary beer, non-alcoholic (or low-alcohol) beer, sugar-free or low-sugar beer, sour beer, etc. Non-alcoholic or low-alcohol beer is suitable for drivers or people who cannot drink alcohol. Sugar-free or low-sugar beer is suitable for people with diabetes
