Basic knowledge of red wine, fruit wine brewed by natural fermentation of red wine, it is a good habit to ask more questions when you first come into contact with wine. Although some questions are simple, they are most easily confused and are always asked repeatedly. So, let's introduce the basics of red wine.

Basic knowledge of red wine 1 How long is it best to finish a bottle of wine after opening it? How to store it if you can't finish eating it?

Ordinary white wine should be drunk within 3 hours after opening the bottle, and red wine should be drunk within 8 hours, otherwise the taste will become sour and the aroma will be lost. If there is really endless wine, the solution is: put the cork back into the bottle mouth and put it in the thermostat, otherwise put it in the refrigerator.

Pay attention to make the wine bottle stand upright when placing it to reduce the contact surface between wine and air. If the original cork is replaced by a vacuum cork, the flavor of the wine can be barely preserved for two or three days. (Bottle stopper vacuum extractor can be purchased online)

Sometimes when you open a bottle of red wine, there will be some sediment or wine residue in it. What happened?

There are generally two situations in which sediment or wine residue appears in wine:

One is the sediment naturally produced after wine is aged into alcohol. Some famous wines will begin to appear in about seven or eight years, while young wines that don't last long will precipitate after one or two years.

The other is wine crystal. The main reason for the formation of crystal stone is that the wine bottle is stored in a particularly cold environment, such as in a refrigerator with a particularly low temperature. The tartar crystals are irregular in shape and sometimes a little sticky. It is usually attached to the bottom of the bottle, the shoulder of the bottle, or appears at the bottom of the cork (because the bottle is flat or upside down). This crystal is completely harmless.

White wine crystal stone looks like white sugar, while red wine crystal stone appears purple crystal. These sediments will not affect the taste of wine, and will not cause any harm to human health, so it can be safely drunk.

Without a special ice bucket, will it reduce the quality and taste of wine if it is chilled in the refrigerator?

If the wine is kept in the refrigerator for a long time, it will make the cork dry, which is not good, but if it is cold, it is no problem to drink it immediately. However, we should still pay attention to: do not lower the temperature of ice such as red wine and mellow white wine, lest its fragrance and flavor will be reduced.

Wine ice bucket can feel more professional and formal, and can avoid the low temperature of wine ice, so prepare one! When using ice bucket ice wine, pay attention to the temperature and taste the wine at various temperatures. It tastes different!

How many calories does wine have?

About 80ml of ordinary wine has a calorie of about 60 kilocalories, while sweet wine (white wine) has a little more calories. A glass of beer is 195 kcal, a single serving (about 30ml) of whisky is 75 kcal, and 50ml of brandy is 125 kcal, so the calories contained in wine are common in alcoholic beverages.

But the advantage of wine is that wine is the only alkaline drink in alcoholic beverages, so it is understandable why people who are very concerned about health are all wine lovers.

Why do wines from the same winery in the same year have different tastes at different times?

This question highlights the complexity of wine. There are many factors that affect the taste of wine, the most important of which is the development of wine. Wine is alive and will change constantly in the bottle, so you will feel different tastes when you drink it at different times. Secondly, the temperature when drinking, different temperatures will affect the taste of wine; Thirdly, it is the place where wine is stored, because the wine stored in different places has an impact on their development.

Therefore, even if you drink it in the same winery at the same time in the same year, the taste may be different. There are other factors, such as drinking environment, people, side dishes, mood and so on, which will have an impact on the taste of wine.

Can pregnant women drink alcohol?

From the perspective of traditional medicine, pregnant women should avoid alcohol and tobacco. But because the alcohol content of wine is relatively low, and the tannin in red wine can dredge blood vessels, promote blood circulation, and supplement minerals and nutrients. Foreign women will drink some alcohol to supplement iron during pregnancy.

So you can drink 1~2 glasses of wine before going to bed, but you can't overdo it. Whiskey and vodka with high alcohol content should be quit, because excessive alcohol intake at one time will stimulate the heart, cause high blood pressure, increase the burden of dirt, dull the brain and nerves, and be unfavorable to fetal development.

Do white wine and liqueur need to sober up? What should I pay attention to if I want to sober up?

Generally speaking, the idea that people need to sober up is nothing more than aged red wine, and few people mention that white wine, especially sweet white wine, needs to sober up. In fact, not every kind of sweet liquor needs to sober up, and sweet liquor with average quality or young age does not need to sober up. Only sweet white wine with excellent quality and potential for decades needs to sober up.

The sweet white wine produced by Suttern has the aging potential of more than 50 years. After 20-30 years, it will produce some residues. In this case, it is necessary to sober up, mainly the process of sober up to separate the sediment in the bottle.

The sober-up process of sweet liquor is different from that of ordinary aged red wine, because the drinking temperature of sweet liquor is much lower than that of red wine. Therefore, when sweet white wine sobers up, it is necessary to ensure that both the wine and the soberer are in a chilled state. If the decanter is at room temperature, the wine will return to this temperature in a short time, and the quality of the wine will be greatly reduced.

After pouring out the sweet white wine, you should start drinking it immediately. Don't wait for a hangover, or the more you wake up, the hotter it will be. If you compare the hangover time of red wine with 30-60 minutes, you will get warm sugar and wine instead of cool and delicious sweet white wine.

If you have to sober up, it is recommended to soak the decanter with wine in ice water or put it in the refrigerator and wait for ten minutes before drinking. In fact, as long as you are happy, there is no necessary procedure.

There are traces of alcohol on the clothes. What should I do?

If the wine has just spilled on the clothes, if possible, it should be replaced immediately, sprinkled with salt, then washed with water, and then washed with washing powder or soap. If it can't be handled in time, it's best to soak it in soda water or milk before cleaning it regularly.

Why is there a plastic envelope on the bottle mouth? Why is the bottom of the bottle uneven?

There is a plastic envelope on the bottle mouth to prevent insects from biting the cork. Sometimes, there will be holes in the envelope to let the wine exchange breath with the outside world. The bottom of the bottle is concave and convex, and the wine residue can precipitate when the bottle is upright. The more wine needs to be stored for a long time, the deeper the concave and convex. So generally speaking, good wine needs to be preserved for a long time, and the bottom of the bottle is concave and convex, but the wine with deep concave and convex bottom is not necessarily good wine.

Why is the alcohol content of wine different?

Generally speaking, the alcohol content of wine is mostly between 8%- 15%, which is mainly determined by the sugar content in grape fruit.

Factors such as climate, grape variety and year in different countries and regions will lead to different sugar content of grapes and even different alcohol content of wine. For example, wines from California and Australia usually have high alcohol content, so we often see that the alcohol content of American wines is mostly 13%, and that of Australian wines is 13.5% or even14%. Countries with relatively cold climates, such as France and Germany, have low glucose content, so the alcohol content of wine is relatively low.

Basic knowledge of red wine 2 identification method 1

Main ingredients: red wine, edible alkali and water.

Other napkins

operation sequence/order

1, just put a little water in half a spoonful of household edible alkali;

2. Prepare an ordinary napkin;

3. Drop a few drops of red wine on the napkin, and the wine will spread evenly without precipitation in the middle;

4. Drop the edible alkali mixed with water on the red wine;

5. At this moment, something magical happened. If red wine turns dark blue, it is really red wine. If there is no response, then the red wine is fake.

Identification method 2 (suitable for outdoor occasions)

Put a white napkin on the table and drop a few drops of red wine. It will spread evenly. This is the real wine. That's because the fake red wine pigment particles are large, which will precipitate in the middle of the paper towel, and only the water marks will spread outward.

Fake wine on the market is basically pigment blending, so the accuracy of these two methods is almost 99%. Then why not 100%? That is, there is another possibility that if fake red wine uses grape skin pigment or other pigments that change color due to different pH values, it will not be detected, but this method is not low in cost and troublesome.

So at least we can know that if our red wine is not decolorized with edible alkali, it must be fake, there is no doubt about it.

How to identify imported red wine

First, there are no trademarks on many red wine bottles in the domestic market, which are completely products and fakes. Regular imported red wine is labeled with trademark, barcode, address, telephone number and other information issued by the State Administration for Industry and Commerce. Users can download a "I check" software with their mobile phones, and can directly scan its price and related information.

Second, look at the formalities: you can ask the dealer to show the health certificate and foreign certificate of origin of this batch of wine to confirm that the goods certificate is consistent. For all imported wines that pass the inspection and quarantine, the inspection and quarantine institutions will issue health certificates, which include detailed information such as origin, year, grape variety and filling date. , so that consumers can distinguish whether the wine meets the relevant hygiene standards and whether it is legally imported food.

In order to prevent illegal personnel from forging false inspection and quarantine certificates, AQSIQ has started to use a new version of the inspection and quarantine certificate since 20 10 1, and the new version of the certificate has added a copy prevention function. The background of the certificate is sky blue and contains hidden features. In general, the hidden features are invisible, but the word "copy" will clearly appear on the copy.

Third, look at the label: see if the bottle label is clearly printed and plagiarized. According to China's "Food Safety Law" and "Measures for the Administration of Import and Export Food Labels", there should be Chinese labels and instructions for importing into prepackaged foods.

The contents of the label should not only be completely consistent with the foreign language, but also include the following items: food name, country or region of origin, production date, shelf life, storage guide, name and address of production, packaging, sub-packaging or distribution unit, name and address of general distributor in China, etc. This information must be in Chinese black font. If there is no Chinese label and there is no relevant legal label information, the more you import it. The more likely it is to be false.

4. Look at the bar code: 69 begins with China, 0 is the United States, 3 is French, 7 is Chile, 8 is Spanish and 9 is Australian.

Verb (abbreviation of verb) looks at the unit of measurement: Take France as an example, its unit of measurement is cl, not ml.

Sixth, look at the production date: the method of marking the production date of imported red wine is very special. For example, French red wine is generally labeled as l7296a0611:58+0: 58. L7 stands for 2007, 296 stands for the 296th filling day since New Year's Day in France, A06 stands for the production line number, and 1 1: 58 is the exact filling time of that day.

7. Look at the label on the back: Imported red wine is marked with the original label of the importing country on the front and Chinese on the back.

Eight, look at the tightness of the wine seal: the wine seal on the original imported red wine can be rotated, because the seal is actually a cork.

Nine, look at the wine: look at whether the color of the wine is unnatural, and see if there is unknown suspended matter on the wine (note: a little precipitate at the bottom of the bottle is normal crystal), and whether the color of the wine is turbid.

Ten, wine stopper logo: open the bottle to see if the text on the wooden wine stopper is the same as the text on the bottle label.

Smell: If wine has a choking smell similar to nail polish, it will go bad.

Twelve, taste: drink the first sip of wine, when the wine passes through the throat, the normal wine is smooth, and the problem wine is irritating. After swallowing wine, the smell left in the mouth is chemical or smelly, which is abnormal. Good wine should be refreshing to drink.
