How to judge the quality of red wine? You may not know that inferior wine is a "wine" made of water+pigment+alcohol+essence. Drinking it will not only cause headaches, abnormal heart rate and even cancer, but also do great harm. So how to judge the quality of red wine?
How to judge the quality of red wine 1 Judging the quality of red wine mainly depends on the color of red wine. The color of red wine can judge the quality of red wine. Generally speaking, the color of red wine is very bright and shiny. If the color of a bottle of wine is very dull, then the red wine is polluted or excessively oxidized.
Six ways to see the quality of red wine
Look at the packaging
Good wine is mostly packaged in dark wine bottles, such as green and brown wine bottles. Its advantage is that it can filter out light waves that have an impact on wine quality, which is beneficial to wine preservation. The darker the bottle color (brownish red), the better the effect. The quality of the wine bottle should be thick and uniform in color, and there should be no patterns, cracks and blisters on the appearance.
Bottle caps are mostly made of cork and metal screw caps, and the bottle caps are tightly sealed. The trademark is clear and complete, and the wine name is outstanding. Consumers can check the logo, alcohol content, sugar and so on when purchasing. High-grade wines are usually covered with a layer of transparent paper to protect the cleanliness of the bottle surface and the integrity of the trademark.
Look at the wine label
The wine label covers a lot of information, and the basic information of wine can be basically judged from the wine label, especially French wine has a long history and a very standardized wine certification system.
Red wine is divided into four grades, namely legally produced wine (AOC), excellent produced wine (VDQS), regional table wine (VDP) and daily table wine (VDT). You can know the name, origin, year, grape variety and grade of this wine through the wine label. Through these basic information, we can roughly judge the quality of this wine.
Look at the place of origin
The smaller the label of origin, the higher the quality. Generally, the quality of village liquor is higher than that of regional liquor, and the quality of regional liquor is higher than that of regional liquor.
If they are of the same AOC grade, but the marked producing areas are Bordeaux, Medoc and pauillac, then the quality of village-level pauillac wine is the highest, and the quality of district-level Bordeaux wine is the most general.
Look at the year
The quality of wine depends three points on technology and seven points on raw materials. Every year, climate, light and rainfall have great influence on the quality of grapes, so the quality of the year is directly related to the quality of wine, especially for a fine wine.
For example, good years in Bordeaux are 20 10, 2009, 2005, 2000, 1996, 1990, 1982. A bottle of 20 10 Lafite Rothschild wine will be better than 20 1 1.
See if there is any precipitation in the wine.
Turn the red wine bottle upside down, tilt it at a certain angle, and look at the bottom of the bottle to see if there are any more sediments and residues. If it is too much, it means there is something wrong with this wine. If there is no or a small amount of transparent precipitate, it is normal (tartaric acid and tartar precipitate will be produced in the long-term fermentation of red wine).
Look at this color.
To judge the quality of red wine, color discrimination can only be used as a reference. For example, the color of new wine is bright, 3-5 years old wine is a little blue and light purple, 5-8 years old wine is brick red, and 8- 10 year old wine is amber.
How to judge the quality of red wine 2 1? 1. Distinguish domestic wine from imported wine: the label on the back (as shown in the figure) starts with the country of origin code, such as domestic bottling 69, US and Canada 0, France 3, Italy 8, Australia 9, etc. My friend bought a bottle of domestic canned wine starting with 69 at a high price. The actual value of this bottle of wine is only a few tens of dollars.
2. Unit of measurement of wine: For example, French-made red wine, the unit of measurement is cl instead of ml.
3. Front and back wine labels: the front of imported wine is the original label of the importing country, and the back is the Chinese back label.
4. Tightness of wine seal: The wine seal on the wine stopper of imported wine can be rotated.
5. Wine color: the color is unnatural and turbid, and the unknown suspended matter is inferior wine.
6. Wine stopper marking: After the wine is opened, observe whether the text on the wine stopper is consistent with the text on the bottle label.
7. Smell: Inferior wine or deteriorated wine has a choking smell similar to nail polish.
8, taste: a high-quality wine, smooth throat, refreshing. On the other hand, inferior wine has throat irritation, chemical smell and foul smell.
9. Edible alkali: When edible alkali is added to the wine, the high-quality wine will change color, but the inferior wine will not change color.
10. Paper towel identification: the first drop of wine is in the center of the paper towel, and the wine is spread evenly without water trace to become real wine, otherwise it is spread unevenly with water trace to become inferior wine.
How to judge the quality of red wine 3. Opinion: the color of wine.
First of all, the color of wine should match the year and grape variety. Different grape varieties will certainly produce different colors of red wine. In addition, the older the year, the lighter the color of red wine will be, from the earliest purple to orange. In this module, the perfect score is 5. Due to the application of modern technology, ordinary wine can get 4 points or even 5 points.
You can preliminarily judge the quality of a wine from its color. Dark wine is generally not bad, and dark wine is definitely not good wine. In addition, observing the color of wine is the most effective method to judge the year at present.
For example, a red wine that is more than 3 years old is still very bright in color, so there is a problem. In short, remember that the older the year, the darker the color and the more prominent the yellow tone.
From left to right, the years are getting older and older.
In addition, the method of dripping wine on a paper towel and judging the authenticity of wine by observing the diffusion of pigment should not be used again in the future. It's really useless to expose your identity as a small white wine, but it will make others more calm and pit you! Think about it, if it were so easy to judge whether it is true or not, there wouldn't be so many fake wines!
Second, the smell: the aroma of wine
The aroma of red wine requires purity, fragrance and durability. In this module, the perfect score set by Parker is 15. Pure aroma means that the aroma of red wine must conform to the characteristics of grape varieties, such as the green taste of New World Cabernet Sauvignon and the gasoline smell of Riesling.
In other words, this red wine is made from Cabernet Sauvignon, so it must have the proper aroma of Cabernet Sauvignon, otherwise the aroma will be impure. When you are blind, you can also judge the grape variety of red wine by its aroma.
Wen Xiang
Pure, just for fragrance. Basic requirements, aroma (rich and pleasant aroma), lasting and changeable aroma is essential for a good wine. For small white wine, it is difficult to remember the special aroma of each grape. So how to judge?
In fact, it can be simplified. Just remember that no matter what the aroma of this red wine is, at least you should have the desire to smell it. That smelly and pungent wine is either of poor quality or bad.
Third, products: flavor and aftertaste.
After reading and smelling, the next step is to drink. After all, wine is for drinking. Parker gave this module a perfect score of 20. It was evaluated from four dimensions: taste balance, complexity, layering and aftertaste.
Balance refers to the perfect combination of acid, tannin, alcohol and sugar. After careful tasting, you can drink sour taste, sweet taste, astringent taste and the stimulation of alcohol, but you won't feel that one taste is particularly prominent, so as to achieve a balance in taste.
Complex refers to the rich taste of red wine, which combines a variety of flavors. Especially the red wine aged in oak barrels will evolve into vanilla, cigar, cigarette, coffee, leather and other flavors.
For a good wine, layering is a must. A new wine can be toasted without layering, but a good old wine must have a rich layering. So what is stratification?
For example, if you open a bottle of Lafite, at first it gives you a strong berry flavor. With the passage of time, the flavors of tobacco and cedar gradually emerged, and finally the flavor gradually matured, and the flavors of cream and coffee came to the nose. Like an onion, peeled off layer by layer, this is the layering of red wine!
Fourth, the aging potential
As the saying goes, the older the wine, the more fragrant it is. Red wine is no exception, although the alcohol content is only a dozen degrees, and red wine drunk by the elderly over twenty or thirty years can be seen everywhere. Only old red wine will taste mellow. For the module of aging potential, Parker set a perfect score of 10.
The so-called aging potential not only refers to how long the red wine will not go bad, but also includes the time to make the red wine reach its best state. For example, a certain red wine reached the best drinking period when it was aged at 10- 15. After this time, the quality of the wine will decline, so the aging potential of this wine is 10- 15.
Most red wines on the market have no aging potential, which is the patent of high-end red wines. For most red wines with 100 yuan, the module of aging potential can only get 2-4 points.
grade
According to Parker's scoring system, the basic score of all red wines is 50 points, plus the scores of the above four modules, which is the total score of this wine. According to the total score, red wine is divided into five grades.
AAA: 96- 100 points-top wine (exotic)
AA: 90-95 points-outstanding wine.
A: 80-89 points-above average.
B: 70-79-average.
C:60-69- below average.
D: 50-59 points-inferior products (unacceptable)
Quantify the quality of red wine by score. The wine tasting, which was quite mysterious, became less empty. For beginners, it is really difficult to accurately evaluate the score of a red wine, but at least you have mastered a method of how to evaluate it.
For wine lovers and related people, this is indeed an effective method, at least allowing you to systematically judge a red wine!
