How to distinguish the quality of red wine? Red wine has a long history and produces a variety of red wines. As for the purchase of red wine, we should learn how to distinguish between good and bad. So, how to distinguish the quality of red wine? Let's share it below.

How to tell the quality of red wine 1 How to tell the quality of red wine?

1, look at the wine label

The information of the wine label covers the most, and the quality of this wine can basically be judged by the wine label. You can know the name, origin, year, brewing variety and grade of this wine through the wine label. Through these basic information, we can roughly judge the position and quality of this wine.

2. Look at the awards.

To judge the quality of a wine, in addition to the wine label, you can also refer to whether you won the prize in the international wine competition.

Every wine competition in the world brings together many well-known judges to select excellent wines in a fair and just way, which is not authoritative. The International Wine Competition not only provides an excellent promotion platform for wine merchants, but also provides a reference for wine consumers to buy wine.

3. Look at this bottle

After reading wine labels and awards, you can basically judge the quality of wine, and then looking at the bottle can help you observe and infer the quality of wine. It is unscientific and relatively one-sided to judge the quality of wine only by looking at the bottle body, which may easily lead to the possibility of buying inferior wine.

(1) Depth of bottle bottom: The biggest function of bottle bottom is to accumulate sediment in wine. This is very important for wine farmers who did not have low-temperature crystallization technology in early wine production. Generally speaking, the more wine needs to be stored for a long time, the deeper the concave and convex.

So it is an early habit to distinguish wine according to the depth of the ditch. However, it is relatively impersonal to judge the quality of wine only by the depth of the bottle bottom. If it is a good wine according to the wine label and awards, and the bottom of the bottle is deep, it means that the reception is relatively old, which is indirectly a good wine.

(2) Bottle weight: Take France as an example. In the past, the weight of ordinary meal bottles was about 400g, the AOC of Bordeaux was above 550g, and La Romanee-Conti was about 900g g. Because ordinary table wine is usually drunk quickly, the requirements for wine bottles are not high, while high-grade wine needs to be aged. If the bottle is too light and thin, it will break easily.

But with the development of science and technology and the improvement of environmental awareness, the weight and quality of wine bottles are not the same. However, judging from the wine label and awards, the heavier the bottle, the more guaranteed the quality of the wine.

(3) Wax cap: sealing bottles with wax is a traditional method of sealing wine. There were no heat-shrinkable caps and tin caps before. In order to effectively prevent air from contacting with wine liquid and reduce the speed of wine oxidation, wine producers often seal the bottle with a cork and coat a layer of wax on the bottle mouth. Nowadays, with the development of science and technology, the traditional way of sealing bottles with wax is relatively rare.

Nowadays, wax sealing is often used for wines with very strong aging potential or wines that want to be preserved for a longer period of time. For daily drinking wine, wax sealing is completely unnecessary.

Although wax wine only has a certain effect on those wines with strong aging potential, it is not common to seal wine with wax now. Therefore, under the premise of judging the good quality of wine according to wine labels and awards, the use of wax covers will better highlight the quality of wine.

However, some wine producers also use wax seals to show consumers the retro style of hand-brewed wine, let consumers experience the tradition of wine, or just want to attract consumers on the packaging. If we only rely on wax caps to judge the quality of wine, it is easy to fall into the "foundry trap" of wine producers.

(4) The name or abbreviation of the winery is engraved on the rubber cap: the general rubber cap is often used for general OEM or ordinary table wine, and the name or abbreviation of the winery is not engraved, but it is prestigious. Wineries usually engrave the name of the winery on their own wine rubber caps, so to some extent, the quality of the wine printed with the name or abbreviation of the winery is more guaranteed.

To sum up, although we can roughly judge the quality of wine according to labels, awards and bottles, storage environment and other factors affect the taste of wine. So to really judge the quality of a wine, you must taste it yourself.

How to tell the quality of red wine II. How to tell the quality of a bottle of wine?

With the improvement of people's living standards, wine has gradually entered thousands of households, and more and more people like to drink red wine. However, most consumers lack the relevant knowledge to distinguish between good and bad wine, and often can't enjoy the tip of the tongue pleasure brought by high-quality wine because they can't distinguish between good and bad wine.

Observe the appearance of the bottle

Every wine has a different appearance, and every wine has its own label. The rich information on the label can help us to judge the origin, origin, year, grade and even taste of this wine. Is there anything wrong with the lid of the bottle? If the unopened bottle stopper bulges or there is mucus in the bottle mouth, it means there is something wrong with the quality of the wine.

Is there a Chinese logo on the back of the bottle? All imported food must be labeled in Chinese. If there is no Chinese label, it may be smuggling and the quality cannot be guaranteed. From the international bar code on the label on the back of the bottle, we can see which country it is produced, such as: 3 French origin, 6 China manufacture, 8 Italian origin and 9 Australian origin.

Some French wine bottles have icons with women's heads printed on the lead seals, which prove to be authentic original wine after paying taxes in France. There is also information at the bottom of the bottle. If it is imported from France and other countries, the measuring unit at the bottom of the bottle is 75cl, not 750ml. There is no such unit of measurement as milliliter in France.

There will be a protrusion at the bottom of the wine bottle to store the wine residue precipitated when the wine 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.

Observe the wine body

Is the color of wine unnatural? Usually, the color of wine is ruby red, or clear natural wine color, such as light gold and pink. After the wine body goes bad, it will have a turbid feeling. If the color is unnatural, it will be suspected of blending.

Wine bottle stopper recognition

Open the bottle and see if the words on the cork are the same as those on the bottle label. In France, wine bottles and wine stoppers are special.

Smell the wine

Usually, when you open a bottle of wine, you will smell the aroma of the wine (fruity, even floral). If the wine smells of nail polish or acetic acid, it means that the wine has gone bad.

Observe the hanging wine glass

Pour the wine into a red wine glass, shake it gently, and observe whether the wine body hangs on the glass. If the wine body can't hang a cup, it means that the wine can be blended. The normal wine liquid hangs on the glass wall in a uniform circle, even and meticulous like a "little skirt".

Taste wine

After drinking the first sip of wine, the normal wine is smooth when the wine passes through the throat. If there is a strong sense of irritation, or the smell left in your mouth is chemical, or it stinks, it is not normal.
