Taste red wine. Different grape producing areas, due to different soil and water, climate, temperature and humidity, grape varieties, brewed wine tastes different, but it also meets the needs of people with different tastes. The rise of "new world wines" such as California, Australia, New Zealand and even South Africa just illustrates this point. This is why the label of each bottle of wine should indicate the origin, year and grape variety, not just the brand. For wine, the brand only gives us a strict guarantee of quality. Whether it is our favorite taste or not comes from the details on the label. There may be no difference between the same Nike shoes made in the United States and those made in Thailand, but the same brand of red wine made in Australia and France may taste completely different.

Identification of French wines

The first step is to look at the appearance of the bottle.

? See if the bottle label is clearly printed? Is it fake or copied?

? See if there is anything wrong with the bottle cap. Are there any signs of being opened?

? See if the international bar code on the label on the back of the bottle starts with three words: the French international code is 3.

Step two, look at the wine.

? See if the color of wine is unnatural?

? See if there is any unknown suspended matter on the wine. (Note: A little precipitation at the bottom of the bottle is a normal crystal)

? When the wine goes bad, the color becomes cloudy.

The third step is to look at the logo of the wine stopper.

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

Step four, smell the wine.

? If wine smells like nail polish, it will go bad.

Step five, taste the wine.

? After drinking the first sip of wine, when the wine passes through the throat, the normal wine is smooth, while the problem wine has a stimulating feeling.

? It is not normal for the smell left in the mouth to have a chemical smell or a foul smell after swallowing wine.

? Good wine should be refreshing to drink.

Identification of true and false red wine

The easiest way to identify the authenticity of wine is to take a good quality napkin and pour red wine on it. The red color in the original red wine is a natural pigment with very small particles. The wet stain spread on the napkin is even red with red wine, and there is generally no water stain to spread. Because fake red wine is blended with chemical synthetic pigments such as inkstone red, its pigment particles are relatively large, which will generally precipitate on napkins, and at the same time, there will be water traces spreading outward. You might as well try.

Common sense of wine purchase

You should go to reputable shopping malls, supermarkets and other places to buy well-known brands of wine with good quality.

Look at the label and tell the difference between original juice wine and semi-juice wine. It is impossible and absolutely impossible to add white sugar or potassium sorbate to the wine with the original juice content of 100%. It should be said that you can't add anything to the whole juice. If sugar is added to the whole juice wine, its alcohol content will be improved; Potassium sorbate should not be added, because potassium sorbate is a preservative and a chemical substance. Adding potassium sorbate to whole juice wine will destroy the composition of wine, thus affecting the quality of wine. If a red wine is labeled with whole grape juice, white sugar and potassium sorbate, it should undoubtedly be semi-juice wine.

Look at the appearance. You want to buy a clear, transparent and shiny appearance, with the same color as the wine name and natural and pleasing color; The fragrance is balanced, coordinated and integrated, and the fragrance is elegant and pleasant; Wine with pleasant and soft taste, full body and long aftertaste. Don't buy it, it's cloudy and dull, the color doesn't match the name of the wine, it has no natural feeling, the color is gorgeous, and it has obvious artificial color feeling; It has outstanding and violent fruit fragrance (with essence), outstanding alcohol smell and other peculiar smells; A wine with peculiar smell, outstanding special fragrance, thin body and no aftertaste.

Another way to distinguish between true and false wine is to add hydrochloric acid and sodium hydroxide to the wine. The color of high-quality wine will darken when it meets acid, but it will return to its original state after adding alkali. Bad wine will not change color if it is added with acid and alkali. If there is no acid or alkali at home, you can use white vinegar and edible alkali instead.

Experts suggest that consumers can start from two aspects when purchasing wine:

One is to judge from the content of the label.

The contents of wine labels should be complete and accurate, mainly including the following contents:

1, product name. According to the definition of product, the name should be "wine".

2. alcohol. The alcohol content of wine should not be less than 7%(V/V).

3. Implement standards. The wine standard in China is GB/T 15037.

The second is to judge from the internal quality.

The quality of wine includes hygiene, physico-chemical and sensory, among which sensory index is the most comprehensive and effective index to reflect the quality of wine. The sensory indicators of wine should be reflected in the following three aspects:

1, appearance. The appearance of wine is mostly clear, transparent and shiny, and the color is consistent with the name of the wine.

2. Aroma. Wine is a fermented product, and its aroma should be fruity, fermented and aged. These aromas should be balanced, harmonious, elegant and pleasant.

3. Taste. The taste of wine should be comfortable and pleasant, with delicate and soft aroma and long aftertaste.
