Therefore, their per capita output is much higher than ours, and their manors that have been here for decades or hundreds of years have formed a local climate and cultivated regional wine fermentation strains. So their cost is much lower than ours and their quality is much higher than ours. Of course, the situation in each country is different. In Europe, Portuguese products have always been well received for their high quality and low price. Therefore, the quality of a product priced at 100 yuan is equivalent to that of a French product priced at 200 yuan, and is better than a domestic product priced at more than 300 yuan. Wine purchasing knowledge: First of all, you should go to shopping malls, supermarkets, etc. with high reputation to buy well-known brand wines with good quality. The second thing is to look at the label to distinguish between original wine and semi-juice wine. It is impossible and absolutely not allowed to add ingredients such as white sugar or potassium sorbate to wine with an original juice content of 100. It should be said that nothing can be added to full juice wine. If white sugar is added to whole juice wine, its alcohol content will increase; potassium sorbate cannot be added because potassium sorbate is a preservative and a chemical substance. Adding it to whole juice wine will destroy the wine ingredients, thus Affects the quality of wine. If a red wine is labeled as containing whole grape juice, white sugar, and potassium sorbate, it should undoubtedly be a half-juice wine. The third is to look at the appearance. You should choose a wine that has a clear, transparent and shiny appearance, a color consistent with the name of the wine, a natural and pleasing color; a balanced, harmonious and integrated aroma, an elegant and pleasant aroma; a comfortable, pleasant and soft taste, and a full and complete wine body. A wine with a long finish. If it is turbid and dull, the color does not match the name of the wine, there is no natural feeling, the color is bright, there is an obvious sense of artificial coloring, there is a prominent and violent fruit aroma, a prominent alcohol smell, other odors, or there is an odor, prominent odor, and the body of the wine Don’t buy wine that is thin and has no aftertaste. Another way to identify real and fake wine is to add hydrochloric acid and sodium hydroxide to the wine. The color of high-quality wine will become darker when exposed to acid, but the color will return to its original state after adding alkali. Inferior wine will not change color even if acid or alkali is added. If there is no acid or alkali at home, white vinegar and edible alkali can be used instead. Wine does not become more valuable the longer it is stored. Many people have misunderstandings about wine. The biggest cognitive fallacy is the blind worship of wine vintage. Many people believe that vintage is an important criterion for evaluating the quality of wine. They believe that the older the wine, the better. Wine with a long vintage must be a good wine. Not really. Why do most people think that wine lasts longer? There are two basic reasons: one is the misunderstanding of "vintage", and the other is the misunderstanding of people's inertial thinking. Most businesses in the wine industry almost always emphasize that their products have a long history and put the vintage in a prominent position to attract consumers' attention. But many people don’t really understand the value of “vintage” to wine. "Vintage" has special significance in the field of wine. It is related to natural factors such as weather conditions and terroir characteristics of the year, and is a prerequisite for affecting the quality of wine. The criterion for judging the quality of a year is not related to age, but to a series of natural indicators, such as rainfall, sunshine hours, etc. Just as the 2000 vintage was an excellent vintage for wine, it received extremely high scores from wine critic Robert Parker. This vintage of Lafite was even more expensive than the 1991 vintage of Lafite. Another reason may be related to people’s cognitive habits. People will think that time is the best criterion for testing everything. Products that can survive for a long time and withstand the test of time are often good products. This understanding actually ignores the characteristics of wine as a product. Since the promotion of distilled spirits such as foreign wines is stronger than that of wine, the emphasis on wine age in the world of distilled spirits often biases consumers’ perception of wine, believing that wine, like distilled spirits, is better if it is aged longer. It is not tenable to judge wine based solely on its age. In addition to innate conditions such as weather and soil, factors that affect wine quality include the skill of the winemaker and the accuracy of the winemaking process. Therefore, the older the wine, the better. Good wine comes from the perfect combination of heaven, earth and people. Wine has a life process similar to that of human beings, from birth, growth, maturity, decline to death, no matter what kind of wine, this process occurs.Wine is a commodity full of personality. Each type of wine, or even wine produced by each winemaker, has a different growth time. In other words, the suitable drinking time of each wine is different. Some may need to be drunk fresh, and will enter the decline period after this time; some (such as French classified wines) must be stored for a certain period of time. In the mature stage, its characteristics cannot be brought out and its value cannot be reflected at all. How to divide wine? One of the simplest criteria is to divide wine into New World and Old World. The New World refers to countries such as the United States, Australia, New Zealand, South Africa, Chile and Argentina that have only developed the winemaking industry for two to three hundred years. Due to the humid climate, abundant sunshine and unique soil characteristics of the New World, the wines produced in the New World have fresh fruit flavors and high sugar content, so they are not suitable for long-term storage. If the wine is stored for too long, the fruity flavor will be lost, and its outstanding features will disappear. The wines of Jing New World are generally suitable for drinking within 5 years, and during these 5 years, they must be stored at a humidity of 70 and a temperature of about 21°C. Keep it in a cupboard or cellar. The Old World refers to France, Italy, Germany, Spain and other countries with thousands of years of wine-making history. The grapevines planted in its vineyards are relatively old, often decades old. Coupled with the soil characteristics suitable for growing grapes, the wine produced has sufficient tannin, making it inherently resistant to storage. Dispute Resolution Consumers and sellers or producers can negotiate in advance on issues such as whether to compensate, the amount of compensation, or the payment of compensation. If they disagree, they can choose to file a complaint or lawsuit with the industrial and commercial authorities, quality supervision, or consumer rights protection organizations in accordance with the law. . Article 10: Any unit or individual has the right to report violations of this law to the product quality supervision department or other relevant departments. The product quality supervision department and relevant departments shall keep the whistleblowers confidential and reward them in accordance with the provisions of the people's governments of provinces, autonomous regions, and municipalities directly under the Central Government. Therefore, you can complain to the local quality supervision, industry and commerce departments, etc. You can ask for the complaint phone number 114, or 12365 in some areas. Lawyers suggest that you must ask for an invoice when purchasing. At the same time, when purchasing red wine, pay attention to whether it is a registered trademark and the content of the trademark label, including product name, ingredient list, net content, pure juice content, alcohol content, sugar content, factory name, Factory address, production date, shelf life, product standard code, etc. In addition, consumers should try their best to purchase pure juice wines with grape varieties labeled, as the quality of such wines is more guaranteed.
