Red wine is the general name of wine, which can be divided into three categories: red wine, white wine and pink wine. With the improvement of people's living standards, red wine has become an indispensable drink in people's lives, so choosing red wine has become a question that everyone wants to know. So how to choose red wine? Red wine 1 depending on the origin of wine, the sources of red wine are generally divided into "old world red wine" and "new world red wine". Old world red wine refers to some European countries, such as France, Italy, Spain and Germany. It is relatively expensive. New World Red Wine refers to the United States, Australia, Chile, New Zealand, Argentina and other countries. The old world red wine was influenced by the temperature and environment of that year, and the climate of new world red wine was more suitable. However, the grape cultivation technology and wine-making technology of old world red wine are slightly better. 2 According to the different grades of wine, some countries will divide red wine into four grades. For example, France divides red wine into four grades. The best grade is the wine from the legal producing area, called AOC for short, and the bottle body will have the title+the name of the producing area+the logo of the controlled person. The second grade is excellent regional table wine, referred to as VDQS for short, and the bottle body will have the title+the name of the place of origin+the logo of +Qualite Superior. The third level is regional table wine, called VINDEPAYS in French, and the name of VindePays+ producing area will be marked on the bottle. The lowest level is the four-level daily table wine, which is called VindeTable in French, and the wine bottle will have the VINDETABLE logo. The classification of Italy is also four levels, and the highest level is DOCG, which means to ensure the legal regional level. The second grade is DOC, which means wine from legal producing areas. The third level is IGT, which means the level of local food and wine. Level 4 is VDT, which means ordinary table wine. Looking at the manor where wine comes from depends not only on the source of red wine, but also on the manor where red wine is produced. For example, there are more than 9,000 wineries in Bordeaux, France, with uneven quality. Famous wine estates include ChateauLafiteRothschild in Lafite Village, ChateauLatour in Latu Village, ChateauMargaux in Magao Village, ChateauMoutonRothschild in Mu Tong Village, Petrus in Bertus Village, ChateauAusone in Aosong Village and ChateauChBlanc in Baima Village. 4 Looking at the year of red wine, even if it is the same winery and the same brand, there are differences in red wine every year, depending on the rainfall, temperature and illumination of that year. Take Bordeaux 1995 as an example. This summer, the temperature is high and slightly dry, and the grapes are growing well. In addition, the alternation of dry and hot days in 10 and some humid weather provide good conditions for the growth of expensive rot, so this year's red wine is of high quality. 5 see if red wine has the ability to age. More than 95% of red wine on the market does not have the ability to age. Those wines that don't have the ability to age are not preserved as long as possible. The best drinking period depends on their storage environment, grapes and brewing technology. But some red wines have the ability to age and can be stored for decades or even hundreds of years. The aging ability of red wine mainly depends on the strength of tannic acid contained in the wine and the types of grapes. For example, Cabernet Sauvignon is more suitable for making aged wine. There is a way to identify whether a wine can be aged, that is, buy more than a dozen bottles of the same wine, open a bottle every six months and taste it. If its internal structure has not changed much in two or three years, it means that it can be put for a longer time. 6 Looking at the date of red wine, the shelf life of red wine is generally ten years, but it is best to drink it within five years, because red wine has a decline period, and the longer it is left, the worse its taste (except for red wine with aging ability). It's best to drink at its peak, but it's not easy to grasp at the peak, depending on various analyses. Some red wines are marked with red wine year, such as 2005 dry red, which means that they were produced in 2005. No matter when you bought it, the shelf life should start from 2005. 7 Look at the label of red wine, which will clearly indicate the address, factory name, shelf life, alcohol content, product type, raw materials and so on. Consumers should choose according to their own needs. 8 Look at the types of red wine. There are several ways to classify red wine. I won't introduce them one by one here, but mainly introduce the method of classification according to sugar content. Red wine is divided into dry wine, semi-dry wine, semi-sweet wine and sweet wine according to sugar content. When the sugar content in wine is less than 4 grams, it is dry wine, and the sweetness is not felt at the entrance, such as dry white wine and dry red wine. When the sugar content is 4-12g, it is a semi-dry wine with a slightly sweet taste, such as semi-dry red wine, semi-dry white wine and semi-dry peach blossom wine. Semi-sweet wine, on the other hand, contains 12-50g of sugar, which is sweet at the mouth. Sweet wine contains more than 50 grams of sugar and has obvious sweetness at the entrance. For the selection of red wine, we should start from the above points, so that everyone can buy good quality red wine and good taste red wine.
