How to see the quality of red wine? 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.
