The foreign wine quality grades are mainly divided into two categories, one is the old world model represented by France, and the other is the new world model represented by the United States.

French wine quality is divided into four grades, the highest is named wine AOC controlled by legal origin, the second is high-quality wine VDQS from excellent producing areas, the third is regional table wine VindePays, and the fourth is daily table wine VindeTable. The principle of French wine quality grading system has been implemented all over the world, but each country is different according to its own situation. The wine of the old world basically adopted the French model. Most of the new world of wine is also named after the place of origin, but some countries only use the name of place of origin as a geographical indication for trademark control. Everything is based on the principle of brewing good wine and implementing wine quality classification.

France, Italy, Spain and other countries in the old world have such detailed laws and regulations because they all have a long history of grape cultivation and wine brewing. What they do is to sum up the tradition, experience and inheritance, standardize them and form clear systems and regulations.

A new world country like America is not as rich in heritage as an old world country like France. Most new wine worlds are also named after their places of origin. On the basis of the concept of origin, according to the actual situation of wine development in China, the origin system that meets its own needs was formulated. For example, in the United States, in order for a region to qualify for AVA, growers or wine producers should submit an application to BATF (American Bureau of Alcohol, Tobacco and Firearms). The application should explain: why and how the named area is used as a separate grape growing area; How to distinguish it from the surrounding land. Usually, the application should be illustrated by factors such as history, climate, soil and water quantity. Like AVA, there is no consensus on grape varieties and planting methods. In Australia, only the basic wine regulations, such as 95% grapes from the same year, can indicate the year on the wine label; Wine with grape as its product name may contain more than 80% grape varieties, but the origin of grapes, the most basic condition for European wine naming, has not become its naming rule. Generally speaking, the wine classification system in the new world is not as strict or even harsh as that in the old world.

Classification of Austrian wines

Since the mid-1980s, Austria has gradually established a set of detailed, strict and reliable regulations on grape cultivation and wine brewing. Austrian wine law was established on the basis of European wine law, but Austria still retains the most stringent laws and regulations unique to its own country and even the world, and has strict requirements on the quality of wine. The year of grape picking, the name of the manor or village that produces grapes, the category of grapes, the taste of wine, quality grade, maturity of grapes, official inspection number, etc. It should be indicated on the packaging of wine.

In terms of quality, Austria divides wine into three grades and six sub-grades: table wine, high-quality wine and gourmet wine. In the classification of different grades, the content of grape juice
