Alcohol-related industries generally include: sales, catering, education/training and production. Among them, alcohol production belongs to technical engineering, and it is generally done by brewing professionals, so there is not much discussion. The rest can be summarized as service and sales according to the nature of their work, which involves 1. knowledge reserve of alcohol; 2. Wine-serving skills; 3. sales skills

and the intersection of these three skills points to the "soul figure" of the wine industry-the sommelier. This means that from sales, catering to training, it is within the necessary ability of the profession of "sommelier", so it is unified here.

The sommelier is a high-end comprehensive skilled person in the wine industry/catering industry, and needs to master all the knowledge and skills related to service/sales/training/drinks and meals. These skills are classified in detail, including comprehensive knowledge and skills such as professional wine service skills, wine matching skills, wine sales skills, staff training, western food etiquette, wine cellar management, wine procurement, wine list design, reception planning, etc. In addition, it is necessary to have a large amount of wine knowledge reserves and excellent wine/spirits/cigars tasting skills. Therefore, the threshold for becoming a sommelier is very high, which is why sommeliers become scarce talents in the market.

In recent years, the number of excellent sommeliers in China has gradually increased. In order to gain recognition from the wine industry and high-end catering industry, there have been national standard sommelier qualification certifications, such as the post certificate of star sommelier in China hotel industry. Personally, I think that the gold content is self-evident whether it is applied to any of the above occupations.
