Imported wine is not only increasing in quantity, but also needs people to sell it. The entry level of wine sales is relatively low, so graduates of related majors have certain advantages and it is easier to do sales. I have met many of your brothers and sisters, most of whom are engaged in the sales of imported wine industry.
What's the sales salary? The basic salary is several thousand yuan. If you want a high income, it depends on your sales ability. Besides, you are not an extrovert, so it is a bit difficult to make a sales forecast.
There are several suggestions: if you like wine technology, you can learn foreign languages well; If you can master French and Spanish, English is necessary. Then you can do a lot of work. If you are directly employed, you can do the relevant civil work of foreign wineries or associations in China. Or the external work of a wine import company.
If you want to continue to work in wine technology, one is to find some good wineries in China and start from the foundation. Brewing itself is farm work, not high above it. Or you can study abroad or find an opportunity to work in a winery, and then return to China after you have some experience, so the foundation is much higher.
The other is to be a professional sommelier and train lecturers. This requires a relevant certificate and can be taken in the university. Of course, the higher the level, the better English you need.
In short, any line can survive and realize itself. But they all need to work hard and find the right direction.
