Where can I find a good wine blender?

It depends on your product positioning. Generally, the styles and techniques of winemakers in North and South are different. There are not many qualified sommeliers, and the intermediary talent market is not satisfied. General wineries will not easily change winemakers for the sake of product stability. You can contact friends in the wine industry for help. If the scale is not large, you can consider finding a part-time job and visit the liquor association if necessary.
