A wine manager usually works in the hospitality industry. In this career, your duties include acquiring wine and spirits to serve in a wine bar, winery, restaurant, hotel, or another venue. You are responsible for managing the wine stock and overseeing wine service to the customer. Wine marketing managers, on the other hand, work on the sales side of the industry. In this position, your responsibilities include introducing your employer’s product to a potential buyer and, sometimes, consulting on items such as label and bottle design.
