The importance that gastronomy and wine have gained today has led to reassess its service and management. They are key points that imply the professionalization and training of all the staff involved. Just as chefs create original dishes, beverages are the domain of sommeliers. They are in charge of proposing an attractive offer that enhances the menu and meets guests’ expectations. Sommeliers are also responsible for its management in optimal conditions, as well as for advising and serving guests for them to have an unforgettable and pleasant experience. The other side of their service is to generate income from sales and build customer loyalty through careful attention and advice.
