Wine education is pursued for a multitude of reasons, ranging from personal enjoyment to career advancement. Formal wine training can be achieved and applied at a number of levels in a number of arenas. For the ambitious few with their sights set on the highest level of education in the industry, there are two paramount credentials often equated as the MDs and PhDs of the Wine Industry: Master Sommelier and Master of Wine. Both require years and years (and years) of dedication, strategic study, and calculated advancement. Candidates usually require multiple attempts at the exams and many never pass.
