The WSET Level 4 Diploma in Wines is the WSET’s flagship qualification, designed to prepare those in the trade for senior positions within the wines business. This qualification is also suitable for the dedicated wine enthusiast wishing to build on knowledge gained at Level 3 and acquire further expertise in wine tasting. The course of study will not only develop product knowledge to a specialist level, but will also enable students to acquire skills that will continue to be of use beyond the course. Please note, students must have passed the WSET Level 3 exam in order to register for the Diploma program.

The Diploma in Wine program begins with Unit D1, Wine Production. Every Diploma candidate must take the Unit D1 course and exam before moving on to other Diploma units. The Capital Wine School typically offers the Unit D1 course and exam two or three times each year. Currently scheduled courses and all Diploma units can be found below (click on “Details & Register” for more information on each course).

After taking the Unit D1 exam, candidates should take Unit D2 Wine Business. After Unit D2, candidates may take the remaining units in any order desired, although we recommend taking Unit D3 last, as it is the most difficult unit and there are concepts and skills taught in Units D4 and D5 that will better a candidate’s chance for success in Unit D3.

All exams must be taken in person at the Capital Wine School.
