About the Course

This course covers, at a specialist level, the major light (non-sparkling, non-fortified) wines of the world, their regions and methods of production and local trade structures and regulatory issues affecting their production. It relates these factors to the quality and style of the wines not only theoretically but also through expert tasting.

This course has 74 instructional hours including six-plus hours of exams. WSET recommends at least 170 hours of additional, independent study time for this course.

The exam takes place over two days; it involves two one-hour blind wine-tastings of six wines each and two closed-book written exams requiring short-response answers.

International Wine Center offers the D3 course once per year, starting in September. Classes will occur over three blocks of approximately eight weeks each in the Fall, Winter and Spring.  D3 exams will occur in May.

WSET requires that students have studied Level 4, Wine Business D2 before registering for this element.
