Program of Study
Years of Study
D1 & D2 must be studied at the beginning of your Diploma program. The knowledge gained in these units will be used in the Product Knowledge Units.
You will undertake a detailed theoretical study of viticulture, vinification, maturation, treatments, and packaging of wine. This unit is the first unit you will complete, as it builds a foundational level of theory knowledge needed for the study of D3, D4, D5, & D6. This unit is assessed by a multiple-part open-response exam.
D2 Wine Business
You will develop and hone your research skills to study the local & global drinks markets and the marketing of alcoholic beverages. Unit 1 (D2) is assessed via a multiple-part open-response exam.

D6 Independent Research
You will research a specified wine-related subject, demonstrating your knowledge and understanding of the topic using relevant source material to develop ideas and arguments to reach informed conclusions. The research assignment is a 3,000 word paper. There are two topics released each year from which you can choose to research, with respective submission dates in January and July.
The WSET intends for the Diploma primarily to be a self-study educational program. Students will complete a large portion of their studies outside of the classroom. Courses for each unit give the student the opportunity to interact with industry experts and their peers to bolster their personal studies. Students have the choice to complete each individual unit as an in-person course, an online course, or a combination of both.
The in-person course days, held in Napa, are intensive sessions that are a combination of lecture, discussion, group activities, and tasting practice, led by Napa Valley Wine Academy’s expert instructors. Courses for each unit range in length from 2-8 days.
In the online course, students work on weekly activities, individually or in groups, to guide their theory study, as well as submit tasting notes for grading. Instructors for the online course are the WSET’s own instructors. Units range in length from 5-28 weeks, depending on the individual unit.
