How the WSET Level 4 diploma works
The Diploma has six units. D1 must be taken first, followed by D2. Once you have taken the D1 and D2 exams (you don’t need to have your results back), you can take the other units in any order.
The six units of the WSET Level 4 Diploma
The WSET Level 4 Diploma in Wines is made up of six units. Five are assessed by examination and one by a 3,000-word research paper. D1 must be sat before you progress to any other unit. D3 alone carries half the total study weighting of the qualification. Registration is valid for three years from enrolment.
D1 — Wine Production (20% of the Diploma)
D1 examines how decisions in the vineyard and the winery shape a wine's style, quality and price. It is the entry point to the Diploma and must be taken first. Assessed by a 90-minute open-response paper. Requires a pass in the WSET Level 3 Award in Wines or the Level 3 Award in Wines & Spirits. See D1 dates and pricing →
D2 — Wine Business (10% of the Diploma)
D2 covers the commercial side of wine: pricing, the businesses engaged in production and distribution, routes to market, and marketing. Assessed by a 60-minute open-response paper. Requires D1. See D2 dates and pricing →
D3 — Wines of the World (50% of the Diploma)
D3 is the largest unit in the Diploma, carrying half the total study weighting. It covers the still wines of France, Germany, Austria, Hungary, Greece, Italy, Spain, Portugal, the USA, Canada, Chile, Argentina, South Africa, Australia, New Zealand and China. Assessed over two consecutive days: a two-part theory examination of 3 hours 20 minutes, then a blind tasting of 12 wines across two papers totalling 3 hours. Requires D1 and D2. See D3 dates and pricing → · Practise with the D3 Mock Exam →
D4 — Sparkling Wines (5% of the Diploma)
D4 covers the sparkling wines of France, Germany, Italy, Spain, the UK, the USA, South America, South Africa, Australia and New Zealand. Assessed by a single 90-minute paper combining open-response questions with a blind tasting of three sparkling wines. Requires D1 and D2. See D4 dates and pricing →
D5 — Fortified Wines (5% of the Diploma)
D5 covers Sherry, Port, Madeira, Vins Doux Naturels and Rutherglen Muscat. Assessed by a single 90-minute paper combining open-response questions with a blind tasting of three fortified wines. Requires D1 and D2. See D5 dates and pricing →
D6 — Independent Research Assignment (10% of the Diploma)
D6 is a 3,000-word research paper on a topic set by WSET. Two topic briefs are released each year on 1 August, with deadlines the following 31 January and 31 July. There are no scheduled classes; Napa Valley Wine Academy provides an online resource module including distinction-level example papers. See D6 topics and pricing →
How much does the WSET Diploma cost?
Tuition across all six units at Napa Valley Wine Academy is $7,135, paid unit by unit as you progress rather than upfront. Each unit price includes tuition, study materials, digital textbook access and your examination fee. Your D1 enrolment includes the one-time WSET New Diploma Candidate Registration.

WSET specifies a Total Qualification Time of 500 hours for the Level 4 Diploma: 128 guided learning hours, of which 11 hours and 50 minutes are examinations, plus a minimum of 372 hours of private study. Most candidates complete the Diploma in 18 months to three years.
