WSET LEVEL 4 D1 WINE PRODUCTION COURSE

Your Diploma journey begins with D1 – Wine Production

D1 Wine Production kicks off the WSET Diploma program, and builds a foundation of theory knowledge for future units. This detailed examination of production demonstrates how key decisions in the vineyard and cellar combine to impact a wine’s style, quality, and price.

Prerequisites: A passing score for WSET Level 3 Award in Wines (or Wine & Spirits)

Bundled with $450 WSET New Diploma Candidate Registration

Price includes all study materials, digital textbook access, and exam fee.

We’ll provide a recommended list of wines to purchase for the course. For added convenience, you can also purchase an optional D1 Wine Kit, featuring 12 curated 100ml wine samples from our trusted wine kit partner. The purchase link will be sent in your course registration confirmation email and the kit delivery will be right before your first tasting webinar.

For future course and exam dates, please see the "What's Included" section below.

WSET Diploma New Candidate Registration

The WSET requires all new Level 4 students to register for Diploma Candidacy when enrolling in their first unit, D1 Wine Production. This initial candidate registration enrolls the student as an official WSET Diploma Candidate for a period of 3 years. This is enough time for most students to complete all six units. If a candidate is not able to complete all six units in the initial three years, the WSET will require payment of a candidate renewal fee for an additional three years of eligibility. Any exam passes carry over, so no student ever has to retake any exams they have already passed.

What’s Included

Your D1 registration includes:

Access to WSET's D1 textbook and NVWA's proprietary online classroom, including supplemental learning materials like vocab lists, dozens of mock questions, worksheets, and opportunities for graded answers.
Eight live, instructor-led Zoom sessions, which are also recorded for flexible learning
Twice-weekly open office hours with our Diploma Program Director, Noelle Hale. Bring your questions!
Registration for the next available D1 exam

A wine kit is available as an additional add-on for this course. It includes 12 (100mL) samples of wines that are tasted with an instructor during the final D1 class on Zoom. The goal is to learn how many of the winemaking techniques you learn about in D1 appear in the glass. While calibration is not the focus of the tasting class, completed tasting grids are provided for each wine so you can use them for calibration if you wish.
