This unit focuses on viticulture, vinification, maturation, and bottling. You will learn what the vine requires to produce grapes for wine production, grape growing, winemaking, and post-fermentation options and how this influences style, quality, and price. This unit must be taken before attempting any other Diploma course. This course provides the foundation needed for taking D3, D4, and D5. This unit is assessed by a 90-minute multiple-part open-response exam.

You must have passed the WSET Level 3 exam before registering for the Diploma Program.

The course fee includes WSET’s 3 year registration fee; access to all Diploma study materials in the WSET Online Classroom; the four week course, and the Unit D1 Examination at Capital Wine School.

***Diploma New Candidate Registrations will be submitted to the WSET three weeks before the course begins, or within 72 hours of registration if the course start date is less than three weeks from the date of registration.
