The Diploma is broken into two Foundation and four Product Knowledge Units taught at various times and locations (including online) over two years. Units D1 and D2 must be taken first. You pay for all other units as you take them, allowing you to spread out the cost of the Diploma. Additionally, we offer payment plans upon request.
The fee for Units D1 also registers you for three years with WSET and grants access our proprietary online learning platform—a unique site with critical study support and special offers. Please note that WSET Diploma Units D3 through D6 are not always taught in numerical order.
D1: Wine Production
Students will understand what the vine requires to produce grapes for wine production and grape growing options. You’ll learn how natural factors in the vineyard influence the vine’s ability to produce grapes for wines of different styles, quality levels and prices, as well as winemaking and post fermentation options. Assessment to pass D1 is a 90-minute short written answer exam.
