What participants will experience
Each session, participants taste 11 glasses of the same base wine. Ten glasses each contain a single flavour compound, while one glass serves as an unchanged reference wine.

Each flavour is accompanied by an explanation of its origins during viticulture or winemaking. Participants then put their skills to the test in a blind tasting exercise before finishing with a blending activity, recreating common wine styles.

Participants receive a certificate of attendance upon completion of the course.

Who is this course for
Wine students, sommeliers, winemakers, other wine professionals (retailers, importers, educators)

Our teaching method

We add aroma compounds to wine, to create benchmark teaching samples.

During our courses, you will taste 11 glasses of the same neutral wine. 1 of those is kept unchanged as a reference, the remaining 10 each have a single aroma compound added.

This allows practicing identification of common wine aromas and faults one by one.

Swééét experiences

I had the pleasure of working with Sietze on several wine tasting workshops aimed at educating Turkish wine enthusiasts, and the experience left a lasting impression on me. Together, we organized and delivered multiple highly successful sessions that were consistently well received by participants. His exceptional attention to detail and ability to structure each session so that both newcomers and more experienced attendees walked away having learned something new were extremely useful and important. His depth of knowledge about wine is genuinely impressive, and he has a rare talent for translating that expertise into engaging, accessible content for audiences of all levels. Sietze is also an outstanding communicator. He has a natural ability to connect with people, read the room, and adjust his delivery to keep audiences engaged throughout. Beyond his technical skills, he’s simply a pleasure to collaborate with. He is reliable, organized, and always bringing a positive, professional energy to every project.

The Wine Flavour Compounds Seminar has become a valuable addition to the Genius in Gastronomy educational programme. By combining flavour science with practical sensory analysis, it offers wine professionals a unique learning experience that complements traditional wine education. We are proud to have Sietze as one of our international educators and look forward to continuing this successful collaboration for many years to come!

Sietze’s aroma compounds events are some of the most popular events we run at WSET School London. They sell out in record time and get excellent feedback every time we have hosted them. Sietze delivers well-prepared tastings that explore highly technical information whilst creating an approachable and inclusive atmosphere. The formats he has developed are well-researched and thoroughly tested, resulting in smoothly run sessions. Sietze’s area of expertise is becoming increasingly important to wine enthusiasts and professionals, and I couldn’t imagine somebody better to deliver them.
