WSET vs Court of Master Sommeliers (CMS): Which Wine Certification Is Right for You?
Comparing the two most prestigious wine certifications: WSET and the Court of Master Sommeliers. Different approaches, different strengths, different career paths.
If you’re serious about wine credentials, two names dominate the conversation: WSET (the Wine & Spirit Education Trust) and CMS (the Court of Master Sommeliers). Both are prestigious. Both are demanding. But they’re designed for different people with different goals.
Here’s how they compare.
The Fundamental Difference
WSET is academic. It teaches you about wine — how it’s made, where it comes from, why it tastes the way it does. The emphasis is on knowledge, analysis, and understanding the global wine landscape.
CMS is practical. It teaches you to serve wine — how to recommend, pair, present, and manage a wine program. The emphasis is on service, blind tasting, and restaurant operations.
Think of it this way: WSET trains wine experts. CMS trains sommeliers.
Structure Comparison
WSET Levels
| Level | Focus | Duration | Cost |
|---|---|---|---|
| Level 1 | Introduction to wine | 1 day | $300-400 |
| Level 2 | Grape varieties, regions, winemaking | 3-5 days | $600-900 |
| Level 3 | Advanced theory + analytical tasting | 5-8 days | $800-1,400 |
| Level 4 | Diploma (near-MW level) | 2-3 years | $5,000-8,000 |
CMS Levels
| Level | Focus | Duration | Cost |
|---|---|---|---|
| Introductory | Wine basics + service fundamentals | 1-2 days | $500-600 |
| Certified | Theory + blind tasting + service exam | Self-study + exam | $500-600 |
| Advanced | Deep theory + advanced tasting + service | Self-study + exam | $800-1,000 |
| Master | The ultimate sommelier qualification | Years of preparation | $1,000+ |
Exam Format
WSET Exams
- Theory: Written exam with short-answer and essay questions
- Tasting: Structured analytical tasting using the SAT methodology — describe wines and assess quality (Level 3+)
- No service component: You’re never asked to open a bottle or interact with “guests”
CMS Exams
- Theory: Oral examination — examiners ask questions and you answer verbally
- Tasting: Blind tasting — identify wines by grape, region, and vintage without seeing the label
- Service: Live demonstration — open and serve wine to examiners playing the role of restaurant guests
The CMS format is more performance-based and stressful. WSET is more academic and allows for contemplation.
Career Applications

Which Should You Start With?
Start with WSET if you:
- Want broad wine knowledge first
- Prefer academic learning to performance-based testing
- Work (or want to work) outside restaurants
- Are interested in wine from a production, business, or analytical perspective
- Want a globally recognized credential
- Plan to study at your own pace with supplementary tools like Sommo’s WSET prep
Start with CMS if you:
- Currently work in fine dining or aspire to
- Want to develop blind tasting ability specifically
- Thrive under performance pressure
- Are focused on the restaurant/hospitality career path
- Value the mentorship culture of the CMS community
- Are based in the US where CMS carries particular weight
The “Do Both” Path
Many top wine professionals hold both certifications. A common progression:
- WSET Level 2 — Build foundational knowledge (~6 months)
- CMS Introductory — Validate basics + start service training (~3 months)
- WSET Level 3 — Deepen theory and analytical tasting (~12 months)
- CMS Certified Sommelier — Combine knowledge with service skills (~12 months)
- Choose your track: WSET Level 4 Diploma OR CMS Advanced, depending on career direction
This path gives you the best of both worlds: WSET’s comprehensive knowledge base and CMS’s practical service skills.
Preparing for Either Certification
Regardless of which path you choose, the preparation strategies overlap:
Build systematic tasting skills: Both certifications require analytical tasting. Sommo’s Tasting Note Wizard trains you in the SAT methodology used by both WSET and CMS.
Memorize efficiently: Both require retaining vast amounts of factual information. Spaced repetition is the most effective method for this.
Taste widely: Both reward experience with diverse wine styles. Use Sommo’s wine scanner and journal to learn from every bottle you encounter.
Know the regions: Both test geographic knowledge extensively. Sommo’s interactive wine map and region guides provide visual, memorable study aids.
The Bottom Line
There’s no wrong choice between WSET and CMS. Both are rigorous, respected, and valuable. The right certification is the one aligned with your career path and learning style.
If you’re unsure, start with WSET Level 2. It provides comprehensive foundational knowledge that’s useful regardless of where your wine journey leads — and it makes CMS preparation easier if you decide to pursue both.
