Sommelier · From cupbearers who tasted a king's wine to blind-tasting floor professionals: how the sommelier turned pouring into one of hospitality's most exacting crafts.
There is no legally required route, which makes the real one easy to miss: nearly every working sommelier starts as a server, commis or barback on a floor with a wine program, and studies upward from there. The certificates that dominate the conversation — the Court of Master Sommeliers ladder, the WSET levels, France's state diploma, Japan's J.S.A. exams — are voluntary everywhere, but they have become the trade's shared language, and past a certain level of restaurant they function as expected currency.
What the exams cannot substitute for is service itself. Every serious credential in the trade examines live service under pressure — carrying, decanting, recovering from a planted error — precisely because the job is performed in front of the customer. The gate at each stage is therefore double: a written or tasted exam, and a restaurant willing to trust you with its list, its guests and its money.
A first job as server, commis sommelier or barback in a restaurant that actually sells wine. Learning carriage, table order and the rhythm of service matters more at this stage than knowing appellations; palates can be trained later, service instincts are slow to retrofit.
The filterGetting hired onto a floor with a real wine program — and being kept: hospitality attrition does most of the trade's first filtering.
First structured study: WSET Level 2–3, the CMS Introductory course, or a national equivalent. The world's wine map — regions, grapes, laws, styles — gets installed here, usually on flashcards between shifts, alongside first disciplined blind tasting.
The filterFirst written and tasted exams; WSET Level 3 and CMS Introductory pass most prepared candidates but fail the unprepared without apology.
The CMS Certified exam, France's Mention Complémentaire Sommellerie, or Japan's J.S.A. Sommelier credential mark the move from server-who-studies to sommelier: a first list to help manage, by-the-glass programs to run, and nightly floor service in the title role.
The filterA practical service examination — open, decant and serve under examiners' eyes — plus theory and tasting; Japan's J.S.A. additionally requires three years of trade experience before candidates may even sit.
The CMS Advanced exam or the WSET Level 4 Diploma — a two-year, six-unit program — separate career sommeliers from the certified. Blind tasting sharpens from party trick to method, and study groups become the trade's real graduate school.
The filterCMS Advanced historically passes roughly a quarter to a third of each sitting; the WSET Diploma's fortified and sparkling units are its notorious gatekeepers.
Running the program: writing and pricing the list, negotiating allocations with importers, managing inventory that can exceed the kitchen's entire equipment budget, hiring and training a team, and owning the beverage P&L that often decides whether the restaurant is profitable.
The filterThe market itself — an owner willing to trust you with six or seven figures of stock, judged on sales history, palate and the loyalty of your regulars.
The Master Sommelier diploma, the Master of Wine, or the competition circuit ending at the ASI's Best Sommelier of the World. All are optional; all are pursued anyway, because at the top of a credential-free trade, the hardest voluntary exams became the summit by consensus.
The filterThe MS exam's three sections — theory, service, blind tasting — each failable and retaken over years; around 270 people have passed since 1969, with per-attempt pass rates under ten percent.
The certificates themselves are the cheap part: CMS stages run a few hundred to around a thousand dollars each, and the full WSET Diploma costs roughly £4,000–£6,000 in London (2024). France's apprenticeship-based MC is effectively free and paid. The real money is liquid: serious blind-tasting practice burns through benchmark bottles, and Master Sommelier candidates routinely describe five-figure cumulative spending on tasting groups, travel and retakes across their attempt years.
Hotel and restaurant schools from Lausanne to Cornell teach service, beverage cost control and floor management directly, and their internship pipelines place graduates into the hotels and starred restaurants where sommelier careers actually start.
Degrees from institutions like Geisenheim, Bordeaux or Davis produce sommeliers who can argue fermentation and rootstock with winemakers — useful authority when buying, and the most common academic background among somms who cross into winemaking later.
Wine law, labels and producer relationships run through European languages, and international guests expect service in their own. Many of the trade's global careers — hotel groups, airlines, cruise lines — shortlist on languages before wine knowledge.
A serious wine program is a six- or seven-figure retail operation inside a restaurant: margin architecture, inventory turnover, supplier negotiation. Wine directors with commercial training run programs that survive; romantics run programs that get cut.
Cooking school builds the flavor vocabulary that pairing depends on and earns credibility with chefs, the sommelier's most important internal ally. A meaningful share of sommeliers, including several world champions, entered the trade through kitchens.
The examining body founded in London in 1977, running the four-stage ladder from Introductory to the Master Sommelier diploma first examined in 1969; its American chapter examines across the western hemisphere.
Flagship classroom of the Wine & Spirit Education Trust, founded 1969; the WSET's four levels are taught in more than 70 countries and examined roughly a hundred thousand candidates a year in the mid-2020s.
A dedicated wine university housed in a medieval castle in the Rhône since 1978, training sommeliers, tasters and wine-trade professionals on French soil where the appellation system was invented.
Bordeaux's sommelier school, preparing candidates for France's state Mention Complémentaire Sommellerie and international careers, with the Gironde's châteaux as its teaching cellar.
Founded in 1969 and now among the world's largest sommelier bodies, its tiered J.S.A. examinations — badge pins worn like military rank in Japanese dining rooms — certify thousands of professionals across Asia's most mature wine-service culture.
South Africa's principal wine school since 1979, feeding sommeliers into Cape Town's restaurant scene and the Cape Winelands' cellar doors, with the southern hemisphere's oldest fine-wine industry as its campus.
Perhaps the world's most exclusive wine school: a single invitation-only week founded in 2001 by Len Evans, admitting about a dozen scholars a year to blind-taste the world's benchmark bottles under Australia's senior judges.
Teaching viticulture and oenology on the Rheingau's slopes since 1872; its science-first graduates populate German-speaking Europe's sommelleries, wine estates and the international wine trade.
The trade's most famous credential: an oral theory exam, a live service exam and a six-wine blind tasting, each failable separately and retaken over years. First examined in London in 1969; roughly 270 people have ever held the title, and per-attempt pass rates run under ten percent.
The Wine & Spirit Education Trust's highest award: a two-year, six-unit program covering viticulture, vinification and the global trade, examined by essay and blind tasting. Less service-focused than the CMS ladder, it is the standard prerequisite for attempting the Master of Wine.
France's state vocational sommelier diploma: a one-year program after a hospitality qualification, mixing classroom, cellar and paid restaurant apprenticeship, examined by the national education ministry. The standard credential on French floors, and effectively free through the apprenticeship system.
The Japan Sommelier Association's professional certification, open only to candidates with at least three years of drinks-service experience and examined on theory, tasting and service. Its grape-cluster pin badge is instantly read in Japanese dining rooms; a senior Sommelier Excellence tier crowns the system.
Plenty of respected wine directors hold no certificate at all: they rose commis to chef sommelier inside great restaurant brigades, learned by tasting with importers and inventory-counting at midnight, and let their lists argue for them. In France and Italy especially, house training and competition results still outrank diplomas.
Retail shops, importers, distributors and winery tasting rooms teach the same product knowledge from the selling side, and the crossover into restaurant sommellerie — or straight into a wine-director role — is common in the US, UK and Australia. Buying experience and supplier relationships transfer; only the service craft has to be learned on the floor.
