Service Exam Components — Tableside Service, Wine Recommendations, and Decanting Demonstration

Tableside service, wine recommendations from a list, and decanting demonstrations are the three practical service competencies assessed within Court of Master Sommeliers (CMS) examinations. These components appear starting at the Certified Sommelier level and increase in complexity and expectation through the Advanced and Master Sommelier Diploma examinations. They are not components of WSET qualifications, which are structured around written theory and blind tasting assessment only. The CMS framework reflects the organization's mission to certify professionals who can perform flawlessly in a real restaurant environment, not merely recite wine knowledge.

• CMS is a four-level certification program: Introductory, Certified Sommelier, Advanced Sommelier, and Master Sommelier Diploma
• Practical service components first appear at the Certified Sommelier level, the second tier of the CMS program
• WSET Level 3 Award in Wines assesses only theory and blind tasting; no practical service module exists at any WSET level
• CMS service standards are published by the Court of Master Sommeliers, Americas and serve as the official benchmark for all examinations

The tableside service examination simulates a real restaurant environment, with Master Sommeliers acting as the dining guests. Candidates must demonstrate gracious carriage, sound service mechanics, and active salesmanship throughout. The CMS service standards specify that beverage service is always performed to the right of the guest, the wine list is presented and the order taken from the host's right, and the order is verbally repeated back to confirm the vintage and producer. After the host approves the taste, service proceeds clockwise around the table, beginning with any guest of honor. The bottle is wiped with a clean serviette after each pour to prevent drips, and the bottle is placed on an underliner or in an ice bucket within reach of the host.

• Glassware is placed to the right of each guest prior to service, brought to the table on a tray
• The sommelier presents the bottle label-side up, verbally confirming the wine name and vintage before opening
• Service moves clockwise from the host after the approval taste; a fresh glass is brought to the host if a second bottle of the same wine is ordered
• Candidates must be prepared to open still wines, sparkling wines, and wines requiring decanting without disturbing the table or the guests

Wine recommendation ability is woven throughout the CMS service examination rather than existing as a fully separate exercise. Candidates may be asked to recommend wines to accompany food from a menu, propose a beverage to pair with a specific dish, evaluate the strengths of a pairing, or discuss food and wine pairing options with guests. The CMS service standards emphasize that the sommelier must be prepared to answer questions on the style, history, quality, vintages, and food pairings for every wine on the list. Recommendations must balance guest preference with commercial awareness, and candidates are expected to explain their choices clearly, pivoting gracefully if a guest's needs change mid-service.

• Candidates may be asked to propose beverage pairings for specific dishes, assess pairing suitability, and explain the reasoning behind any recommendation
• The CMS frames salesmanship as an essential element of service, not a secondary concern; active and appropriate recommendations are expected throughout
• Business of the Sommelier, including cost awareness and wine list management, is also tested as part of the Certified Sommelier theory examination
• At the Advanced and Master levels, expectations for pairing sophistication and verbal articulation increase substantially

Decanting is a formally assessed skill within CMS examinations and requires both physical precision and verbal explanation of the decision to decant. The CMS-A service standards specify that a gueridon is indispensable for decanting and must be fully set with all materials before being rolled tableside, preferably to the host's right. The bottle is placed carefully in a decanting basket lined with a clean serviette, the candle is lit away from the table, and the wine is poured into the decanter in a single, smooth motion while watching for sediment at the shoulder of the bottle through the light source. The sommelier should assess the specific needs of the wine and confirm with the guest before proceeding.

• The decanter is never allowed to touch the bottle during pouring; the pour must be slow, smooth, and uninterrupted to avoid disturbing sediment
• Pouring stops as soon as fine sediment reaches the shoulder of the bottle; unless the guest specifies otherwise, only the clear wine is served
• After decanting, the sommelier pours the host a 1 to 1.5 ounce taste from the decanter and waits for approval before serving the table
• Splash decanting, used for aeration of young wines, is a recognized technique but is not appropriate for older or more delicate wines or when removing sediment

The three practical service components ensure that CMS certification signals genuine professional readiness in fine dining and hospitality environments where technical wine knowledge alone is insufficient. The CMS-A describes the ultimate goal of these standards as reading the table's needs, understanding guest expectations, and utilizing sound sales strategies to provide a memorable dining experience. True mastery, per the Advanced and Master Sommelier service guidelines, extends beyond mechanics and lies in the ability to anticipate guests' needs, exceed expectations, and apply strategic salesmanship. Candidates who perform technically but fail to engage meaningfully with the guest scenario will not achieve the scores required to pass.

• Service mechanics are the foundation, but guest engagement and salesmanship are weighted equally in CMS assessments
• All three sections of the Certified Sommelier Examination must be passed simultaneously; a strong tasting score cannot compensate for a failed service section
• At the Master Sommelier level, the minimum passing score rises to 75% in each section, and the oral theory examination must be passed before the service and tasting sections are attempted
• The CMS recognizes its service standards are formal and demanding, and that candidates must display mastery of highly exacting fine dining room skills to succeed

The Certified Sommelier Examination is a one-day, in-person-only program held internationally. The 45-question theory exam must be completed in 38 minutes, the blind tasting of four wines (two white, two red) in 30 minutes, and the hospitality and service practical approximates a real restaurant environment with Master Sommeliers acting as guests. A minimum score of 60% in all three sections simultaneously is required to pass. The Advanced Sommelier examination splits into a theory portion (administered at Pearson VUE testing centers) taken before a separate practical and tasting examination, and all three parts must be passed within the same calendar year. At the Master Sommelier level, the minimum passing score is 75% per section, and candidates have a three-year window to pass all three parts after passing theory.

• The Certified Sommelier pass rate averages approximately 66% of applicants according to the Court of Master Sommeliers, Americas
• At the Master Sommelier level, the typical pass rate is approximately 3 to 8 percent of applicants, and the minimum passing score is 75% in each section
• Advanced Sommelier candidates must have at least two years of restaurant service or sales experience within the previous seven years before applying
• The Krug Cup is awarded to any candidate who passes all three parts of the Master Sommelier Diploma Examination on their first attempt
