6.1 CMS Wine Service Protocol & Glassware Standards

6.1 CMS Wine Service Protocol & Glassware Standards

The Court of Master Sommeliers (CMS) has established rigorous standard operating procedures for dining room beverage service. The primary objectives of formal wine service are guest comfort, technical precision, hygiene, and understated efficiency. Every action performed by the sommelier—from approaching the table to presenting the cork—is designed to highlight the beverage, respect the host, and ensure a seamless hospitality experience. Candidates preparing for the CMS Introductory Sommelier Examination must master the exact steps of still wine service, bottle handling mechanics, and glassware alignment.

Pre-Service Preparation & Glassware Alignment

Superior wine service begins before the bottle ever reaches the dining table. Prior to opening service, the sommelier must ensure all glassware is impeccably clean, free of water spots or detergent film, and completely odor-neutral. Glassware should be polished using pure boiling water steam and clean microfiber cloths designated exclusively for glass polishing.

Glassware Selection & Stem Handling

Glassware architecture directly impacts the organoleptic perception of wine. Bowl size, rim diameter, and glass volume dictate aroma concentration and palate delivery:

• Still White & Rosé Wines: Served in smaller tulip-shaped or ISO glasses (8 to 12 oz capacity). The narrower bowl preserves cool serving temperatures, concentrates delicate floral and fruit aromas, and directs the wine toward the tip and sides of the tongue.
• Full-Bodied Red Wines: Served in larger Bordeaux-style bowls (18 to 24 oz capacity). The generous volume allows alcohol vapors to dissipate, provides surface area for oxidation, and softens intense tannins.
• Light Red Wines (Pinot Noir / Nebbiolo): Served in wide Burgundy-style bowls (20 to 26 oz capacity) featuring a spherical shape that traps volatile aromatic compounds.
• Sparkling Wines: Served in tall flutes or tulip glasses (6 to 9 oz capacity) to preserve carbonation and visual bubble chains (effervescence).

When setting the table, glasses are placed to the right of the guest, directly above the tip of the dinner knife. All glassware must be handled strictly by the stem or base, never by the bowl, to maintain pristine cleanliness and prevent heat transfer from the sommelier's hands.

The Step-by-Step Table Service Sequence

The CMS table service protocol dictates a precise sequence of movement around the dining table. Sommeliers move in a clockwise direction around the table whenever pouring or serving, always operating from the guest's right side using their right hand.

1. Verification & Bottle Presentation

Upon receiving the wine order, the sommelier retrieves the correct bottle from the cellar, ensuring the vintage and producer match the guest's selection exactly. The bottle is brought to the table resting on a clean folded linen service napkin (serviette).

Standing to the right of the host (the guest who ordered the wine), the sommelier presents the bottle with the front label clearly facing the host. The sommelier verbally confirms the five key details of the bottle:

1. Producer Name (e.g., Domaine Leflaive)
2. Designation / Vineyard (e.g., Clavoillon)
3. Appellation of Origin (e.g., Puligny-Montrachet Premier Cru)
4. Grape Variety (or style classification, e.g., Chardonnay)
5. Vintage Year (e.g., 2020)

Upon receiving verbal or physical confirmation from the host, the sommelier prepares to open the bottle.

Capsule Cutting & Cork Removal Mechanics

Bottle opening must occur on a stable surface or guerrilla cart (guéridon), or held securely in the sommelier's hands at waist level without resting the bottle against the body or table. The bottle must remain stationary during capsule cutting; turning the bottle during opening is considered poor technique.

Cutting the Foil Capsule

Using the small foil cutter blade of a standard waiter's key (corkscrew), the sommelier cuts the capsule cleanly below the lower lip (second drip ring) of the bottle neck. Cutting beneath the lower lip ensures that when the wine is poured, liquid never comes into direct contact with foil edges, preventing potential metal contamination or tarnished off-flavors. The removed top foil cap is placed discretely into the sommelier's apron pocket. The exposed top of the cork and bottle lip are wiped thoroughly with the serviette to remove dust, mold, or cellar residue.

Cork Extraction Protocol

The worm (spiral helix) of the corkscrew is inserted directly into the geometric center of the cork. Driving the worm straight prevents cork breakage or crumbling. The worm is rotated clockwise until approximately one half-turn of the spiral remains visible above the cork, ensuring the worm does not pierce entirely through the bottom of the cork into the wine.

Using the hinged lever of the waiter's key against the upper bottle lip, the sommelier gently extracts the cork upward. Just before the cork is completely released, the sommelier removes the lever arm and gently extracts the cork by hand to avoid a loud popping sound. A silent extraction demonstrates refined professional technique.

Cork Presentation & Final Bottle Wipe

The extracted cork is unscrewed from the worm and inspected visually for moisture, sound structure, or signs of seepage. The cork is then placed onto a small underliner glass dish or coaster to the immediate right of the host's place setting. The neck of the bottle is wiped inside and outside with the serviette to remove any remaining cork fragments.

Pouring, Tasting Splash, & Table Management

With the bottle opened and wiped, the sommelier prepares to serve the table:

1. The Host Tasting Splash: Standing to the host's right, the sommelier pours a 1 to 1.5 ounce tasting splash into the host's glass, holding the bottle with the label facing upward toward the host. The sommelier steps back and waits patiently while the host evaluates the wine's appearance, aroma, and palate for sound quality.
2. Serving the Table: Upon receiving the host's approval, the sommelier proceeds clockwise around the table. Standard priority dictates serving female guests first in clockwise sequence, followed by male guests in clockwise sequence, and concluding with the host last regardless of gender. If no clear host exists or if dining is informal, service proceeds strictly clockwise from the person to the host's left.
3. Pouring Technique & Volume: The standard pour volume for still wine is 4 to 5 ounces per glass, which typically corresponds to filling the glass to the widest diameter of the bowl. Filling to the widest point maximizes surface area exposure for aromatic expression. Each pour is finished with a smooth upward twist of the bottle wrist over the glass to catch stray drops, followed by a light wipe of the bottle neck with the serviette.
4. Bottle Placement: Once all guests are served, the remaining wine bottle is placed to the right of the host's glass or centered on the table on a clean coaster, oriented with the front label facing the guests. If serving white, rosé, or sparkling wine, the bottle is placed in an insulated wine chiller or ice bucket containing equal parts ice and cold water.
