History of the Sommelier Profession

The sommelier profession carries a documented institutional lineage stretching from the royal courts of medieval Europe to the credentialed, examination-based discipline recognized across the modern hospitality industry. This page traces the structural evolution of the role — from household officer to licensed wine professional — and identifies the key transitions that shaped the qualification frameworks, professional organizations, and service standards visible across the sommelier profession today.

Definition and scope

The sommelier's role as a formal occupational category emerged from the administrative structures of European aristocratic households, where a designated officer managed the transport and service of provisions, including wine and table settings. By the late medieval period in France, the somme (pack animal tasked with carrying supplies) gave rise to the sommier and later the sommelier — a title designating the official responsible for the lord's table stores.

By the 18th and 19th centuries, the role had narrowed decisively toward wine management in fine dining establishments. Paris's grand restaurants of the post-Revolutionary period institutionalized the position, creating a functional specialization distinct from general wait staff. The sommelier in this context was responsible for the cellar inventory, wine procurement, and tableside service — a tripartite scope that still defines the role's core responsibilities in formal establishments.

The 20th century introduced formal credentialing structures. The Court of Master Sommeliers, founded in the United Kingdom in 1977, established the Master Sommelier diploma as the highest standardized credential in the profession. The Wine and Spirits Education Trust, incorporated in 1969, introduced a parallel educational framework with four certification levels, from Level 1 through the Diploma. These two bodies remain the dominant institutional references for credential verification across the US and UK markets.

How it works

The professional history of the sommelier is best understood as a series of institutional formalization events, each of which converted informal guild knowledge into testable, transferable standards.

1. Pre-institutional phase (pre-1900): Knowledge transmission was apprenticeship-based, with no standardized examination. Expertise was regional, often proprietary to specific estates or restaurant houses, and not portable across employers or national borders.

2. Early credentialing phase (1969–1977): WSET's founding in 1969 and the Court of Master Sommeliers' establishment in 1977 introduced the first examination hierarchies. The inaugural Master Sommelier examination was administered in 1969 in the UK; the first American Master Sommeliers passed the examination in 1982.

3. North American expansion (1977–2000): The Court of Master Sommeliers Americas was established as an autonomous chapter. The certified sommelier vs. master sommelier distinction became a recognized professional demarcation in US hospitality hiring.

4. Proliferation of certifying bodies (2000–present): The Society of Wine Educators, the American Sommelier Association, and the International Sommelier Guild entered the US credentialing landscape, each with distinct examination frameworks. As of the most recent published count by the Court of Master Sommeliers, fewer than 270 individuals worldwide hold the Master Sommelier diploma — a figure that reflects the examination's historically low pass rate.

5. Industry integration phase: Sommelier career path structures became standardized in larger hotel groups and restaurant corporations, with titles progressing from Certified Sommelier to advanced and master levels.

Common scenarios

The historical arc of the sommelier profession produces distinct credential profiles depending on the era in which a professional trained and the institutional path followed.

Pre-credential practitioners — common in establishments founded before the WSET and CMS frameworks became widespread — hold expertise validated through tenure, employer reputation, and peer recognition rather than formal examination. These professionals are most commonly encountered in long-established European fine dining contexts or in US wine regions with deep independent restaurant cultures such as Napa Valley and New York City.

Single-body credential holders follow one of the two dominant tracks — CMS or WSET — and the choice often reflects geographic or employer influence. CMS credentials are more prevalent in US front-of-house hiring; WSET credentials carry stronger weight in import, distribution, and retail contexts (wine-and-spirits-education-trust).

Multi-credential professionals hold qualifications from two or more bodies, a pattern that became more common after 2000 as sommelier continuing education resources expanded and employers began requiring complementary competencies in spirits and beverage program management beyond wine alone.

Decision boundaries

Three structural distinctions define how professional history maps to contemporary practice in the sommelier sector.

Credentialed vs. non-credentialed status: The profession in the United States carries no statutory licensing requirement at the federal or state level. Unlike trades regulated under occupational licensing statutes, the sommelier title is unprotected — any individual may use it regardless of certification status. The professional significance of credentials therefore derives entirely from market recognition and employer standards rather than legal enforcement.

Old-credential vs. current-credential validity: The CMS and WSET examination frameworks have been revised at intervals, meaning that credential holders from different eras passed different versions of the examination. The CMS last revised its examination structure in 2012 for the Certified level. Employers and researchers should note the year of credential award when evaluating equivalency.

Generalist history vs. specialist evolution: The historical sommelier role was broadly defined to include cellar management, wine service standards, and wine list construction. The contemporary role has increasingly bifurcated into front-of-house service specialists and back-of-house program directors, a split that traces directly to the expansion of large-volume beverage programs in hotel and casino hospitality after 1990.
