Who We Are

The International Sommelier Guild (ISG) is a collection of individuals who share a common goal: to provide the world’s finest, most complete Sommelier education. The ISG’s certified Sommelier instructors bring a wealth of hospitality experience and educational training into our online and classroom deliveries. Among our instructors are chefs, restaurant owners, hospitality consultants, wine directors, importers, distributors, and retailers. What binds our network of instructors together is a love for sharing their experience and knowledge with students and the common goal of helping novice wine lovers achieve their goals in the wine and hospitality communities.

What We Do

The ISG approaches wine studies from a global perspective. Our curriculum is progressive, broad, and provides students with up-to-date information both on the traditional wine, beer and spirits of Europe and the new world as well as commentary on emerging Asian nations. In addition, the ISG trains students in service and management techniques applicable to the global hospitality industry. The ISG recognizes that direct contact with locally-based, passionate instructors is the best way for students to build a foundation of knowledge that will help them realize their goals.

One of the ISG’s most important goals is to provide our students with a standardized, globally-relevant curriculum. All of our certified Sommelier instructors are asked to contribute to the knowledge base which informs our curriculum. Our instructors attend regular teacher training sessions where their own experiences contribute to the development of ISG course material. The ISG combines a standardized curriculum with proven adult education techniques to prepare our students for a professional life in the wine and hospitality industries.

How We Do it

The International Sommelier Guild (ISG) provides online and classroom based education from a curriculum developed by wine and hospitality industry professionals. All of our certified Sommelier instructors are provided with standardized textbooks, instructional manuals, presentation material, and examinations to ensure consistent, high quality education in all of the ISG’s educational deliveries.
In essence, every ISG course expresses the sum total of the knowledge and experience of all of our certified Sommelier instructors. Our students and graduates become parts of this extraordinary community of wine and hospitality industry professionals.
