As it happens, my dad is the chairman of the Sommelier Society of America.
A sommelier is a wine educator — it’s that person in a good restaurant who knows anything and everything about wine. The sommelier can guide you on the best choices based on what you’ll be eating tonight.
A sommelier is also, almost by definition, a wine marketer.
It’s the sommelier’s job to create a fantastic experience for the customer, so that the customer buys more wine.
In that sense, they’re true content marketers, using their depth of knowledge to make customers happy and to do more business.
