A sommelier (/ˈsɒməljeɪ/ or /sʌməlˈjeɪ/; French
pronunciation: ​[sɔməlje]), or wine steward, is a trained and knowledgeable
wine professional, normally working in fine restaurants, who specializes in all
aspects of wine service as well as wine and food pairing. The role is more
specialized and informed than that of a wine waiter.
