Sommeliers usually work in fine restaurants and specialize in all aspects of wine and how wines match with foods.
I consider myself to be rather high-brow since I enjoy tasting expensive wines. Do you like wine tasting? I know that it is actually the sensory evaluation and examination of wine I do, and wasting money on expensive ones makes me feel better about myself. Do you consider yourself a sommelier, which is a professional wine taster? I usually avoid labelling myself but in this case it might be appropriate!
A sommelier ( or ; ), 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.
