Gourmet has become somewhat debased by marketing usage, and is considered by some a pretentious middlebrow term. Such users tend to prefer terms such as artisanal (emphasizing the craft) for fine food.
Gourmet emphasizes interest in quality of food and enjoyment of eating, sometimes to an obsessive degree: someone who “lives to eat rather than eating to live”. By contrast, a gourmand is someone more interested in quantity of food than quality.
 Borrowing from French gourmet, from Middle French gourmet, from Old French groumet (“wine broker, valet in charge of wines, servant”) from Old French grommes (“manservant”), of Germanic origin, akin to Middle English grom, grome (“boy, valet, servant”), of unknown origin, perhaps from Old English *grōma (“male child, boy, youth”) from Old English grōwan (“to grow”).
