rim

A rim refers to the decorative or flavored border applied to the edge of a drinking glass, typically used in cocktails and mixed drinks. The rim is created by coating the outer edge of a glass with a dry ingredient—most commonly salt, sugar, or a spice blend—sometimes combined with a wet adhesive such as citrus juice, simple syrup, or egg white to ensure the coating adheres. The practice originated in Mexican bartending tradition, particularly for margaritas, though it has since become standard in bars worldwide. Salt rims (particularly with lime or lemon) remain the most traditional application, though variations using colored sugars, chili-lime blends, crushed nuts, and other spices have proliferated in contemporary mixology.

Rims are applied to cocktails and non-alcoholic beverages to enhance flavor, provide textural contrast, and add visual appeal. The salt rim on a margarita complements citrus and agave spirits, while sugar rims suit tropical drinks and sours. Specialty rims—incorporating Tajín seasoning, smoked salt, candied citrus zest, or crushed freeze-dried berries—are used in craft cocktails to layer flavor complexity and create signature drinks. Rims may also serve a functional purpose, masking the glass edge and providing grip for the drinker. Application typically involves moistening the glass rim with the relevant liquid and rolling it through the dry ingredient coating.
