Rimming glasses adds flavor and pizazz to many types of cocktails. Bartenders can rim glasses with salt, sugar, or spices such as cinnamon, to provide an easy but impressive way to present cocktails to their customers. With a glass rimmer, the task of rimming a glass is made simple. Simply place the spices in each section, such as salt and sugar, then you dip the rim of the glass in the sponge that holds your lemon or lime juice. Once moistened, you then dip the rim into the spices and voila, in seconds you have perfectly rimmed glasses. Bartenders will often rim a number of glasses at a time and have them ready for use when needed.
