If you are hosting a cocktail party, it is a good idea to know a few basic bartending tricks. Many people enjoy drinking beer, or other cocktails, from a frosted mug or glass. Frosting a glass is a very simple procedure. Several different methods may be used to frost a glass or beer mug; experiment with the techniques and choose the one that works best for you.
Rinse the glass with cold water and place it in a freezer for 30 minutes to an hour. Remove the glass after it has a coating of frost.
Insert the glass into a bucket of shaved ice. Allow the glass to sit in the ice for 15 minutes.
Fill the glass with ice and water. Stir the ice for several minutes until the glass is frosted.
Make a sugar-frosted glass. Prechill the glass by storing in a freezer; remove the glass after it is frosted. Moisten the rim with slice of lemon or lime, then dip it in powered sugar.
