Beer lovers prefer to slake their thirst from the lip of a frosted beer mug. The ice-cold glass delivers a bracing chill to the beer and feels good in the hand on a hot day. You can spend hundreds of dollars on a chiller for your barware, or you can do it at home with appliances you aready own in about an hour.
Whether you prefer to serve beer in a monstrous glass with a curved handle, a tapered Pilsner glass or a pint mug, the trick to getting a good layer of frost is to clean your glassware first. Wash and rinse the glasses so there is no trace of soapy liquid. If you run them through the dishwasher, allow your glasses to cool to room temperature before frosting.
Run cold tapwater over the glasses one at a time, inside and out, pour out excess water and place them immediately in the freezer, right side up. Do not wipe off or shake water off the glasses. Wet glassware is what gets a good frost building on your mug.
Circulate Cold Air
Leave some space between the mugs so air can circulate around them. Allow at least an hour for the frost to accumulate before you pour the beer. If you're in a hurry, pour crushed ice into your mugs and swirl it around to build a layer of frost, then pop the glasses in the freezer for a few minutes.
