Chill 6 beer mugs until very cold. Add some salt to a shallow dish. Moisten the rims with a lime wedge and coat with salt. Add ice and 2 tablespoons lime juice to each mug. Pour in the beer and drink before the ice melts.
*It's important to use fresh lime juice, it makes all the difference in flavor!;
