Chill 2 tall beer tumblers in the freezer. Put the salt into a shallow dish. Remove the glasses from the freezer and wet the rims using a wedge of lime. Dip the glass rims into the salt to cover. Add the lime wedges and ice into the glasses, then add a pinch of chili powder to each glass. Stir in 1 teaspoon of light brown sugar to each glass and 4 dashes of hot sauce. Top off with beer and serve immediately.
