Place Castle Michelada Blend (or other chile-salt mixture) or salt in a small, shallow dish. To create a salt rim, rub a pint or pilsner glass’s rim with the cut side of the reserved juiced lime half.
Place the glass right side up and fill it with lime juice, Worcestershire sauce, and hot sauce. Put a pinch of salt on the ice, pour beer over it, and top it off with ice. Add a little stir if you want it to mix up a bit. As you drink, top up the remaining beer.
