Rinse the shrimp and place to the side on paper towels to dry.
In a large pot mix the water, beer, and Old Bay. Bring the mixture to a boil.
Add the shrimp, reduce the heat to medium-high, stir, and then cover for 4 minutes. Stir once half way through.
Check the shrimp to see if they are pink. If they are. drain the shrimp and move them to a serving plate. If not, cook them until they are pink (typically 1 to 2 additional minutes).
On the serving plate, sprinkle the shrimp with Old Bay and then serve with salsa, cocktail sauce, and/or lemons.
