In a medium bowl stir together the olive oil, beer, soy sauce, garlic, ginger, brown sugar. Add the salmon. Allow to marinate at room temperature for 15 minutes.
Preheat the broiler. Add the salmon to a baking sheet that has been covered with aluminum foil, pour the marinade into a saucepan.
Bring the marinade to a boil, stirring frequently until thickened, about 6 minutes.
Brush salmon with glaze, place under broiler for 2 minutes, remove from oven, re-brush with glaze and broil for two minutes, repeating this step until salmon flakes easily with fork.
