Preheat the oven to 350°F. Grease a 9" x 5" inch loaf pan.
In a medium bowl, whisk together the flour, sugar, baking powder, spices and salt. Using a wooden spoon, stir the beer and pumpkin puree into the dry ingredients until just mixed. Barely mix the dough. Just a few strokes to make sure all the ingredients had come together and all the dry ingredients are incorporated, otherwise the middle of the bread will not cook properly.
Pour/Scoop batter into loaf pan. Add melted butter over top of the loaf.
Bake for 50 to 60 minutes, until top is golden brown and a toothpick/knife inserted in the middle comes out clean.
