Preheat the oven to 350F. In a large bowl, mix the flour and sugar. Stir in the basil, then the beer. Mix until thoroughly blended, then pour into a well greased 9x5x3" loaf pan. Bake until a straw inserted in the center comes out clean, about 50 minutes. Turn the bread out of the pan and cool on a rack. Slice the bread thinly.
