Heat the olive oil in a large pot over medium heat. Season the beef and sausage with salt and pepper to taste. Cook, stirring frequently, until the beef and sausage are browned and golden, about 8 to 10 minutes. With a slotted spoon, remove the meat and place it on a plate. Place aside.
Turn the heat down to medium-low. Stir in the onions, peppers, and garlic to coat. Add a pinch of salt to taste. Cook for 5 to 6 minutes, or until softened. Stir and mash the tomato paste, chili powder, cumin, oregano, paprika, cinnamon, and chili flakes into the peppers and onions. Cook, stirring frequently, until the tomato paste darkens in color, about 5 minutes. Reintroduce the beef to the mixture. Pour in the bottle of beer to deglaze the pan, stirring any browned bits to the bottom with a wooden spoon.
Combine the crushed tomatoes, fire roasted tomatoes, beans, and maple syrup in a mixing bowl. Bring the ingredients to a boil. Cook for at least one hour, or until the sauce has thickened to your liking and the flavor has developed.
