In a large bowl, or the bowl of your stand mixer, combine the flour, yeast, beer, and salt.
Using the dough hook on low speed, mix until a dough starts to form and there’s no dry flour left, about 2 minutes. Scrape down the sides of the bowl if needed.
Once the dough has come together, knead it in the mixer for about 5 minutes, or until the dough is smooth and elastic.
Cover the bowl with plastic wrap or a damp kitchen towel and let the dough rise for 1 ½ to 2 hours, or until it doubles in size.
Line a Dutch oven with parchment paper and lightly dust it with flour.
Shape the dough into a ball by pulling the edges into the center. Place it in the middle of the Dutch oven, seam side down. Let it rest for 40 minutes to 1 hour, or until it looks puffy and light.
Preheat the oven to 400°F. Adjust your oven rack to the middle position.
Using a sharp knife or razor, score the top of the loaf with two ¼-inch deep cuts, forming a cross.
Cover the Dutch oven with its lid and place it in the oven. Bake the bread for 25 minutes.
After 25 minutes, carefully remove the lid and continue baking for another 30 minutes, or until the loaf is a deep golden brown on top.
Remove the bread from the Dutch oven and transfer it to a wire rack.
Let the bread cool completely before slicing and serving.
