1. Whisk flour, yeast, and salt in large bowl. Add water, beer, and vinegar. Using rubber spatula, fold mixture, scraping up dry flour from bottom of bowl until shaggy ball forms. Cover bowl with plastic wrap and let sit at room temperature for 8 to 18 hours.

2. Lay 12 x 18-inch sheet of parchment paper inside 10-inch skillet and spray with nonstick cooking spray. Transfer dough to lightly floured work surface and knead 10 to 15 times. Shape dough into ball by pulling edges into middle. Transfer dough, seam-side down, to parchment-lined skillet and spray surface of dough with nonstick cooking spray. Cover loosely with plastic wrap and let rise at room temperature until dough has doubled in size and does not readily spring back when poked with finger, about 2 hours.

3. Adjust oven rack to lowest position. Lightly flour top of dough, and using razor blade or sharp knife, make one 6-inch-long, 1/2-inch-deep slit along top of dough. Pick up dough by lifting parchment overhang and lower into 6 to 8-quart heavy-bottomed Dutch oven (let any excess parchment hang over pot edge). Cover pot and place in oven. Heat oven to 425°F. Once oven has reached 425°F, bake bread for 30 minutes.

4. Remove lid and continue to bake until loaf is deep brown and instant-read thermometer inserted into center registers 210°F, 20 to 30 minutes longer. Carefully remove bread from pot; transfer to wire rack and cool to room temperature, about 2 hours.
