Combine ingredients (with a dutch whisk) in a large bowl. Once fully incorporated into a wet shaggy dough, cover with a bowl cover (or kitchen towel).
After 1 hour, do the first set of stretch and folds. Using your hands, pull the dough from one side of the bowl, straight up and then fold over the top. Rotate the bowl a quarter turn and repeat until you have made 2 full turns of the bowl (8 stretch and folds total). Cover bowl again and repeat 2 more times at one hour intervals.
Leave the dough to continue to proof (bulk ferment) for 10-15 hours more.
Preheat oven to 460degF
Turn dough out on to a floured surface. Roll and form into a round shape. Use a bench scraper to divide the dough instead to 8 equal pieces. Shape the dough into elongated roll shapes. Cover with towel until oven has reached temperature.
Carefully place shaped dough on parchment covered baking sheet. Bake for 40 minutes.
Remove from the oven and carefully transfer the bread to a cooling rack.
Let the bread cool for at least an hour before cutting. (4 hours is better)
